|Quat a||Start quaternion, should be normalized/unit length.|
|Quat b||End quaternion, should be normalized/unit length.|
|float slerp||The interpolation amount! This’ll be a if 0, and b if 1. Unclamped.|
|RETURNS: Quat||A blend between the two quaternions!|
Spherical Linear intERPolation. Interpolates between two quaternions! Both Quats should be normalized/unit quaternions, or you may get unexpected results.
