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.

First screenshot from my new SAH KD-tree. The bunny is visualized using the voxels only.

To better visualize the voxels traversal I implemented an interactive tool that allows me to trace a single ray while showing only the inspected voxels in that trace. This tool is very valuable debugging the KD-tree.
