POLYGONAL_SURFACE_DISPLAY_OPENGL
Display a Polygonal Surface using OpenGL


POLYGONAL_SURFACE_DISPLAY_OPENGL, a C++ program which gets the names of the node and element files defining a polygonal surface, reads the information from the files, and displays the surface on the screen using OpenGL.

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:

polygonal_surface_display prefix
where prefix is the common filename prefix, so that: reads the information and displays an image of the polygonal surface on the screen.
