WebI have some experience in scientific computing, and have extensively used kd-trees for BSP (binary space partitioning) applications. I have recently become rather more familiar with octrees, a similar data structure for partitioning 3-D Euclidean spaces, but one that works at fixed regular intervals, from what I gather. population and urbanization https://constantlyrunning.com
