tri_surface_to_obj

tri_surface_to_obj, an Octave code 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:

• a node coordinate array containing the coordinates of nodes;
• a triangle node array containing triples of the indices of the nodes used to form each triangle;

An OBJ file is format for storing a description of the surface of a 3D object, composed of triangles or higher degree polygons.

Usage:

tri_surface_to_obj ( 'node_file', 'element_file', 'obj_file' )

• 'node_file' lists the coordinates of nodes;
• 'element_file' lists the indices of nodes forming elements;
• 'obj_file' is the name of the OBJ file to be created.
