I have a quadtree dilemma. For objects that intersect more than one top-level node (the four child nodes of the root) should it be placed in the root node? Should I list one node per object and give it the largest node it can fit in, or should I list multiple nodes per object for a tighter fit? I'm considering situations where the object may be small, but it is in the dead center of the world or crossing one of the half-way boundaries of the world.
