"What we can do fairly inexpensively is simulate the physics of a very strong gravity field acting upon a number of particles. By simulating a thousand particles or so, a very pleasing visual display can be created. Using a simple iterative solution, the physics can be calculated quickly, while still resulting in true 'Kepler' orbits, within limits."
"We'll use OpenGL as the 3D API in order to leverage any 3D hardware that might be available on the machine. Some basic understanding of OpenGL is assumed in this article....The accompanying program is similarly structured as well."
