polyclipper

Library to clip polygons (in 2D) and polyhedra (in 3D) by planes

Polytope is a C++ library for generating polygonal and polyhedral meshes. It makes use of various 2D and 3D tessellation techniques, but provides a single representation for these tessellations, and a simple interface for generating them. Polytope has a simple C interface for use with other languages. It also includes bindings for Python. These bindings allow you to easily incorporate Polytope into your own mesh generation tools.
