ply_io


ply_io, an Octave code which reads or writes data describing a 3D polygonal mesh in a PLY file.

A PLY file contains a sophisticated data structure describing a polygonal surface in 3D. A triangulated mesh is a very simply case of such a surface; a PLY file can also describe a mesh surface involving higher order polygons, and it can contain auxilliary information about normal vectors and so on.

A TRI_MESH or triangulated mesh surface, is described by a pair of arrays:
