trimesh is a library and a set of utilities for reading, writing, and manipulating 3D triangle meshes stored as .ply files. Compared to the canonical PLY tools, trimesh reads and writes only a small subset of the possible variants of .ply files, but aims to be more efficient and user-friendly.

A newer (though, unfortunately, not quite compatible) version of trimesh is available from the trimesh2 page.

trimesh includes a C++ class representing a triangle mesh and various utility functions. It is known to compile under IRIX, Linux, and Win32 (only tested with the GNU toolchain), and should be relatively portable to other systems. It is distributed free for non-commercial educational and research use.
