title: 3D Tiles

content: The open specification for 3D data. 3D Tiles is the open standard for massive, heterogeneous 3D geospatial datasets such as point clouds, buildings, photogrammetry, and vector data. Built on glTF and other 3D data types, 3D Tiles is a streamable, optimized format designed to tap the potential of today’s ever-growing collection of 3D geospatial data. Features: Interactive, styleable, adaptable, and flexible; Designed for precision to support the most demanding analytics; Time-dynamic for visualizations or simulations that allow users to see change over time; Heterogeneous, supporting a variety of data types meant for different purposes; there is no one-size-fits-all for 3D datasets; 3D Tiles is an Open Geospatial Consortium (OGC) Community Standard. Building the 3D geospatial ecosystem through openness. Cesium first introduced 3D Tiles in 2015 and shepherded its acceptance as an OGC Community Standard in 2019. 3D Tiles has been widely adopted by leading software, service, and data providers across industry and government, and by developers building end-user applications. The success and impact of 3D Tiles as an open standard reinforces our belief that openness and interoperability are the essential elements that propel not only Cesium, but the entire 3D geospatial ecosystem, forward.
