The pruned nodes (in red) represent entire regions of space that the algorithm never examines. The points inside those regions are never checked. Compare the "Nodes Visited" count to the total number of points. The quadtree is doing far less work than a brute-force scan.
Babies are beautiful. I always want to smile at them in the street, perhaps because they are a rarer and more precious sight in this ageing country or because they remind me of my grandchildren. There are about 3.5 million children aged four and under, while dogs on the streets are a more plentiful 13.5 million. Is the dog boom compensating for fewer children?
