Real image compression (JPEG, PNG) uses different techniques (DCT, entropy coding), but quadtrees capture the same principle: spend your bits where the detail is, not uniformly across the whole image.
We wanted a scenario where, say, 5 well-placed border points could efficiently represent an area with 5,000 internal points and 10,000 road edges. This would reduce those 10,000 edges to just 5*4/2 = 10 shortcuts for routing through that cluster at a high level – an incredible 1:1000 point ratio and a 30x reduction in edges to consider for the high-level path!。服务器推荐对此有专业解读
