obj_to_tri_surface, an Octave code which reads data from an OBJ file describing a polygonal mesh of a 3D surface, and converts it to a pair of arrays describing a triangular mesh or TRI_SURFACE.
Since the faces in an OBJ file can be of any polygonal order, while the faces in a TRI_SURFACE file must be triangular, the program automatically uses a crude method to break up higher order faces from the OBJ file into triangles.
An OBJ file is format for storing a description of the surface of a 3D object, composed of triangles or higher degree polygons.
A TRI_SURFACE or triangulated mesh surface, is described by a pair of arrays:

obj_to_tri_surface is available in a MATLAB version and an Octave version.
obj, a data directory which contains a description and examples of OBJ files.
