In SM64, positions are stored as tuples of three floats. However, a programmer at nintendo thought that casting to short ints for collision detection would be fine. (a completely valid idea tbh, after all Mario was never intended to move out of bounds).

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.，详情可参考WPS下载最新地址
