POLYGONAL_SURFACE_DISPLAY_OPENGL is 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.
