smoothrotation
vector smoothrotation(int order, vector r, vector r_reference)
Returns the Euler rotations that have the closest values to r_reference while still describing the same orientation as r. Typically, r_reference will be the rotations from the previous sample or frame.
The angles are in radians. Use the radians() function to convert degrees into radians.
