-Overview
-SimpleBalancedOctree is a Python package that adaptively partitions point distributions in 2D and 3D into a 2:1 balanced tree structure. The package ensures that any two neighboring leaf nodes are either on the same level or differ by one level, resulting in a neighbor list of bounded size.
