3abef3a2e6 Cycles OSL: some build system tweaks to avoid global includes and definitions,
which ensures there is no conflict with other libraries, and avoids full rebuild
when toggling OSL on/off.

9f8070d047 code cleanup:
- define array sizes for functions that take vectors.
- quiet some -Wshadow warnings.
- some copy/paste error in readfile.c made it set the same particle recalc flag twice.

Thanks to Brecht for pointing out the solution.

497ea5f306 Fix #32912: cycles crash with dead particles, actual crash was caused by an
inconsistency in the particle system code, using <= and <. Also tightened up
checks on cycles side to avoid other potential crashes.

d396bf3546 Fix for OSL compile errors.
1) object_fetch_transform_motion omits the per-object motion blur test (r51394), must use object_fetch_transform_motion_test.
2) KernelCamera.ndctoworld has been removed (r51402), do transform invert directly.

6915394a3b Attempts to fix CUDA issues on sm 2.0 cards, still no luck getting motion blur
working, but this should make it not crash.

Also fix for wrong shutter time, should have been shorter.

4ad103cedd Fix cycles motion blur not working correct with shutter time > 2.0. The soft
limit is 2.0, and anything beyond that is extrapolation which might not work
so well but is still allowed.

d08b06f773 Cycles: motion blur is now curved and passes exactly through the midpoint.
Previously it would only interpolate between the previous and next frame,
which meant it might not hit the current frame position.

0551aa14bb Fix for OSL 'background' attributes (attributes that are not associated to a particular object). Atm this is only the 'ray_length' attribute.
Background attributes are used as fallback in two cases:
1) Non-object light samples (e.g. lamp shaders)
2) Fallback if no implicit object attribute can be found

536d9fec80 code cleanup:
- move object_iterators.c --> view3d_iterators. (ED_object.h had to include ED_view3d.h which isn't so nice)
- move projection functions from view3d_view.c --> view3d_project.c (view3d_view was becoming a mishmash of utility functions and operators).
- some some cmake includes as system-includes.

617cdb4642 Fix for second bug reported in #32846: Particle emitters are still shown for secondary instances with "show emitter" disabled. This requires checking the duplicator visibility on dupli objects themselves after generating the dupli-list.
The emitter visibility option is messy design, it makes such checks unnecessarily complicated. A better approach would be to allow non-mesh objects to carry particle data, these objects would just be invisible anyway without having to care about extra settings. However, this conflicts with the simplistic particle design of "owner is the emitter" ...

9be4c94204 Cycles: non-camera viewport render border support
This makes it possible to do a border render inside a viewport even
when not looking through the camera.

Render border could be defined by Ctrl-B shortcut (works for both
camera render border and viewport render border).

Camera render border could still be defined using Shift-B (so no
muscule memory would be broken). Currently used a special flag of
operator to do this, otherwise you'll need to either two operators
with different poll callback or it could go into conflict with a
border zoom,

Border render of a viewport could be enabled/disabled in View
panel using "Render Border" option.

af537c283c Fix for (camera) motion blur changes in Cycles OSL. Compilation was broken due to changed object transform functions. Also added a few missing renderer service implementations for matrix callbacks. 2012-10-16 10:59:35 +00:00

7521ce083d Cycles: object motion blur enabled, so in addition to camera motion, moving
objects in the scene will also cause motion blur.

This change does come with a bit of a slow down to the CPU rendering kernel even
with motion blur disabled, due to extra overhead in handling of object matrices.
It's a few percentages on simpler scenes, not so noticeable on more complex ones.
With motion blur enabled rendering is of course also slower as would be expected,
though from testing especially GPU rendering handles it quite well.

This does not support motion blur from deforming objects yet, only translation,
scale and rotation. Deformation blur is probably for another release.

3b88a29abf Cycles: progressive refine option
Just makes progressive refine :)

This means the whole image would be refined gradually using as much
threads as it's set in performance settings. Having enough tiles is
required to have this option working as it's expected.

Technically it's implemented by repeatedly computing next sample for
all the tiles before switching to next sample.

This works around 7-12% slower than regular tile-based rendering, so
use this option only if you really need it.

This commit also fixes progressive update of image when Save Buffers
option is enabled.

And one more thing this commit fixes is handling display buffer with
Save Buffers option enabled. If this option is enabled image buffer
wouldn't have neither byte nor float buffer until image is fully
rendered which could backfire in missing image while rendering in
cases color management cache became full.

This issue solved by allocating byte buffer for image buffer from
tile update callback.

Patch was reviewed by Brecht. He also made some minor edits to
original version to patch. Thanks, man!

fe09b24e86 Cycles: per-BSDF normal input and new Bump node.
Each BSDF node now has a Normal input, which can be used to set a custom normal
for the BSDF, for example if you want to have only bump on one of the layers in
a multilayer material.

The Bump node can be used to generate a normal from a scalar value, the same as
what happens when you connect a scalar value to the displacement output.

Documentation has been updated with the latest changes:
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes

Patch by Agustin Benavidez, some implementation tweaks by me.

f0a9b66469 Cycles: Anisotropic BSDF enabled, with tangents now computed from the active UV map.
It's using the Ward BSDF currently, which has some energy loss so might be a bit
dark. More/better BSDF options can be implemented later.

Patch by Mike Farnsworth, some modifications by me. Currently it's not possible yet
to set a custom tangent, that will follow as part of per-bsdf normals patch.

78978dcd80 Fix for a case of 'static initialization fiasco' with OSL closure variables. The parameter lists are using OIIO::TypeDesc static standards, which are also static variables. With static OSL libraries these are not initialized when the closure parameter lists are initialized, so OSL rejects the closure types.
Putting static initialization into functions works just as well, but ensures the OIIO::TypeDesc access is delayed until initialization is complete.

fedc8e1722 Cycles: add "From Dupli" option for texture coordinate node. This gets the
Generated and UV coordinates from the duplicator of instance instead of the
object itself.

This was used in e.g. Big Buck Bunny for texturing instanced feathers with
a UV map on the bird. Many files changed, mainly to do some refactoring to
get rid of G.rendering global in duplilist code.
