We are aware of this problem and plan to address it in 1.2. In the
mean time, your solution should work, if you know what transforms above
you can change.

>Hi fellow j3D addicts,
>Following a related issue discussed a couple of days ago, I am overloading
>the Billboard behaviour to only wakeup on a change of viewing platform
>transform.
>The purpose is to avoid continuous rendering which is taking all my CPU
>To achieve this, I use the following class
>
>public class MyBillboard extends Billboard
>{
> TransformGroup pt = null;
> WakeupOnTransformChange wakeupFrameTG;
> public MyBillboard(TransformGroup transformgroup, int i, Point3f
>point3f, TransformGroup platformTransform)
> {
> super( transformgroup, i, point3f);
> pt = platformTransform;
> wakeupFrameTG = new WakeupOnTransformChange(pt);
> }
>
>
> protected void wakeupOn(WakeupCondition p0) {
> super.wakeupOn(wakeupFrameTG);
> }
>
>}
>
>This seems to work my billboard is triggered after each transform change,
>sadly the result is not displayed:
>indeed the rendering loop seems to ignore the change and do not force a new
>render
>Is this the reason behing the continuous rendering set in Billboard?
>Is this a bug?
>Can we manually trigger a new render ?
>Hope I have not confused you
>Thanks in advance
