It is not surprising that many researchers – one poll last year by the journal Nature gave the number of 75% – say they are considering leaving the US entirely.
Quadtree-based image compression formats and level-of-detail systems all work this way. Satellite imagery, terrain rendering, and geographic information systems use quadtree decomposition to serve data at varying resolutions: zoomed out, you see large coarse blocks; zoomed in, you see fine-grained tiles. The same principle extends to three dimensions (octrees) for volume rendering and 3D spatial indexing.。业内人士推荐safew官方版本下载作为进阶阅读
