Hello everybody!
I have a problem to establish exact picking of shapes.
If I set a picking mode to GEOMETRY, the exactness is exelent,
but Shapes that have LineStripArray geometry in them can not be
picked at all.
If otherwise I set a picking mode to BOUNDS, every type of geometries can
be picked, but now the exactness of picking is terrible, since Java3D
uses BoundingSphere to compute object bounds.
Here is an example of my picking function:
public void updateScene(int xpos, int ypos) {
Shape3D shape = null;
pickCanvas.setShapeLocation(xpos,ypos);
PickResult pr = pickCanvas.pickClosest();
if(pr != null)
shape = (Shape3D) pr.getNode(PickResult.SHAPE3D);
univ.UpdateCurrent(shape); // My function that does something with
// picked shape
}
Does anybody knows the solution to this problem?
Boris.
