wonder how much crap is required to get basic voxel sculpting up inefficient version is just big ole array or bit bank (more efficient version involves octrees, "bricks", roaring bitmaps and the like) marching tets or cubes to get a mesh, then shovel that down to the GPU (i found a paper that does some subgrid marching tets, which gives smoother meshes without all the banding) some projection math to find where the brushes go hmmh
