![A 3D Tiles city styled so that buildings in different tiles are shown in different colors and so each tile's bounding volume is outlined as a box.](https://images.prismic.io/cesium/551156d3-18c8-406a-ad1c-cc3c64c4c58d_bounding-volumes.jpg?auto=compress%2Cformat&fit=crop&crop=faces%2Ccenter&w=660)
3D Tiles styling used to color tiles of buildings and to show bounding volumes
Tilesets and Tiles
3D Tiles provides a way to describe tilesets and their tiles, formatted as JSON.
Along with its properties, a tileset contains a set of tiles arranged in a tree – a spatial hierarchy. 3D Tiles supports a variety of 3D (and 2D) spatial subdivisions to facilitate optimized rendering by visualization software.
A tile:
- Includes or points to the tile’s content.
- May contain child tiles and can refer to external tilesets, making it possible to combine smaller tilesets into larger ones.
- Defines a spatial bounding volume that encloses its children.
