A voxel cone tracing implementation for real-time global illumination. Voxel cone tracing is used to create effects such as transparency (by refraction), reflections (diffuse and specular) and soft shadows. The implementation traces cones through a 3D texture. The 3D texture represents a directly lit voxelized scene.

This demo requires OpenGL 4.4 to run.

Rafael Sabino has adapted this project to run on Mac OS X. For more information, see: https://github.com/phonowiz/voxel-cone-tracing.
