Rendering Caches
The Pixar RenderMan interconnection is a fundamental building block in our uniform geometry pipeline, as a
geometry cache can be used directly as a procedural primitive in RenderMan (see Figure
5-3
), thus removing the need
for geometry in RIB (RenderMan Interface Bytestream Protocol) files. Cache files are smaller and more flexible than
RIB files. They can also be up to 10x faster to render than RIB files due to fast deserialization and coherent data layout.
