slerp
fun slerp(a: Quaternion, b: Quaternion, t: Float, valueEps: Float = 1.0E-10f): Quaternion
Content copied to clipboard
Spherical linear interpolation between two given orientations
If t is 0 this returns a. As t approaches 1 slerp may approach either b or -b (whichever is closest to a) If t is above 1 or below 0 the result will be extrapolated.
Return
Interpolated value between the two floats
Parameters
a
The beginning value
b
The ending value
t
The ratio between the two floats
value
Prevent blowing up when slerping between two quaternions that are very near each other. Linear interpolation (lerp) is returned in this case.
