Performs Normalized Linear Interpolation (Nlerp) between two quaternions, start and end, using the interpolation factor t. This method is suitable for efficiently interpolating 3D rotations.
Performs Spherical Linear Interpolation (Slerp) between two quaternions, start and end, by an interpolant t. Slerp provides smooth interpolation of rotations with constant angular velocity along the shortest path on the 4D unit sphere.
Performs Spherical Linear Interpolation (Slerp) between two quaternions, start and end, by an interpolant t, ensuring that the interpolation takes the long path if a shorter rotational path exists.
