We choosed a fully other way because we are Vega users. To pick something we
used a line-of-sight-Isector. The origin was copied from observer. The
direction is set using the coordinates of mouse pointer transformed into real
world coords. We - my girlfriend and me - needed from Sunday evening until
Monday morning to implement this. It works nice. (Our greatest problem was to
change our motion model to free the left button for picking. ;-)) If you can't
solve your problem not at all you could think about such or similar solution
like our.
I guess pfPick is a similar solution for convinience, isn't it?
Best regards,
Dirk.
