d0ffbeec73 Cycles OpenCL: a few fixes to get things compiling after kernel changes,
for Apple OpenCL on OS X 10.8 and simple AO render.

Also environment variable CYCLES_OPENCL_TEST can now be set to CPU, GPU,
ACCELERATOR, DEFAULT or ALL values to test particuler devices.

d236b4d60f Cycles bump node: change the Strength value to work better, previously it would
give results that were either too weak or too strong, this makes it give more
predictable results. The downside is that it breaks backwards compatibility but
the previous behavior was almost broken.

01dc4b034f Cycles / Tile Rendering:
* Code refactor of tile ordering to simplify the code and avoid some branching. 
* Changed the Center method, so it really follows center -> corners, instead of the BI method, which was confusing sometimes.

Patch by Stuart Broadfoot, with small tweaks by me, to only enable it on sm_20 and above.

3e763d7e4d Fix #35246: cycles has no simple way to combine bump and normal mapping. Now
the Bump node has a Normal input, so you can chain it after a Normal Map node.
Note that normal mapping always has to be done first because it is tied to the
particular mesh surface and tangents.

273f5226da Fix #35160: cycles was rendering glossy BSDF's with zero roughness too rough
after a bugfix for precision issues with low roughness. Now it renders them as
perfectly sharp which avoids the problematic calculations rather than increasing
the roughness.

428debd9c8 Fix for "new" Cycles handling of textures, UI code assumed all texture users use "texture" as prop name, but at least WeightVG modifiers do not.
Fixed by adding a "texture_user_property" member to spacebuts' context, and using it to get the prop identifier in ui script.

Thanks to Brecht for its advice!

48a6fe86ca Fix #34172: cycles BVH build crashing in some rare circumstances on 32 bit linux.
The problem was (again) the x86 extended precision float register being used for
one float value while the other was rounded to lower precision. This caused the
strictly weak order requirement for std::sort to be broken.

18b1ab1598 Fix #34714: cycles viewport render would restart when minimizing and unminimizing
a maximized Blender window in Ubuntu Unity. The window size would slightly change
as part of the unminimize effect.

Now cycles waits 0.2 seconds before restarting rendering after a viewport resize,
also a bit less flickery when changing the 3d view size in Blender itself.

dee74c299f Attempt to fix #35041 and #34725: cycles crash with OSL and both a 3D viewport
and preview running at the same time.

It seems there's something in OSL/LLVM that's not thread safe, but I couldn't
figure out what exactly. Now all renders share the same OSL ShadingSystem which
should avoid the problem.

ed1a08382f Cycles: code refactoring to deduplicate the various BVH traversal variations.
Now there is a single BVH traversal code with #ifdefs for various features.
At runtime it will then select the appropriate variation to use depending if
instancing, hair or motion blur is in use.

This makes scenes without hair render a bit faster, especially after the
minimum width feature was added. It's not the most beautiful code, but we can't
use c++ templates and there were already 4 copies, adding 4 more to handle the
hair case separately would be too much.

c9fc3874d6 Cycles: when render layers have per layer number of samples set, the Sampling
panel now has an option to specify how to use them. There's three options:

* Use: render layer samples override scene samples
* Bounded: bound render layer samples by scene samples
* Ignore: ignore render layer sample settings

638b084f82 Cycles Hair: Strand Minimum Pixel Size
Code is added to restrict the pixel size of strands in cycles. It works best with ribbon primitives and a preset for these is included. It uses distance dependent expansion of the strands and then stochastic strand removal to give a fading. To prevent a slowdown for triangle mesh objects in the BVH an extra visibility flag has been added. It is also only applied for camera rays.

The strand width settings are also changed, so that the particle size is not included in the width calculation. Instead there is a separate particle system parameter for width scaling.

549fa84afa Fix #34948, bug in Cycles node groups. The proxy node maps used to identify external connections of node group nodes were having name clashes with input/output sockets of the same name, leading to invalid cyclic connections in the cycles shader graph that were subsequently removed (prints warnings in terminal). Solution is to use two separate maps for inputs and outputs so group node sockets can safely use the same identifier. 2013-04-11 09:16:36 +00:00

e802efb7af Fix #34740: cycles rendering issue mixing glossy/glass BSDF's with zero or very

Problem was bad float precision due to low roughness, which caused the pdf for
