This project aims to provide a set of libraries for various common graphics programming tasks. These libraries can be used together, to perform the tasks of a typical monolithic 3D engine. Or separately, to cover specific needs of any graphics program.
GLplot is a Mathematics function plotting program based on OpenGL. It can be used to plot functions in 3 dimensions. The results are not as good as Mathematica or Matlab but it gives a good example or OpenGL programming.
