The goal of Partio is to provide a unified interface akin to unified image libraries that makes it easier to load, save, and manipulate particle files.
* Supports Houdini's GEO and BGEO, Maya's PDB and PDA, RenderMan's PTC
* Arbitrary back end in-memory/cached formats can be supported from a single interface
* A Python API for easy scripting of particle manipulation
* A C++ API for high performance particle manipulation
* Nearest Neighbor Lookups for density estimation, Voronoi computation, etc.
