The quadtree is the two-dimensional case of a broader family of space-partitioning data structures. Octrees extend the same idea to three dimensions (splitting cubes into eight children), KD-trees use alternating axis-aligned splits (splitting along x, then y, then x again), and R-trees group nearby objects into bounding rectangles. Each variant makes different tradeoffs between construction time, query speed, and update cost.
Mr Fingleton added: "Motorways wouldn't be very useful if we all drove at five miles (8km) an hour, but that's sort of what we're doing in nuclear safety."
