Rotation animation

Troubleshooting graphics

I want to rotate a cube shaped model by one of its edge. I did the following code.


                Node dice;
      Quaternion x0 = new Quaternion();
      x0.fromAngleAxis(0, new Vector3f(0, 0, 1));
      st.setRotation(0, 0, x0);
 
      Quaternion x180 = new Quaternion();
      x180.fromAngleAxis(FastMath.DEG_TO_RAD * 90, new Vector3f(0, 0, 1));
      st.setRotation(0, 3, x180);
      dice.addController(st);



but all I got is a rotation about axis originated from center of the object.

Anyone know how to make my dice rotate about one of its edge?

Thanks

You might attach the dice to another node and rotate that helper-node's axis.
