There is a lot of energy right now around sandboxing untrusted code.

The answer was the US Navy, which was hungry for new pilots after World War Two. It was not building rockets but at least it involved flying.

The algorithm maintains a running "best distance" that starts at infinity. As it walks the tree, it checks each visited point and updates the best distance if it finds something closer. Before recursing into a child node, it checks whether the closest possible point in that child's bounding box is farther than the current best. If so, the entire subtree gets pruned.
