The mathematics generalizes to 3D quite easily, but the way the webgl pipeline is used in this case doesn't. It'd be easier I think to start from scratch. I recommend reading through the GPU Gem's article on the topic with code samples http://http.developer.nvidia.com/GPUGems3/gpugems3_ch30.html http://http.developer.nvidia.com/GPUGems3/gpugems3_ch30.html although the physics is discussed, you don't need to follow it deeply to implement it
