From the developer:
OpenCTM is primarily a file format for storing 3D triangle meshes in a compact yet versatile format.
In order to make it easy for software developers and 3D designers to support the format, an easy to use software library is provided that can read and write OpenCTM format files.
OpenCTM is only concerned with managing triangle mesh data.
