Sparse Voxel Octree (SVO) Raycasting the Stanford Dragon
The octree is about 400MB, created from a 4k x 2k x 2k volume (32 bit color). The video was captured on a GTX260 graphics card where the frame-rate has been around 40 to 70 at a resolution of 1024x624 (for HD). The algorithm uses SVO raycasting and is implemented in CUDA.
