   RotateVelocity based on y axis or x axis doesn't work. only work if use z axis.

   In Flint, the particles are treated as billboards - they always face the camera. This is a simplification for performance purposes. I'm debating whether to change this in a future version. The upshot is that to see the rotation in the Y axis you need to move the camera to a position that is not perpendicular to that axis.
   
   e.g.
   renderer.camera.position = new Point3D( 0, 200, -300 );
renderer.camera.target = new Point3D( 0, 0, 0 );
   
   Meanwhile, if you need full 3D perspective, you should use the Away3D renderer and use full 3D objects. (N.B. If you use Away3D sprites you again won't see the rotation.)
