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.

I started on a simple path tracing algorithm to learn a little about this method. Path tracing and bi-directional path tracing is the method that by far gives the most realistic looking images. However this is not the case with my implementation yet. Here is one of my first test images. For this image I traced 512 samples per pixel:
