Motor3D::Unitize

Unitizes the weight of a motor.

Motor3D& Unitize(void);

The Unitize function multiplies a motor by the inverse magnitude of its weight, which is the quaternion given by its e₄₁, e₄₂, e₄₃, and antiscalar coordinates. After calling this function, the rotor component of the motor is unit-length. If these coordinates are all zero, then the result is undefined.

The return value is a reference to the motor object.
