Day Eight: QuadTree Interlude Pt. 4
Find who is in the same qTree box as me, find points in a circle. In the first one there is an interesting artifact where the grid laid out by fetching all the subtrees is not the same exactly as the overlay of the found subtree, depending on ones zoom level.
The third sketch uses perlin noise instead of guassian random to create the point cloud.
Hover the mouse over the sketch to make it run.
