This gaming monitor features a 3440x1440 QD-OLED panel with a 175Hz refresh rate and a 0.03ms response time to keep your gameplay smooth. There's also an OLED Care Pro proximity sensor that detects when you walk away and automatically turns the screen black to prevent burn-in. And because the color accuracy is so high (it features true 10-bit color and VESA DisplayHDR 400 True Black compliance), it doubles as a great screen for photo and video editing. They even throw in a free three-month subscription to Adobe Creative Cloud to prove it.
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.
