SVO Voxel Raycaster Tech Demo with Image Warping

Postby spacerat » Thu May 21, 2015 3:03 pm

I decided to release a tech demo of the sparse voxel octree raytracing re-projection algorithm. Feel free to download and try it out. It uses OpenCL and should run on NVIDIA in any case. For ATI and INTEL HD I cannot guarantee.

Usage:
Mouse : Look around
w,s,a,d,q,e : Move around
Space : See the re-projected pixels

The algorithm raycasts only a fraction of pixels for each screen. Most are re-used from the previous frame exploiting frame-to-frame coherency, which allows a speed up of up to 4x. The algorithm is explained here: http://voxels.blogspot.com/2014/05/raycaster-speed-up-up-to-400-by-image.html.

You can download the Demo here: http://www.outstar.net/files/SVO-Reprojection-TechDemo.zip
