Brecht Van Lommel	efe4ea284a	Cycles: ... * Fix broken compile of test app. * Fix some warnings compiling with gcc for 32 bit. * More tweaks to avoid extended precision issue from #29301.	2011-12-02 14:26:28 +00:00
Brecht Van Lommel	b6021462a8	Another possible fix for #29301: issue with BVH intersection, reorder code a ... bit so that it's more symmetric and resulting float ops are compiled the same way. Otherwise extended float precision being used in one place and not the other can make comparisons fail.	2011-11-30 16:29:26 +00:00
Brecht Van Lommel	6f73e351ee	Cycles: ... * Fix #29354: crash on branch file. Note that for best compatibility, you need to save your files with one of the latest branch builds, since not all version patching code was moved to trunk. * Rename "Cycles" to "Cycles Render" in info header menu. * Code tweaks to try to fix #29301. It's not a real solution though, I'm thinking cause is extended precision for floats on some cpu's, used in one case but not in the other, leading to bounding box intersection issue...	2011-11-21 16:28:19 +00:00
Brecht Van Lommel	e5f544dd92	Cycles: add transparent shadow support, i.e. shadows through Transparent BSDF ... shaders, enabled by default.	2011-10-16 17:54:43 +00:00
Brecht Van Lommel	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 Details here: http://wiki.blender.org/index.php/Dev:2.5/Source/Render/Cycles/LightPaths	2011-09-01 15:53:36 +00:00
Ton Roosendaal	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: http://www.cs.columbia.edu/CAVE/software/softlib/dorf.php	2011-04-27 11:58:34 +00:00
