shear(atTime:)
Returns the x-, y-, and z-axis shear factors of the transform relative to its parent coordinate space, as of the specified time sample.
Declaration
func shear(atTime time: TimeInterval) -> vector_float3Parameters
- time:
The time sample for which to request information.
Return Value
The scale factors of the transform.
Discussion
Together with the translation, rotation, and scale factors, a shear vector defines the local coordinate space for any object affected by the transform, relative to a parent coordinate space. To work with the complete transform, use the localTransform(atTime:) and setLocalTransform(_:forTime:) methods.
Requesting a sample outside the time range clamps results to the minimumTime or maximumTime sample. Some asset formats support continuous sampling with interpolation for times between the samples stored in the asset; others are discrete. For an asset with discrete time information, requesting a sample time in between the samples stored in the asset returns data for the immediately preceding time.
