GPUBuffer rendering is now done using vertex buffers.
Vertex arrays are completely removed from GL 3.2 core profile, so we'll
have to do this change at some point anyway.
This commit, though big, is not modifying blender in any way. Use should
be exactly as if the vetex buffer option is constantly on.
Implements "Auto-offset" (called "insert offset" in code) feature for Node Editor, developed during and after LSOC :)
Idea and sponsoring by Sebastian König, blendFX, Mathias Eimann, Mikavaa, Knick Design
When you drop a node with at least one input and one output socket onto a an existing connection between two nodes, Auto-offset will, depending on the direction setting, automatically and animated move the left or right and all of its following nodes away to make room for the new node.
The direction for offsetting can be toggled while you are moving the node by pressing „T“.
The auto-offset is enabled by default but can be disabled in the header of the node-editor. The offset margin can be changed in the editing section of the User Preferences.
Thanks a lot to the sponsors, and especially to Sebastian who helped *a lot* with this. That's how users can help developing Blender!
This commit contains all the remained parts needed for initial integration of
OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU
backends which works in the following way:
- When SubSurf modifier is the last in the modifiers stack then GPU pipeline
of OpenSubdiv is used, making viewport performance as fast as possible.
This also requires graphscard with GLSL 1.5 support. If this requirement is
not met, then no GPU pipeline is used at all.
- If SubSurf is not a last modifier or if DerivesMesh is being evaluated for
rendering then CPU limit evaluation API from OpenSubdiv is used. This only
replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG
structures exactly the same as they used to be for ages now.
This integration is fully covered with ifdef and not enabled by default
because there are several TODOs to be solved first:
- Face varying data interpolation is not really cleanly implemented for GPU
in OpenSubdiv 3.0. It is also not implemented for limit evaluation API.
This basically means we'll have really hard time supporting UVs.
- Limit evaluation only works with adaptivly subdivided meshes so far, which
basically means all the points of CCG are pushed to the limit. This gives
different result from old code.
- There are some serious optimizations possible on the topology refiner
creation, which would speed up initial OpenSubdiv mesh creation.
- There are some hardcoded asumptions in the GPU and DerivedMesh areas which
could be generalized.
That's something where Antony and Campbell can help, making it so the code
is structured in a way which is reusable by all planned viewport projects.
- There are also some workarounds in the dependency graph to make sure OpenGL
buffers are only freed from the main thread.
Those who'll be wanting to make experiments with this code should grab dev
branch (NOT master) from
https://github.com/Nazg-Gul/OpenSubdiv/tree/dev
There are some patches applied in there which we're working on on getting
into upstream.
team.
There are 3 options here:
1) Keep range (previous behaviour)
2) Seconds - allows a specified offset in seconds around current frame
3) keyframes - zoom to include a number of keyframes around the cursor
Options 2 and 3 have their own properties to tweak the behaviour and all
options can be found in User Preferences->Interface under the 2D
viewports section.
Number 3 will probably need some refinement so commiting here for the
hwoozeberry team to test first.
Our current keymap doesn't give us enough room to make such changes in
the event system. To fix small issues caused by this, we would need to do
drastic changes in Blender's keymaps and internal handling. It was worth
a try, but it didn't work.
I can write down a more descriptive statement in a few days, but for now
I need a break of this stuff.

Short description:
With this we can distinguish between holding and tabbing a key. Useful
is this if we want to assign to operators to a single shortcut. If two
operators are assigned to one shortcut, we call this a sticky key.
More info is accessible through the design task and the diff.
A few people that were involved with this:
* Sean Olson for stressing me with this burden ;) - It is his enthusiasm
that pushed me forward to get this done
* Campbell and Antony for the code and design review

make this possible
A big "Thank You" for you all!
OpenGL is detected:
Hoping to decrease the frequency of by far one of the most frequent bug
reports by windows users.
There is some reorganization of the GHOST API to allow easy addition of
further OpenGL options in the future. The change is not propagated too
deep to keep the size of the patch managable. We might reorganize things
here later.
For OpenGL we do two checks here:
One is a combination of GDI generic renderer or vendor microsoft
corporation and OpenGL version 1.1. This means the system does not
use GPU acceleration at all. We warn user to install a graphics
driver and of cases where this might happen (remote connection, using
blender through virtual machine)
The other one just checks if OpenGL version is less than 1.4 (we can
easily change that in the future of course) and warns that it is
deprecated.
Both cases will still let blender startup correctly but users should now
have a clear idea of the system being unsupported.
A user preference flag is provided to turn the warning off.
Now stop posting those bug reports without installing a driver first -
please?
* Rename "emboss" to "widget_emboss"
* Remove duplicated UI_GetThemeColor4ubv function
I made sure version bump and Save User Settings are working correctly ;P
This adds a theme option for the embossing of UI widgets. By doing this users have much greater flexibility for creating nice themes. Previously many themes (particularly dark ones) looked quite bad due to the very obvious emboss. This made simpler, flat-style themes very challenging.

This commit adds a confirm threshold property to pie menus.
Basically, this will confirm the pie menu automatically when
the distance from the center of the pie exceeds that threshold without
a need to release the pie button.
The confirm threshold will only work if it is larger than the pie
threshold.
The confirmation actually occur when the mouse stops moving, to
allow multiple pie menus to be better linked together, (see below)
This functionality also facilitates the ability for chained pie menus by
dragging. Basically, a pie menu item can be a call_menu_pie operator and
the new pie menu will still use the original pie menu release event for
confirmation. This should allow for quick, gesture based navigation in
pie menu hierarchies (going back in the hierarchy is still not supported
though)
There will be a demonstration pie in the official add-on soon
On 4k devices the default pixel size leads to tiny OpenGL drawing
that is hardly usable without doubling the DPI. The retina system
on OSX aims to alleviate this problem by introducing a general 2x
pixel size.
No equivalent feature exists on other platforms so far. However,
to emulate the effect this patch introduces a "virtual" pixel size
factor for OpenGL drawing.
Note that the user currently has to enable this manually by selecting
the "Virtual Pixel Mode" in the user preferences (defaults to native).
All windows of a Blender instance share the same virtual pixel size as well.
It may be possible to handle this on a per-window basis and automate
the selection somewhat (if enabled by the user), so working with
multiple screens becomes more convenient, but technical limitations
make this a bit difficult (on X11 with nvidia drivers the actual screen size
is not reported correctly).

This commit merges the code in the pie-menu branch.
As per decisions taken the last few days, there are no pie menus
included and there will be an official add-on including overrides of
some keys with pie menus. However, people will now be able to use the
new code in python.

Thanks:
Campbell Barton, Dalai Felinto and Ton Roosendaal for the code review
and design comments
Jonathan Williamson, Pawel Lyczkowski, Pablo Vazquez among others for
suggestions during the development.
Special Thanks to Sean Olson, for his support, suggestions, testing and
merciless bugging so that I would finish the pie menu code. Without him
we wouldn't be here. Also to the rest of the developers of the original
python add-on, Patrick Moore and Dan Eicher and finally to Matt Ebb, who
did the research and first implementation and whose code I used to get
started.
This patch creates an interface for selection mechanisms in opengl. This
makes it possible to switch between occlusion query based or select
rendermode based selection transparently.
This is really useful on graphics drivers that do not accelerate the
select rendermode path (some ATI cards are notorious for this, and the
new path is used by default there), since occlusion queries are always
hardware accelerated due to their use in games.
The option can be found under system - selection. Auto just enables
occlusion queries for ATI users while the rest of the options enforce
one of the two methods always.
There is just one known change, previous code enforced nearest bone to
always get selected, even when mouse selecting near the same position, I
couldn't replicate the behaviour though.
patch by me with edits and review by Campbell.
Thanks!
Simply add an option to render settings to save an EXR cache,
just when the render is finished. Also changed RE_ReadRenderResult() to read
cache instead of temp sample files (those are fully volatile now anyway).
Path to save cached render results is an UserPreferences setting.
Also added 'Reload render' feature to the Image Editor (so one can now re-open a blend,
and in an Image Editor hit ctrl-R to (try to) reload last render from cache).

After some discussion it seems both are valid defaults but useful for
very different purposes.
- 'free' lets you explore the scene with full 6dof (like fly mode)
- 'orbit' is closer to typical mouse view orbit, constraining to orbiting about a central location.
This doesn't effect orbit/pan which are available with modifier keys.
This aligns the User Preferences > File > Author field and label horizontally, saving space and making it more consistent with author text fields within the same section.
This commit adjusts the spacing of the items in User Preferences > System. The spacing is adjusted via separators between each section of options. This better differentiates between groups of options. It also removes a few extra separators for more consistency.
This is a addtion to the dynamic fly mode.
It behaves as the first person navigation system available in most 3d world games nowadays.
You can alternate between the old mode (Fly) and the new mode (Walk) in User Preferences > Inputs

Shortcuts:
----------
WASD (hold) - Move forward/backward and straft left/right
QE (hold) - Move up and down
Tab - Alternate between Walk and Fly modes
Shift (hold) - Speed up movement
Alt (hold) - Slow down movement
Space or MMB - Teleport
V - Jump
+/- or mouse wheel - speed increase/decrease speed for this Blender session
User Preferences Options:
-------------------------
Navigation Mode - fly/walk navigation systems (fly is the old, walk is the new, next options are for walk mode only)
Gravity - alternate between free navigation and walk with gravity modes
Mouse Sensitivity - sensitivity factor to mouse influence to look around
Teleport Duration - how long the teleport lasts
Camera Height - camera height to use in gravity mode
Jump Height - maximum jump speed in m/s
Move Speed - base move speed in m/s
Boost Factor - multiplication factor when running or going slow (1/boost)
Development Notes:
------------------
* The initial code was based on view3d_fly.c.
* The NDoF code was not touched, so it most likely is not working.
Pending Issues:
---------------
* Draw in the UI the shortcut options, and current values (e.g., Mode: Fly/Walk)
(we need a proper API for that)
* OSX seems to present issues if we re-center the mouse every time. We implemented a workaround for that, but a real fix would be welcome.

- move addon refresh button into header
- uilist, use icon for sorting by name (gives more room for name, icon is used in fileselector for same purpose).
- rename orderby to sort in rna and flag names.
- simplify BKE_nurb_handle_calc_simple
The addons panel draw function calls addon_utils.modules() which in turn retrieves a list of fake modules from the script paths every time. This can become costly when network paths are included for
addons. Solution is to put the scanning process into a dedicated "refresh" function and disable it in frequently called draw and filter functions, i.e. in these cases the cached addons_fake_modules list
will be used instead.
Note that this may lead to invalid addon lists if script paths are changed (which is not working 100% without restart anyway according to Campbell). For this there is now a "Refresh" operator button in
the addons preferences. If necessary and feasible such forced refreshes can be added later too.
Notes:
* Made those edits by full checking of py files, so I should have spoted most needed edits, yet it remains quite probable I missed a few ones, we'll fix if/when someone notice it...
* Also made some cleanup "on the road"!
