2020-02-12	Cleanup: Fix build warnings from OSL shader compilation	Ray Molenkamp
	There were to copies of stdosl.h one from stock OSL and one in the cycles tree augmented with cycles specific closures. moved the cycles ones to stdcycles.h and copied the stock stdosl.h and accompanying headers from the OSL shader folder. for further details see D6812.

2018-03-10	Cycles: switch to squared roughness convention for all nodes.	Brecht Van Lommel
	This was already done for the Principled BSDF to be compatible with typical baked roughness maps in PBR workflows.
2016-06-23	Cycles: Add multi-scattering, energy-conserving GGX as an option to the ↵	Lukas Stockner
	Glossy, Anisotropic and Glass BSDFs This commit adds a new distribution to the Glossy, Anisotropic and Glass BSDFs that implements the multiple-scattering microfacet model described in the paper "Multiple-Scattering Microfacet BSDFs with the Smith Model". Essentially, the improvement is that unlike classical GGX, which only models single scattering and assumes the contribution of multiple bounces to be zero, this new model performs a random walk on the microsurface until the ray leaves it again, which ensures perfect energy conservation. In practise, this means that the "darkening problem" - GGX materials becoming darker with increasing roughness - is solved in a physically correct and efficient way. The downside of this model is that it has no (known) analytic expression for evalation. However, it can be evaluated stochastically, and although the correct PDF isn't known either, the properties of MIS and the balance heuristic guarantee an unbiased result at the cost of slightly higher noise.

2016-06-12	Cycles: make shader node enums consistently lower case, update OSL shaders ↵	Brecht Van Lommel
	accordingly.
2014-12-25	Cleanup: Fix Cycles Apache header.	Thomas Dinges
	This was already mixed a bit, but the dot belongs there.
2014-06-14	Cycles: glossy and anisotropic BSDF changes	Brecht Van Lommel
	* Anisotropic BSDF now supports GGX and Beckmann distributions, Ward has been removed because other distributions are superior. * GGX is now the default distribution for all glossy and anisotropic nodes, since it looks good, has low noise and is fast to evaluate. * Ashikhmin-Shirley is now available in the Glossy BSDF.

2012-12-11	OSL Shader Files:	Thomas Dinges
	* Simplify default color values, where each component was the same. * Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.
2012-11-03	Cycles OSL: refactoring and fixes	Brecht Van Lommel
	* Moved kernel/osl/nodes to kernel/shaders * Renamed standard attributes to use geom:, particle:, object: prefixes * Update stdosl.h to properly reflect the closures we support * Fix the wrong stdosl.h being used for building shaders * Add geom:numpolyvertices, geom:trianglevertices, geom:polyvertices attributes
