TRI_SURFACE_TO_OBJ is a MATLAB program which reads data from a TRI_SURFACE file describing a triangular mesh of a 3D surface, and converts it to an OBJ file.
A TRI_SURFACE or triangulated mesh surface, is described by a pair of arrays:
An OBJ file is format for storing a description of the surface of a 3D object, composed of triangles or higher degree polygons.
