Tria, I'm going from memory here, but if I recall, in order to use "USE_GEOMETRY" in pickAllSorted, you need to first iterate throughout all your (Shape3D) nodes in your scene (or the subgraph under PickObject) and set the capability Geometry.ALLOW_INTERSECT. Thus for every node that you know to be a Shape3D do something like: ((Shape3D)myNode).getGeometry().setCapability(Geometry.ALLOW_INTERSECT); Alternatively, you can use PickObject.USE_BOUNDS instead and not worry about this. It provides coarser control but should not matter if your end goal is to get the specific Point3d on an object via PickRay--and you have a sparsely populated universe.. Hope this helps. -guillermo [EMAIL PROTECTED] Tria wrote: > Hi.. > > Supposed that I have a class extended from Shape3D.
