luigi,
The example HelloJava3dc.java provides a simple
illustration on how to use rotation interpolator.
It shows that you need to use an alpha class
generating a time varying function and rotatioon interpolator
As a starting try to execute it and adapt it to your application.
for example to rotate the object at 15 degrees/second just one time
you may need to set the parameters of the alpha function (generating the
time varying function) at 1 and 360x1000/15.
Hope this helps
