Syntax
struct FZOrderCurvePoints
Remarks
Generate a "z-order curve" ordering for a point set by distributing the points to a quad- or octree and then reading the points indices back in tree traversal order This is useful for giving the points spatial locality so points that are close together in the ordering tend to be close together spatially, also
