I acquired Pbrt in order to learn the basics of computer graphics rendering in a practical way. However, I struggle even with the most basic things (math mostly).

Do you happen to know of any resource that provides a good mathematical foundation directed at computer graphics?


Any resources you'd recommend for learning about 3D volumetric rendering via voxels (not polygons)?


NVIDIA has some good papers on Sparse Voxel Oct-trees (GPU backed of course). Typically voxel rendering is done via raytracing.


Thanks!

Do you have any opinion of voxel cone tracing vs raytracing?
