Cesium ion is an online platform for tiling, optimizing, and hosting 3D data. Built on modern cloud architecture, the application can efficiently stream large datasets into web applications like CesiumJS that can be shared with others across any device.

Upload your massive worlds, scenes and models from Autodesk® 3ds Max® to Cesium ion, and ion will optimize it, tile it into 3D Tiles, and stream them to any device in Cesium's 3D geospatial world along with other contextual data such as terrain and satellite imagery.
