polygonal_surface_display_opengl

polygonal_surface_display_opengl, a C++ code 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

• prefix_nodes.txt contains the node coordinates;
• prefix_elements.txt contains indices of nodes that form the elements;
