If an asset contains timed information, such as animated mesh data, this property provides the asset’s bounding box as of the first time sample. Use the
boundingBoxAtTime: method to get bounding box information at a specific time sample.
All assets can provide bounding box information without traversing their hierarchy of objects.
Working with Asset Content
Returns the top-level object at the specified index in the asset.
The number of top-level objects in the asset.
Adds the specified object to the asset’s list of top-level objects.
Removes the specified object from the asset’s list of top-level objects.
Returns the minimum region entirely enclosing the asset’s contents at the specified time sample.
The URL from which the asset was loaded, if available.
An object responsible for allocating mesh vertex data loaded from the asset.
The description of the vertex data format to be used for loading mesh data from the asset.
An array of objects that can be reused in the asset's object hierarchy through instancing.
