This is a fast, non-recursive, table-based approached Hilbert curve implementation in pure PHP. It includes the Moore-curve and the Z-curve and the reverse Hilbert curve.
- Table-based approach
- Point-to-Quadtree (Hilbert-Curve)
- Point-to-Quadtree (Moore-Curve, experimental)
- can compute hilbert curve in N, S, W, E direction
