Hi,
take a look at the demos:
- demo/java3d/PickTest
- demo/java3d/PickTest3D
- demo/java3d/TickTockPicking
the last is the biggest.
Basic idea:
*************************************************
import com.sun.j3d.utils.behaviors.picking.*;
...
createSceneGraph
...
objTrans.setCapability(TransformGroup.ENABLE_PICK_REPORTING);
...
Shape3D shape;
shape = (Shape3D) pickScene.pickNode(pickScene.pickClosest(xpos, ypos,
PickObject.USE_BOUNDS),
PickObject.SHAPE3D);
***************************************************
Hope that helps,
J�rg
