Vfxgal is a geometric algorithms library for the VFX industry. It contains a very fast and robust voronoi fracturer, as well as several other geometric algorithms (plane-clip, hull-clip etc). Vfxgal comes with Houdini11 bindings but has been written in such a way that minimal work is needed to bind to other frameworks.

StudioNEST Brigks is a collection of kinematic solvers for Autodesk Softimage.
With StudioNEST Brigks you can build very efficient rigs that don’t require to setup overly complex object hierarchies. Since the source code of the kinematics solvers is provided, implementations of matching kinematic solvers can be achieved for other packages as well as standalone applications.
