Octray Shaders is an experimental Ray Traced shaderpack for Minecraft. Octray implements an Octree-like acceleration structure for its raytracing. This allows rays to be cast long distances in sparse environments with significantly fewer intersection-checks. Octray also contains a few other inventions, such as a pseudo-recursive branching GLSL raytracer, implemented using a ray stack. The most significant feature was de-noising.
