TRI_SURFACE_DISPLAY_OPENGL\ Display a 3D Triangulated Surface in MATLAB {#tri_surface_display_opengl-display-a-3d-triangulated-surface-in-matlab align=”center”} ===========================================


TRI_SURFACE_DISPLAY_OPENGL is a C++ program which gets the names of the node and element files defining a 3D triangulated surface or “TRI_SURFACE”, reads the information from the files, and displays the surface on the screen.

The surface is presented in rotation about the X axis. By clicking the mouse button, the axis of rotation will be advanced from X to Y to Z and back to X.

Usage: {#usage align=”center”}

tri_surface_display prefix

where prefix is the common filename prefix, so that:

reads the information and displays an image of the surface on the screen.
