Let's bring Houdini proceduralism to RenderMan!

What is hGeoPatterns

hGeoPatterns is a collection of RenderMan plugins for sampling any Houdini compatible geometry. This project is a mixture of RIS and HDK functionality to make operations like sampling and reading arbitrary Houdini Geometry Data in RenderMan shading networks. Similar to familiar xyzdist(), prim_attribute(), nearpoints() VEX functions. OSL shaders, headers and VOP definitions are included to make shader authoring easy.

Whats NEW

:star: Added volumeSample for both VDB and native Houdini volumes.
