voxels

问题 I'm trying to plot cuboids of different sizes using matplotlib, such that: after rotation the cuboids do not overlap visually in a non-physical way, the cubes have different colors and a box drawn around them. I've read several blog posts and stackoverflow pages referencing similar problems, but always with a slight difference; none which have worked for me. The easiest way to overcome the overlapping problem was to use voxels (as in https://matplotlib.org/api/_as_gen/mpl_toolkits.mplot3d

问题 I have reading a lot about the potential use of sparse voxel octrees in future graphics engines. However I have been unable to find technical information on them. I understand what a voxel is, however I dont know what sparse voxel octrees are or how are they any more efficient than the polygonal techniques in use now. Could somebody explain or point me to an explanation for this? 回答1: A NVIDIA whitepaper named Efficient Sparse Voxel Octrees – Analysis, Extensions, and Implementation describes
