Point Cloud Level of Detail in Python: Octrees, Frustum Culling, and Out-of-Core Rendering

A cloud bigger than your memory still spins at sixty frames a second. The trick is the one your maps app already plays on you: a pyramid of pre-cut tiles, called an octree, that loads detail only where you are looking. Here is the full machinery, with a runnable Python demo.
