Hi Andreas,
thanks for your suggestions.
We found out that the pickray was picking backwards (for some strange
reasons)! So now we we get the direction of the pickConeRay and then we set
this direction negative.
We also found an other strange thing :
If you specify a shapeRay and after that you set the shapelocation, then the
pickshape is changed to a ConeRay!!!???
pc = new PickCanvas(canvas3D, topBranchGroup);
pc.setMode(PickTool.BOUNDS);
pc.setTolerance(4.0f);
pc.setShapeRay();
pc.setShapeLocation(mouseEvent);
//Here the pickshape is changed to a coneray!!!!
pickResult = pc.pickClosest();
if (pickResult != null) {
System.out.println(pickResult.toString());
}
But now all is working fine.
gr. Bart

I assume you aren't getting any intersection information when you pick,
that's
why PickCanvas always returns the same object on not the closest (because
intersection information is used to calculate the distance). Try setting the
tolerance of PickCanvas to zero :-) That should
a) work
b) be documented in the API!

Andreas
