This week I gave a talk at the NVIDIA GPU Technology Conference about a fast sparse voxelization technique that I worked on at NVIDIA in the context of my real-time global illumination approach (using voxel cone-tracing inside a sparse voxel octree).

In this talk I first give an overview of the real-time GI approach, before quickly detailing the new GPU voxelization and octree construction algorithm.
This sparse voxelization technique will be published in the OpenGL Insights book that will be out for Siggraph.
[UPDADE 07/12] The book chapter in OpenGL Insights has been published online here.
