Creating 3D web maps with Cesium
summary
An open‑source JavaScript globe called Cesium renders terrain (SRTM/NED up to ~3m) and imagery with WebGL, uses glTF for optimized 3D models (COLLADA→glTF conversion offline), and encodes time dynamics with CZML. Heavy geometry and triangulation run in web workers, fragment shaders handle imagery tweaks, and the engine streams tiles and terrain live. Production use includes NORAD Santa with 20 million hits (WebGL ~50% success ≈10M users) and a 15,000‑satellite real‑time display; engine is ~80k LOC with extensive tests.
