Tileset.json's top-level objects have four attributes: asset, properties, geometric Error,
And root.
Asset is an object that contains global tileset metadata attributes. The version attribute is a string that defines the version of 3D Tiles. Version number defines the basic settings of tileset.json's JSON format and tile format. The tilesetVersion attribute is an optional string that defines the version of tileset in a particular application and can be used to update tileset.
Properties is an object that contains information about each attribute of each element in tileset. This tileset.json code snippet is for three-dimensional architecture. Each tile has a building model, and each model has a Height attribute (refer to the Batch Table in the Batched 3D Model tile format).
Each object's name is the same as the corresponding attribute's name in each element, and their minimum and maximum values are defined, which are useful in customizing color order styles.
Geometric Error is a non-negative value that defines metric errors when tileset is not rendered.
Root is used to define root tiles (see the previous section). The root. geometric Error is different from the geometric Error of the highest level tileset.json. Errors defined by geometric Error of tileset.json are used when the entire tileset has not been rendered; errors defined by root. geometric Error are used when only root tiles are rendered.
root.children is an array that defines child tile objects. Each child tile has a bounding Volume, which is completely surrounded by the bounding Volume of the parent tile. Usually the geometric Error of the child tile is smaller than that of the parent tile. For leaf tiles, the length of the tiles array is 0.
So children can also be undefined.
