Detailed Description

Space-partitioning acceleration structure for points. Partitions the points into voxels to accelerate range and nearest neighbor searches.

Note

Leaf nodes store a single point-index array and the voxels are only integer offsets into that array. The actual points are never stored in the acceleration structure, only offsets into an external array.
