Pixar has released its new RIS architecture for raytracing complex scenes.
Fast raytracing for scenes with heavy geometry
RIS, available alongside RenderMan¡¯s traditional REYES architecture, is a ¡°highly optimised mode for rendering GI¡± particularly scenes with ¡°heavy geometry, hair, volumes, and irradiance ¡ in a single pass¡±.
The RIS architecture incorporates a range of algorithms, including both a unidirectional path tracer and a bidirectional path tracer with progressive photon mapping.
It comes with a progressive renderer, for rapid visual feedback on a scene.
