For those who do not need continuous updating while using billboards:
Following Doug's explanations (Thanks again), I now use the following trick:
public class MyBillboard extends Billboard
{
/* the viewplatform transform group */
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 way, my billboards are only activated when the viewer change
position...
This seems to work correctly.
Hope it helps
