A guide to fast voxel ray tracing using sparse 64-trees
Introduction If you have ever tried to ray trace voxels before, you might have heard about Sparse Voxel Octrees. They are one of those ideas that are just simple and clever enough to be intriguing, but not so great to hold in practice at the basic premise. That is to say, I was not very impressed to find from some benchmarks that even one of the state of the art ray-traversal implementations…
