The time sample for which to request information.
The scale factors of the transform.
Together with the translation, rotation, and shear factors, a scale factor 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
Requesting a sample outside the time range clamps results to the
maximum 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.
