The company’s tech comes from an unusual source: a $100-million-endowed program at Caltech to develop orbital solar plants that would beam electricity to Earth below. The researchers ultimately settled on a sail-like structure that is thin and flexible compared to boxy, traditional satellites.
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91视频
