Help Us Shape Composable Tiling Pipelines for Next-Gen Workflows
Written by 
Jake Adelgren,
3D Tiles has become the foundational OGC community standard for the 3D geospatial ecosystem. Massive, heterogeneous 3D geospatial datasets such as 3D photogrammetry and reality models, 3D buildings, point clouds, and Gaussian splats can be encoded as 3D Tiles, optimized for streaming, and rendered with high precision and performance. To power these experiences, Cesium has built robust tiling pipelines to process various types of source data into highly optimized tilesets. Because 3D Tiles is built for interoperability, these tilesets can be seamlessly streamed and visualized across a wide-open ecosystem of runtime engines, including CesiumJS, Cesium for Unreal, Three.js, BabylonJS, QGIS, and Godot.
