About Gray

Gray (Greiners Raytracer) is a hobby/research project of mine. It is a program that simulates light to produce computer generated images. The technique used is called ray tracing, where a large number of rays are cast against mathematical 3D models to simulate the interaction between light and materials. The result is beautiful computer generated images, like the ones we are used to see in special effects in movies.

Moving my old hand generated html homepage into the blog format. Hopefully with this format I will post news about my progress with Gray much more often than I did with the old homepage.
