Instance Property

minimumTime

The timestamp for the first timed data sample in the transform component.

Required.

Declaration

@property(nonatomic, readonly) NSTimeInterval minimumTime;

Discussion

Timed data is clamped to the minimum and maximum times. If you request transform data for a time sample before the minimum time, Model I/O returns the transform at the minimum time.

If the transform component does not contain timed information, this property’s value is zero.
