Yeah, that is a very long answer to the original question of pixels vs voxels. A pixel is a picture element (2d) and a voxel is a volume element (3d). Also, it's not necessary to take the displayed path, i.e., triangulate a voxel-based representation then use vector-oriented rendering methods to get the displayed image. There have been lots of work rendering a 2d display by ray tracing through voxel space or even directly splatting voxels into display space. A lot of research has been directed into efficient representations for large collections of voxels. One really cool sparse volume system, OpenVDB, was open sourced by DreamWorks: http://www.openvdb.org/ http://www.openvdb.org/. Nvidia has papers on sparse voxel octrees that work very well on GPUs: https://research.nvidia.com/publication/efficient-sparse-voxel-octrees https://research.nvidia.com/publication/efficient-sparse-vox...
