More compositing goodies. - Texture Node Allows to use any Blender Texture block as input for masks or color blending. The texture node doesn't generate a real image, but adjusts to the size as mapped with during an operation. So it won't work to use it as Image input for Blur or Filter nodes. Note; the Vector inputs for this node only work with manual input now! - Translation Node Give any image an offset in X or Y direction For the Texture node to work, I needed to move the central 'pixel processor' up one level... to allow differently sized images to merge and allow 'procedural images' without size. Temporal image of the day: http://www.blender.org/bf/rt.jpg

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Changed node type definitions to use a dynamic list. This will allow python or plugin defined nodes to work as well. (And fixes compile issues with MSVC in yesterdays commit for nodes) Code provided by Nathan L. Fixes in his code: - free_nodesystem() was called too late (after guarded alloc was closed) - free_nodesystem() was freeing nodes that were not malloced even - free_nodesystem was using free, not freeN :) - the typedefs needed to be malloced yes, to allow duplicate nodes like group but also for dynamic nodes.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Long wanted feature; decent ESC processing in composite nodes. Works simple; just check for if(node->exec & NODE_BREAK) break; The main process (node processor) sets such a flag, checking for esc 20 times per second. That means you can check for ESC while doing image processing without much cpu overhead. Currently only added in blur nodes and defocus. Needs to be added all over, nice for others... needs careful tests too. What we now could do is even calling ESC on editing commands or mouseclicks in composite editor? Could give user feeling of interactive app :) Further, finished nodes are kept in memory anyway.

Four-in-one commit: (NOTE: new include dependency in Render module, might need MSVC update!

There's no gamma, brightness or multiply needed in this node, for that the Curves Node functions better. -> Enabled Toolbox in Node editor This now also replaces the SHIFT+A for adding nodes. The nodes are automatically added to the menus, using the 'class' category from the type definition.

I've tested it for 'render result' now, with the idea that this can (optionally) replace the current inserting of tiles in the main result buffers. Especially with a lot of layers, the used memory for these buffers can easily go into the 100s of megs. Two other advantages: - all 'render result' layers can be saved entirely in a single file, for later use in compositing, also for animation output. - on each render, per scene, a unique temp file can be stored, allowing to re-use these temp files on starting Blender or loading files, showing the last result of a render command. The option is currently disabled, needs more work... but I had to commit this because of the rest of the work I did! -> Bug fix The Image node didn't call an execute event when browsing another image.

Changed node type definitions to use a dynamic list. This will allow python or plugin defined nodes to work as well. (And fixes compile issues with MSVC in yesterdays commit for nodes) Code provided by Nathan L. Fixes in his code: - free_nodesystem() was called too late (after guarded alloc was closed) - free_nodesystem() was freeing nodes that were not malloced even - free_nodesystem was using free, not freeN :) - the typedefs needed to be malloced yes, to allow duplicate nodes like group but also for dynamic nodes.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Group Nodes made functional: each group now can be re-used (instanced) with SHIFT+G. This works as well for local groups as library-linked groups. Also fixed that group nodes were copying internal data to the outside, which made it impossible to use the socket-buttons to set individual values for each group-instance. Library-linked groups are prevented from editing. But, try to open a group and it will give a request for 'make local'. The make local rule is identical to other library data in blender, meaning: - if all users of the library data are local -> the library data is flagged 'local', and if needed a unique name is made - if there's mixed users (local and from other library data) it makes a full copy, and assigns this copy to all local users.

Orange; made Node types Texture and Geometry integrated in render. Means the coordinate outputs now have correct dx/dy vectors for Image AA, and texture delivers correct intensity, rgb, alpha and normal.

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree. This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

Toggle links tool for Node Editor This commit adds a new tool, Toggle Links, to the node editor. This tool allows the user to toggle the status (linked/not linked) between desired sockets. The tool can be used either by using the f key or the menus. This functionality is analogue to one found in object editing modes except for its additional toggle functionality. To use this tool, the user has to first select an input and an output socket. Selecting is done by clicking with right mouse button on a socket. After the tool has been invoked, the link between those two sockets is toggled. The result may vary based on existing linkage. There can be only one input and one output selected at maximum in a node tree. This means that if the user selects a socket while one of the same type is already selected, the old one will be deselected. The tool complements the current way of connecting nodes. One possible use for it is to use it to review output of nodes by using a viewer node. Just select wanted input socket of a viewer node, set it visible and use selection of an output socket in conjuction with f key to show the output in the viewer node. Select another output and hit f to see its output and so on.

void nodeClearActiveID(struct bNodeTree *ntree, short idtype);
Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

void NodeTagChanged(struct bNodeTree *ntree, struct bNode *node);
More compositing goodies. - Texture Node Allows to use any Blender Texture block as input for masks or color blending. The texture node doesn't generate a real image, but adjusts to the size as mapped with during an operation. So it won't work to use it as Image input for Blur or Filter nodes. Note; the Vector inputs for this node only work with manual input now! - Translation Node Give any image an offset in X or Y direction For the Texture node to work, I needed to move the central 'pixel processor' up one level... to allow differently sized images to merge and allow 'procedural images' without size. Temporal image of the day: http://www.blender.org/bf/rt.jpg

This Group Node then works just like any Node. To prevent the current code to become too complex, I've disabled the possibility to insert Groups inside of Groups. That might be enabled later, but is a real nasty piece of code to get OK. Since Group Nodes are a dynamic Node type, a lot of work has been done to ensure Node definitions can be dynamic too, but still allow to be stored in files, and allow to be verified for type-definition changes on reloading. This system needs a little bit maturing still, so the Python gurus should better wait a little bit! (Also for me to write the definite API docs for it). What works now: - Press CTRL+G to create a new Group. The grouping code checks for impossible selections (like an unselected node between selected nodes). Everthing that's selected then gets removed from the current tree, and inserted in a new NodeTree library data block. A Group Node then is added which links to this new NodeTree. - Press ALT+G to ungroup. This will not delete the NodeTree library data, but just duplicate the Group into the current tree. - Press TAB, or click on the NodeTree icon to edit Groups. Note that NodeTrees are instances, so editing one Group will also change the other users. This also means that when removing nodes in a Group (or hiding sockets or changing internal links) this is immediately corrected for all users of this Group, also in other Materials. - While editing Groups, only the internal Nodes can be edited. A single click outside of the Group boundary will close this 'edit mode'. What needs to be done: - SHIFT+A menu in toolbox style, also including a list of Groups - Enable the single-user button in the Group Node - Displaying all (visible) internal group UI elements in the Node Panel - Enable Library linking and prevent editing of Groups then. **** NEW: Socket Visibility control Node types will be generated with a lot of possible inputs or outputs, and drawing all sockets all the time isn't very useful then. A new option in the Node header ('plus' icon) allows to either hide all unused sockets (first keypress) or to reveil them (when there are hidden sockets, the icon displays black, otherwise it's blended). Hidden sockets in Nodes also are not exported to a Group, so this way you can control what options (in/outputs) exactly are available. To be done: - a way to hide individual sockets, like with a RMB click on it. **** NEW: Nodes now render! This is still quite primitive, more on a level to replace the (now obsolete and disabled) Material Layers. What needs to be done: - make the "Geometry" node work properly, also for AA textures - make the Texture Node work (does very little at the moment) - give Material Nodes all inputs as needed (like Map-to Panel) - find a way to export more data from a Material Node, like the shadow value, or light intensity only, etc Very important also to separate from the Material Buttons the "global" options, like "Ztransp" or "Wire" or "Halo". These can not be set for each Material-Node individually. Also note that the Preview Render (Buttons window) now renders a bit differently. This was a horrid piece of antique code, using a totally incompatible way of rendering. Target is to fully re-use internal render code for previews. OK... that's it mostly. Now test!

Four-in-one commit: (NOTE: new include dependency in Render module, might need MSVC update! It has to include the imbuf/intern/openexr/ directory in search path) -> New Composite node: "Hue Saturation". Works like the former 'post process' menu. There's no gamma, brightness or multiply needed in this node, for that the Curves Node functions better. -> Enabled Toolbox in Node editor This now also replaces the SHIFT+A for adding nodes. The nodes are automatically added to the menus, using the 'class' category from the type definition. Current classes are (compositor examples): Inputs: RenderResult, Image Outputs: Composite, Viewer Color Ops: RGB Curves, Mix, Hue Saturation, AlphaOver Vector Ops: Normal, Vector Curves, Map Value Filters: Filter, Blur, VectorBlur Convertors: ColorRamp, RGBtoBW, Separate RGBA, Separate HSVA, Set Alpha Generators: RGB, Value, Time Groups: the list of custom defined nodes -> OpenEXR tile saving support Created an API for for saving tile-based Images with an unlimited amount of layers/channels. I've tested it for 'render result' now, with the idea that this can (optionally) replace the current inserting of tiles in the main result buffers. Especially with a lot of layers, the used memory for these buffers can easily go into the 100s of megs. Two other advantages: - all 'render result' layers can be saved entirely in a single file, for later use in compositing, also for animation output. - on each render, per scene, a unique temp file can be stored, allowing to re-use these temp files on starting Blender or loading files, showing the last result of a render command. The option is currently disabled, needs more work... but I had to commit this because of the rest of the work I did! -> Bug fix The Image node didn't call an execute event when browsing another image.

Orange: more noodle updates! **** NEW: Group Nodes Node trees usually become messy and confusing quickly, so we need not only a way to collapse Nodes into single 'groups', but also a way to re-use that data to create libraries of effects. This has been done by making a new Library data type, the NodeTree. Everything that has been grouped is stored here, and available for re-use, appending or linking. These NodeTrees are fully generic, i.e. can store shader trees, composit trees, and so on. The 'type' value as stored in the NodeTree will keep track of internal type definitions and execute/drawing callbacks. Needless to say, re-using shader trees in a composit tree is a bit useless, and will be prevented in the browsing code. :) So; any NodeTree can become a "Goup Node" inside in a NodeTree.

Orange; daily noodler update commit. - Adding execution code for Node trees. Was a bit a puzzle, since I want it to be multithreading by design. This now is solved by defining a stack per tree for all data that's being written into. This stack, which resides now in the NodeTree itself, then can be allocated per thread. - For testing pleasure, I've added a 'mix node' and a 'show node', so you can already see it do something. :) - reshuffled structure, to put things nice together, and have easier node adding. Current state is still WIP though, structure might change. For the record; new file node_shaders.c will contain all shader node definitions, apart from the drawing callbacks. Next: I'm going to check on Andrea's work on icons now, since this is very much needed for true shader/composit work. Now back to release work...

Orange: daily noodle updates; - Texture Node: now displays 'intensity values' in node too, and has input, and shows in buttons when activated in Node editor.

The Normal Node has optional vector input, and delivers a dot product then. This can be used as a blending factor between nodes, or for fake extra light in a certain direction. - New: "Geometry Node". This actually replaces the Input node. It offers all coordinates (vectors) as being the starting point for shading and for textures. Note: for preview render this doesn't give much different results yet... this is the start for real render support! - http://www.blender.org/bf/rt5.jpg The two new nodes in action - Bugfix: the "Block" button (which delivers popups) did not return a correct event when nothing happened (mouse moved out), which could cause mouse clicks to be passed on to the queue.

#define SH_NODE_MAPPING 109
Orange: - New UI element: the "Curve Button". For mapping ranges (like 0 - 1) to another range, the curve button can be used for proportional falloff, bone influences, painting density, etc. Most evident use is of course to map RGB color with curves. To be able to use it, you have to allocate a CurveMapping struct and pass this on to the button. The CurveMapping API is in the new C file blenkernel/intern/colortools.c It's as simple as calling: curvemap= curvemapping_add(3, 0, 0, 1, 1) Which will create 3 curves, and sets a default 0-1 range. The current code only supports up to 4 curves maximum per mapping struct. The CurveMap button in Blender than handles allmost all editing. Evaluating a single channel: float newvalue= curvemapping_evaluateF(curvemap, 0, oldval); Where the second argument is the channel index, here 0-1-2 are possible. Or mapping a vector: curvemapping_evaluate3F(curvemap, newvec, oldvec); Optimized versions for byte or short mapping is possible too, not done yet. In butspace.c I've added a template wrapper for buttons around the curve, to reveil settings or show tools; check this screenie: http://www.blender.org/bf/curves.jpg - Buttons R, G, B: select channel - icons + and -: zoom in, out - icon 'wrench': menu with tools, like clear curve, set handle type - icon 'clipping': menu with clip values, and to dis/enable clipping - icon 'x': delete selection In the curve button itself, only LMB clicks are handled (like all UI elements in Blender). - click on point: select - shift+click on point: swap select - click on point + drag: select point (if not selected) and move it - click outside point + drag: translate view - CTRL+click: add new point - hold SHIFT while dragging to snap to grid (Yes I know... either one of these can be Blender compliant, not both!) - if you drag a point exactly on top of another, it merges them Other fixes: - Icons now draw using "Safe RasterPos", so they align with pixel boundary. the old code made ints from the raster pos coordinate, which doesn't work well for zoom in/out situations - bug in Node editing: buttons could not get freed, causing in memory error prints at end of a Blender session. That one was a very simple, but nasty error causing me all evening last night to find! (Hint; check diff of editnode.c, where uiDoButtons is called) Last note: this adds 3 new files in our tree, I did scons, but not MSVC!

== Shader nodes == * Geometry node: Front/back output This is used as a mask for determining whether you're looking at the front side or back side of a mesh, useful for blending materials, my practical need was giving different materials to the pages of a magazine: http://mke3.net/blender/etc/frontback-h264.mov Give 1.0 if it's the front side, and 0.0 if it's the back side. * Extended material node This is the same as the material node, but gives more available inputs and outputs, (basically just connecting up more of ShadeInput and ShadeResult to the node). I didn't want to add it to the normal simple Material node since you don't always need all that stuff, and it would make the node huge, but when you do need it, it's nice to have it. == Comp nodes == * Invert node Inverting is something that happens all the time in a node setup, and this makes it easier. It's been possible to invert previously by adding a mix node and subtracting the input from 1.0, but it's not the best way of doing it. This node: - makes it a lot faster to set up, rather than all the clicking required with the mix node - is a lot more usable amidst a complex comp setup, when you're looking at a node tree, it's very helpful to be able to see at a glance what's going on. Using subtract for inverting is easily mixed up with other nodes in which you are actually subtracting, not inverting, and looks very similar to all the other mix nodes that usually litter a comp tree. - has options to invert the RGB channels, the Alpha channel, or both. This saves adding lots of extra nodes (separate RGBA, subtract, set alpha) when you want to do something simple like invert an alpha channel. I'd like to add this option to other nodes too. There's also a shader node version too. * Also a few fixes that I committed ages ago, but seems to have been overwritten in Bob's node refactor: - adding new compbufs to the set alpha and alphaover nodes when you have only one noodle connected to the lower input - making the fac value on RGB curves still work when there's nothing connected to it

Christmas coding work! ********* Node editor work: - To enable Nodes for Materials, you have to set the "Use Nodes" button, in the new Material buttons "Nodes" Panel or in header of the Node editor. Doing this will disable Material-Layers. - Nodes now execute materials ("shaders"), but still only using the previewrender code. - Nodes have (optional) previews for rendered images. - Node headers allow to hide buttons and/or preview image - Nodes can be dragged larger/smaller (right-bottom corner) - Nodes can be hidden (minimized) with hotkey H - CTRL+click on an Input Socket gives a popup with default values. - Changing Material/Texture or Mix node will adjust Node title. - Click-drag outside of a Node changes cursor to "Knife' and allows to draw a rect where to cut Links. - Added new node types RGBtoBW, Texture, In/Output, ColorRamp - Material Nodes have options to ouput diffuse or specular, or to use a negative normal. The input socket 'Normal' will force the material to use that normal, otherwise it uses the normal from the Material that has the node tree. - When drawing a link between two not-matching sockets, Blender inserts a converting node (now only for value/rgb combos) - When drawing a link to an input socket that's already in use, the old link will either disappear or flip to another unused socket. - A click on a Material Node will activate it, and show all its settings in the Material Buttons. Active Material Nodes draw the material icon in red. - A click on any node will show its options in the Node Panel in the Material buttons. - Multiple Output Nodes can be used, to sample contents of a tree, but only one Output is the real one, which is indicated in a different color and red material icon. - Added ThemeColors for node types - ALT+C will convert existing Material-Layers to Node... this currently only adds the material/mix nodes and connects them. Dunno if this is worth a lot of coding work to make perfect? - Press C to call another "Solve order", which will show all possible cyclic conflicts (if there are). - Technical: nodes now use "Type" structs which define the structure of nodes and in/output sockets. The Type structs store all fixed info, callbacks, and allow to reconstruct saved Nodes to match what is required by Blender. - Defining (new) nodes now is as simple as filling in a fixed Type struct, plus code some callbacks. A doc will be made! - Node preview images are by default float ********* Icon drawing: - Cleanup of how old icons were implemented in new system, making them 16x16 too, correctly centered *and* scaled. - Made drawing Icons use float coordinates - Moved BIF_calcpreview_image() into interface_icons.c, renamed it icon_from_image(). Removed a lot of unneeded Imbuf magic here! :) - Skipped scaling and imbuf copying when icons are OK size ********* Preview render: - Huge cleanup of code.... - renaming BIF_xxx calls that only were used internally - BIF_previewrender() now accepts an argument for rendering method, so it supports icons, buttonwindow previewrender and node editor - Only a single BIF_preview_changed() call now exists, supporting all signals as needed for buttos and node editor ********* More stuff: - glutil.c, glaDrawPixelsSafe() and glaDrawPixelsTex() now accept format argument for GL_FLOAT rects - Made the ColorBand become a built-in button for interface.c Was a load of cleanup work in buttons_shading.c... - removed a load of unneeded glBlendFunc() calls - Fixed bug in calculating text length for buttons (ancient!)

/* the type definitions array */
Changed node type definitions to use a dynamic list. This will allow python or plugin defined nodes to work as well. (And fixes compile issues with MSVC in yesterdays commit for nodes) Code provided by Nathan L. Fixes in his code: - free_nodesystem() was called too late (after guarded alloc was closed) - free_nodesystem() was freeing nodes that were not malloced even - free_nodesystem was using free, not freeN :) - the typedefs needed to be malloced yes, to allow duplicate nodes like group but also for dynamic nodes.

Fix for bug #5680: Vertex color node worked only if VCol Paint/Light was enabled. Fixed that, and removed the vertex color node making it part of the geometry node instead. Also, preview.blend had black vertex colors for the sphere, so set them to white like the other primitives.

3 very simple new composite nodes that I wanted for working with here. Hope the code is ok, they work ok in testing here and get done what I need, any checks or fixes are welcome. * Separate RGBA: Separates an input RGBA image into its R, G, B and A channels * Separate HSVA: Separates an input RGBA image into H, S, V and A channels * Set Alpha: Takes an input RGBA image and an alpha value channel and combines them into a single RGBA image channel. You can also set the alpha for the entire image with the number field when there's no input alpha channel. TODO: Allow input alpha channel with no input image, in order to output a solid colour, with alpha.

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Orange; more render & compo stuff! -> Rendering in RenderLayers It's important to distinguish a 'render layer' from a 'pass'. The first is control over the main pipeline itself, to indicate what geometry is being is rendered. The 'pass' (not in this commit!) is related to internal shading code, like shadow/spec/AO/normals/etc. Options for RenderLayers now are: - Indicate which 3d 'view layers' have to be included (so you can render front and back separately) - "Solid", all solid faces, includes sky at the moment too - "ZTransp", all transparent faces - "Halo", the halos - "Strand", the particle strands (not coded yet...) Currently only 2 'passes' are exported for render, which is the "Combined" buffer and the "Z. The latter now works, and can be turned on/off. Note that all layers are still fully kept in memory now, saving the tiles and layers to disk (in exr) is also todo. -> New Blur options The existing Blur Node (compositor) now has an optional input image. This has to be a 'value buffer', which can be a Zbuffer, or any mask you can think of. The input values have to be in the 0-1 range, so another new node was added too "Map Value". The value input can also be used to tweak blur size with the (todo) Time Node. Temporal screenies: http://www.blender.org/bf/rt.jpg http://www.blender.org/bf/rt1.jpg http://www.blender.org/bf/rt2.jpg BTW: The compositor is very slow still, it recalulates all nodes on each change still. Persistant memory and dependency checks is coming!

Three features; - Live scanline updates while rendering Using a timer system, each second now the tiles that are being processed are checked if they could use display. To make this work pretty, I had to use the threaded 'tile processor' for a single thread too, but that's now proven to be stable. Also note that these updates draw per layer, including ztransp progress separately from solid render. - Recode of ztransp OSA Until now (since blender 1.0) the ztransp part was fully rendered and added on top of the solid part with alpha-over. This adding was done before the solid part applied sub-pixel sample filtering, causing the ztransp layer to be always too blurry. Now the ztransp layer uses same sub=pixel filter, resulting in the same AA level (and filter results) as the solid part. Quite noticable with hair renders. - Vector buffer support & preliminary vector-blur Node Using the "Render Layer" panel "Vector" pass button, the motion vectors per pixel are calculated and stored. Accessible via the Compositor. The vector-blur node is horrible btw! It just uses the length of the vector to apply a filter like with current (z)blur. I'm committing it anyway, I'll experiment with it further, and who knows some surprise code shows up!

Four-in-one commit: (NOTE: new include dependency in Render module, might need MSVC update! It has to include the imbuf/intern/openexr/ directory in search path) -> New Composite node: "Hue Saturation". Works like the former 'post process' menu. There's no gamma, brightness or multiply needed in this node, for that the Curves Node functions better. -> Enabled Toolbox in Node editor This now also replaces the SHIFT+A for adding nodes. The nodes are automatically added to the menus, using the 'class' category from the type definition. Current classes are (compositor examples): Inputs: RenderResult, Image Outputs: Composite, Viewer Color Ops: RGB Curves, Mix, Hue Saturation, AlphaOver Vector Ops: Normal, Vector Curves, Map Value Filters: Filter, Blur, VectorBlur Convertors: ColorRamp, RGBtoBW, Separate RGBA, Separate HSVA, Set Alpha Generators: RGB, Value, Time Groups: the list of custom defined nodes -> OpenEXR tile saving support Created an API for for saving tile-based Images with an unlimited amount of layers/channels. I've tested it for 'render result' now, with the idea that this can (optionally) replace the current inserting of tiles in the main result buffers. Especially with a lot of layers, the used memory for these buffers can easily go into the 100s of megs. Two other advantages: - all 'render result' layers can be saved entirely in a single file, for later use in compositing, also for animation output. - on each render, per scene, a unique temp file can be stored, allowing to re-use these temp files on starting Blender or loading files, showing the last result of a render command. The option is currently disabled, needs more work... but I had to commit this because of the rest of the work I did! -> Bug fix The Image node didn't call an execute event when browsing another image.

Orange: enabled compositing in render pipeline. - New Node "Composite" is output node that puts composited result back in render pipeline. - This then also displays in the render window while editing - But, only with Scene buttons option "Do Compositor" set - Then, just press F12 or render anims to see the magic! For clarity, the former 'Output" node is renamed to "Viewer".

A couple of compositing nodes: * Combine RGBA Basically the opposite of separate RGBA, brings 4 value channels into a single RGBA image). Has interesting possibilities for reordering channels, when used with separate RGBA! * Dilate/Erode Originally written by Brecht van Lommel, with some minor modifications and tweaking by myself. Positive distances dilate, negative distances erode. * I also added the 'value' field to the hue/saturation node. Minimal extra cost, and can be handy.

== Shader nodes == * Geometry node: Front/back output This is used as a mask for determining whether you're looking at the front side or back side of a mesh, useful for blending materials, my practical need was giving different materials to the pages of a magazine: http://mke3.net/blender/etc/frontback-h264.mov Give 1.0 if it's the front side, and 0.0 if it's the back side. * Extended material node This is the same as the material node, but gives more available inputs and outputs, (basically just connecting up more of ShadeInput and ShadeResult to the node).

It's been possible to invert previously by adding a mix node and subtracting the input from 1.0, but it's not the best way of doing it.

Using subtract for inverting is easily mixed up with other nodes in which you are actually subtracting, not inverting, and looks very similar to all the other mix nodes that usually litter a comp tree. - has options to invert the RGB channels, the Alpha channel, or both. This saves adding lots of extra nodes (separate RGBA, subtract, set alpha) when you want to do something simple like invert an alpha channel. I'd like to add this option to other nodes too. There's also a shader node version too. * Also a few fixes that I committed ages ago, but seems to have been overwritten in Bob's node refactor: - adding new compbufs to the set alpha and alphaover nodes when you have only one noodle connected to the lower input - making the fac value on RGB curves still work when there's nothing connected to it

Crop Compositing Node: This commit adds a new node, crop, to the compositor. This node can be used to crop input image. It has two modes of operation. It can either crop image size (Crop Image Size option) or crop while retaining original size of the image. This latter mode can be used to preview the crop. Use X1, Y1, X2, Y2 controls to manage the area to be cropped. Note that I added a check for image preview min and max values to node_update. This is because it could give inappropriate values in certain cases when Crop Image Size option was toggled (values such as x1=0, y1=0, x2=60, y2=0 would result in eternal loop due to bad min and max (min bigger than max!)). The check makes sure that min and max values are always valid.

Directional Blur Node Directional Blur node allows the users to do various blur operations on the input image. It essentially offers three different kind of ways of blurring in one node. It is possible to blur using a certain direction, spin and zoom. These three ways can be used in conjunction. The node contains following controls: *Iterations, Wrap *Center: X, Y *Distance, Angle *Spin *Zoom Iterations is used to determine the smoothness of the result. The more iterations, the smoother result. Low values are good for preview. Wrap means that the image is wrapped as if it was tiled on both x and y directions. To see better what this means, try it with spin for instance. Center values (X and Y) determine the location which is used as a pivot point for the operations. It is center (0.5) of the image by default. Distance and angle are used to adjust directional blur. The result can be described as a sweep that varies based on given distance (bigger distance, longer sweep) and angle. Angle is given in degrees. Spin produces rotating blur based on given angle. Yet again it is in degrees. Also negative values work. Zoom causes the image to be zoomed towards set center point (Center values). Thanks to Alfredo de Greef (eeshlo) for contribution. Possible development ideas: *Make an algorithm to extend image in case spin is used. Extend would temporarily change the size of the canvas of the input image. Canvas would be filled based on colors on the edges of the input image. After the blur operation has been done, the image would be cropped back to normal size. The advantage of this would be nicer result of spin (no problems with image size) on a computational cost. *Make values animatable. This is something that is better solved on more general level. ("everything is animatable" paradigm) *Provide an option to calculate automatic value for iterations. A good value that produces a smooth result could be calculated based on direction deltas. This would be useful in conjuction of animatable values.

Bilateral Blur Node Bilateral Blur node allows the user to blur images while retaining their sharp edges. Blurring can be controlled by following controls: *Iterations *Color Sigma *Space Sigma Also image input to blur and a determinator image is provided. The node produces a blurred image as its output. The more iterations are provided, the smoother the result. Use color and space sigmas to control the amount of blur. One way to use the determinator input is to feed a mix (add) of Z and normal passes to it. Examples of usage: Ambient Occlusion smoothing - http://wiki.blender.org/index.php/Image:Bilateral_blur_example_01.blend Blurry Refraction - http://wiki.blender.org/index.php/Image:Bilateral_blur_example_02.blend Smoothed shadows and smoothed Ambient Occlusion combined - http://wiki.blender.org/index.php/Image:Bilateral_blur_example_03.blend If you check out the examples, render the image and alter the values to see how they affect. More information about the algorithm can be found at http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPIES/MANDUCHI1/Bilateral_Filtering.html . Thanks to Vilem Novak for contributing the patch.

int ntreeCompositTagAnimated(struct bNodeTree *ntree);
Compositing workflow upgrade; You now can set a Preview panel in the Image window, to define a sub-rect of an image to be processed. Works like the preview in 3D Window. Just press SHIFT+P to get it activated. Very nice speedup! This is how it works: - The compositor still uses the scene image size (including % setting) for Viewer or Composite output size - If a preview exists, it calculates the cropped rect from its position in the Image window, and stores that in the Scene render data - On composite execute, it copies only this part from the 'generator nodes', right now Images or Render Results. That makes the entire composite tree only using small rects, so it will execute fast. - Also the render window will only display the cropped rect, and on F12 only the cropped part is being executed - On rendering in background mode, the cropping is ignored though. Usability notes: - translating or zooming view will automatically invoke a recalculation - if you zoom in on details, the calculated rect will even become smaller - only one Imagewindow can have this Preview Panel, to prevent conflicts of what the cropped area should be. Compositing is on Scene level, not local per image window. (Note; 3D Previews are local per window!) - Closing the preview panel will invoke a full-size recalculation - All passes/layers from rendering are nicely cropped, including Z and vectors. The work to make the compositor do cropping was simple, but getting the Image window displaying correctly and get all events OK was a lot of work... indeed, we need to refactor Image Window usage once. Sorry for making the mess even bigger now. :) I've tried not to interfere with UV edit or Paint though... only when you're in compositing mode the panel will work. BUG fix: 3D Preview render didn't work when multiple layers were set in the current scene.

void ntreeCompositForceHidden(struct bNodeTree *ntree);
Orange: made Compositing more interactive. It now has an event based system tracking changes in nodes, making sure only these nodes and the ones that depend, are executed. Further the 'time cursor' now counts down to indicate which node is being done. Also: you now can disable the "use nodes" button in the header, edit all changes, and when you press that button again it nicely executes the changes. Still on the todo: - make compositing threaded - find a way to nicely exit compositing on input events... so the UI keeps being responsive - idea; a 'percentage' menu in header to enforce calculations on smaller images temporally

(yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

void free_compbuf(struct CompBuf *cbuf); /* internal...*/
Changed node type definitions to use a dynamic list. This will allow python or plugin defined nodes to work as well. (And fixes compile issues with MSVC in yesterdays commit for nodes) Code provided by Nathan L. Fixes in his code: - free_nodesystem() was called too late (after guarded alloc was closed) - free_nodesystem() was freeing nodes that were not malloced even - free_nodesystem was using free, not freeN :) - the typedefs needed to be malloced yes, to allow duplicate nodes like group but also for dynamic nodes.

Orange: - Sunday merger with bf-blender - Foundations for new Node editor in Blender, generic framework that can be used for Material/Texture, Compositing, Logic or maybe even Sequencer. Note: this doesn't do anything yet, nor save! Is just to get this nice in CVS now. :)
