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.
⭐ Added volumeSample for both VDB and native Houdini volumes.
- XPU not supported
Thanks to SideFX for the extensive library and Pixar RenderMan for supporting the RixPattern interface.
