Suppose the black box represents the screen boundaries and the red boxes represent quad tree leaf boundaries:
Currently client browsers will download object files corresponding to all of the red boxes. However, this likely results in downloading information about the same edges and nodes more times than necessary.
Instead, we can store object files corresponding to internal nodes of the quad tree as well. Then clients can download object files corresponding to the green boxes instead of the red boxes, reducing the amount of duplicate information downloaded.
