160d8f6c0c Cycles: fix cuda assertion that could be triggerd sometimes, when trying to 
tonemap an empty image.

47fb31404f Cycles: preview passes setting to set the max number of passes to render in 
the viewport working now, set to 0 for unlimited (well, actually 2147483647).

bae896691a Cycles: 
* Add alpha pass output, to use set Transparent option in Film panel.
* Add Holdout closure (OSL terminology), this is like the Sky option in the
  internal renderer, objects with this closure show the background / zero
  alpha.
* Add option to use Gaussian instead of Box pixel filter in the UI.
* Remove camera response curves for now, they don't really belong here in
  the pipeline, should be moved to compositor.

* Output full float values for rendering now, previously was only byte precision.
* Add a patch from Thomas to get a preview passes option, but still disabled
  because it isn't quite working right yet.
* CUDA: don't compile shader graph evaluation inline.
* Convert tabs to spaces in python files.

48b4de3152 Cycles: 
* auto/fixed threads option is used now, patch by Thomas.
* remove unused CUDA_LIBRARIES, library is dynamically loaded
* fix mesh XML export operator for API update

f7b9c85871 Cycles: fix some invalid memory access problems found by running the windows build in debug mode. 2011-08-21 10:32:15 +00:00

360fcd73fe Cycles: 
* add some (disabled) test code for using OpenImageIO in imbuf
* link cycles, openimageio and boost into blender instead of a shared library
* some cmakefile changes to simplify the code and follow conventions better
* this may solve running cycles problems on windows XP, or give a different
  and hopefully more useful error message

922bb24865 Cycles: color space control for image/environment texture nodes. Ideally would 
be automated but need to think about how to do this, not so simply in a node
system. But guideline for now is, for color textures set to sRGB, for things like
bump or roughness map, set to Linear.

da376e0237 Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later. 
Cycles uses code from some great open source projects, many thanks them:

* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
http://web.maths.unsw.edu.au/~fkuo/sobol/
* Film response functions from:
