[JAVA3D] how to wake up?

[Chauveau Wong]

Hi,

 Can anybody help with my problem? Thanks a lot.

 I draw an arrow pointing from one box to another. When the box moves or
zooms, I can detect it by using WakeupOnTransformChange(). But how to wake
up when the boxes rotate?


       ArrowEvents = new WakeupCriterion[2];
       ArrowEvents[0] = new WakeupOnTransformChange(tg1);
      // tg1 is the transform group of one box
       ArrowEvents[1] = new WakeupOnTransformChange(tg2);
     // tg2 is the transform group of another box
       ArrowCriterion = new WakeupOr(ArrowEvents);
