#interactive #quadtree (move your mouse)

u/tomxor

Note the intersection is fuzzy since full circle-AABB takes too much code, instead it's just circle-point + current subdivision width based radius (w*w*6.28), i.e it becomes more accurate as it converges.
u/tomxor

This is why there are a bunch of divisions around it that would not exist with an exact test. Pavel's doesn't do this by cleverly choosing a geometry that only need intersect the top left of each square.
u/katkip

Nice!

The cursor if off in the y direction. I wanted to change the 3 multiplier to 3.4 but couldn't figure out where to save characters. Any suggestions would be much appreciated!
