f99343d3b8 Cycles: Render Passes 
Currently supported passes:
* Combined, Z, Normal, Object Index, Material Index, Emission, Environment,
  Diffuse/Glossy/Transmission x Direct/Indirect/Color

Not supported yet:
* UV, Vector, Mist

Only enabled for CPU devices at the moment, will do GPU tweaks tommorrow,
also for environment importance sampling.

fc42a6185d Cycles: 
* Fix object scaling update issue with interactive rendering + static BVH.
* Fix negative scaling issue with static BVH.
* Fix #29217: excessive fireflies in first sample.

cdee3435c6 Cycles: internal changes that should have no effect on user level yet, added 
shader flags for various purposes, and some code for light types other than
points.

376aede7a6 Cycles: fix crash deleting emitting objects. 2011-09-16 12:59:22 +00:00

ebc653463d Cycles: 
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.

And a bunch of incomplete and still disabled code mostly related to closure
sampling.

67030aaf84 Cycles: optimizations for instances in scene updates before render starts, 
should load a non-trivial mesh instanced many times quite a bit faster now.

df625253ac Cycles: 
* Add max diffuse/glossy/transmission bounces
* Add separate min/max for transparent depth
* Updated/added some presets that use these options
* Add ray visibility options for objects, to hide them from
  camera/diffuse/glossy/transmission/shadow rays
* Is singular ray output for light path node

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:
