opengl_test a C code which uses OpenGL to display graphics information.
OpenGL is most commonly used with C or C++ codes, but can also be called by a Fortran program if the necessary intermediate "Fortran bindings" (an interface package) have been installed.
OpenGL only does graphics rendering, and has no concept of windowing systems, input devices, printing to the screen and so on. These extra functions must be provided by an auxilliary package. One common package as known as GLUT, for the Graphics Language Utility Toolbox.
