GLgraph is an interactive OpenGL based function
grapher for Linux written in Perl. It visualizes
any mathematical function in 1, 2, or 3 unkowns
(x,z,t) in a 2D, 3D, or 4D wireframe or solid
surface. It creates an animation after one time
period. GLgraph has a command line interface to
input a function, to specify the minimum and
maximum plotting bound, and more. It can be
interactively controlled with the keyboard.
