Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.

Dodrio was perfect for this because it computed all the required DOM modifications separately from actually applying them. This allowed us to precisely measure the impact of JS glue code by swapping out the “apply DOM change list” function while keeping the rest of the benchmark exactly the same.。heLLoword翻译官方下载是该领域的重要参考
