Cesium3DTileset

readonly boundingSphere : BoundingSphere
Get the bounding sphere derived from the tile's bounding volume.
readonly children : Array.<Cesium3DTile>
Gets the tile's children.
readonly computedTransform : Matrix4
The final computed transform of this tile.
readonly content : Cesium3DTileContent
The tile's content. This represents the actual tile's payload,
not the content's metadata in the tileset JSON file.
expireDate : JulianDate
The date when the content expires and new content is requested.
The time in seconds after the tile's content is ready when the content expires and new content is requested.
Returns the
extras
property in the tileset JSON for this tile, which contains application specific metadata.
Returns undefined

The error, in meters, introduced if this tile is rendered and its children are not.
This is used to compute screen space error, i.e., the error measured in pixels.
Gets the I3S Node for the tile.
readonly parent : Cesium3DTile
This tile's parent or
undefined
if this tile is the root.
When a tile's content points to an external tileset JSON file, the external tileset's
root tile's parent is not undefined
; instead, the parent references
the tile (with its content pointing to an external tileset JSON file) as if the two tilesets were merged.
readonly tileset : Cesium3DTileset
The tileset containing this tile.
transform : Matrix4
The local transform of this tile.
