Instructing the Confusing Fixed-point Rotation

The description of fixed-point rotation needs two three-dimensional coordinates,three independent variables.The relations of this coordinates and variables are so complexity that it's difficult to show the movement of fixed-point rotation.Instructing the fixed-point rotation becomes a problem.Using 3D animated graphics assist teaching;we have solved this problem well.
