EPIC games just released two impressive videos presenting their new UE4 game engine featuring real-time global illumination that supports diffuse and specular bounces on dynamic scenes.

According to this interview of Tim Sweeney, their technique is called SVOGI (Sparse Voxel Octree Global Illumination) and... it is based on the voxel cone-tracing technique we published last year at Pacific Graphics ! :-D

That's really awesome to see research results being used so quickly in a game engine ! Beyond the paper, you can find more details about our voxel cone-tracing approach in my GTC 2012 talk, my Siggraph talk, as well as in my Ph.D thesis on GigaVoxels.
