TET_MESH_DISPLAY_OPENGL
Display a Tet Mesh Using OpenGL


TET_MESH_DISPLAY_OPENGL, a C++ code which reads the name of two data files defining a tetrahedral mesh ("tet mesh"), reads the data, and displays the tet mesh using OPENGL.

The files defining the tet mesh consist of one file containing the coordinates of the points, and a second file that lists the indices of the nodes making up each tetrahedron. Either 4-node or 10-node tetrahedrons may be used.

Usage:

tet_mesh_display_opengl prefix
where prefix is the common file prefix:
