There are few things sadder than the end of a close friendship. Whether it happens in a sudden moment of betrayal or after years of gradual separation, the feelings of loss can stay with you for a lifetime.
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.
