boundingBox(atTime:)
Returns the minimum region entirely enclosing the asset’s contents at the specified time sample.
Declaration
func boundingBox(atTime time: TimeInterval) -> MDLAxisAlignedBoundingBoxParameters
- time:
A timestamp referring to timed information in the asset.
Return Value
The asset’s bounding box as of the specified time sample.
Discussion
If an asset does not contain timed information, calling this method with any time sample is equivalent to reading the boundingBox property.
All assets can provide bounding box information without traversing their hierarchy of objects.
