ratio specifies the point between quaternion 1 and quaternion 2 at which to interpolate. ratio is a number between 0 and 1, inclusive. If ratio is 0, LabVIEW returns quaternion 1. If ratio is 1, LabVIEW returns quaternion 2.

quaternion 1 is a four-element array whose elements specify the scalar and three-element vector parts of a quaternion.

quaternion 2 is a four-element array whose elements specify the scalar and three-element vector parts of a quaternion.

interpolated quaternion returns the interpolated value at the ratio you specify between quaternion 1 and quaternion 2.
