PLY_TO_TRI_SURFACE is a MATLAB program which reads data from a PLY file describing a polygonal mesh of a 3D surface,and converts it to a pair of arrays describing a triangular mesh or TRI_SURFACE.
A PLY file contains a sophisticated data structure describing a polygonal surface. 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_SURFACE or triangulated mesh surface, is described by a pair of arrays:
[ node_xyz, triangle_node] = ply_to_tri_surface ( 'ply_file_name' )where
