Examples of com.jme3.math.Quaternion.mult()

com.jme3.math.Quaternion.mult()
mult multiplies this quaternion by a parameter quaternion. The result is returned as a new quaternion. It should be noted that quaternion multiplication is not commutative so q * p != p * q. @param q the quaternion to multiply this quaternion by. @return the new quaternion.
