TRI_SURFACE_IO is available in a C++ version and a FORTRAN90 version and a MATLAB version.
PLY_TO_TRI_SURFACE, a MATLAB program which extracts data from a PLY file and writes it to a TRI_SURFACE file.
TET_MESH_BOUNDARY, a FORTRAN90 code which returns the nodes and faces of the boundary of a tetrahedral mesh, which themselves form a 3D triangular mesh or "TRI_SURFACE".
