Sparse Voxel Octrees

I'm looking for all materials, books that will allow me to build simplest voxel rendering engine oparating on sparse voxel octrees. I will probabbly be using python or more likely javascript so lots of things have to be开发者_开发问答 written from scratch as webGL/openGL doesn't support voxels. Thanks in advance.

Space-filling-curves: z-curve, hilbert curve, moore curve, quadkey, spatial index.

this is one I referred to before when I had an interest in voxels:

You'll have to convert the source yourself, but at should at least introduce you to the basic concepts.

For a specific reference on SVO, there was a whitepaper released by NVidia, but it's a bit heavy on the math: http://www.tml.tkk.fi/~samuli/publications/laine2010tr1_paper.pdf
