3D Tiles
From Just Solve the File Format Problem
3D Tiles is a JSON-based format designed for streaming and rendering geospatial data consisting of 3D objects organized in a hierarchical structure involving tilesets. The tiles may be of different sizes and are organized in a tree structure rather than a fixed grid. A right-handed Cartesian coordinate system is used to locate the objects.
Various formats of data can be embedded as binary blobs. The glTF format is used as the basis of object models.
