Classes
class	RixBxdfFactory
class	RixBxdf
	The RixBxdf interface is a shading plugin responsible for creating a RixBxdf from the the ShadingContext and the set of connected patterns. More...
class	RixOpacity
	RixOpacity objects are obtained from the BxdfFactory::BeginOpacity when it determines conditions warrant non-trivial responses to either or both of Presence and Opacity queries. More...
class	RixVolumeIntegrator
	RixVolumeIntegrators can be obtained from the BxdfFactory at the hit point where a ray enters an interior region. More...
class	RixVolumeIntegrator::IntegratorDelegate
class	RixPostLighting

Enumeration Type Documentation

enum RixBXEvaluateDomain

Tells Integrator the domain over which lighting/connecting/merging needs to be done.

Reflect/Front = light samples are from the side the ray came from Transmit/Back = light samples are opposite the side the ray came from Outside = light samples are from the side the surface normal points into Inside = light samples are from the side the surface normal points away from The difference between Both and Volume is whether there's a cosine term (for surfaces) or not (for volumes).
