[JAVA3D] Picking (for a change!)

[Tim Uren]

Hi all,   I wonder if any kind soul can help?   I am in the latter stages of developing a simple modelling program and am trying to 'glue' objects together to form more complex models.  So far during the development each new primitive has been added to the same branch group for simplicity, and picking has worked fine returning Shape3Ds, Groups etc.   However, during the glueing procedure I am reparenting the selected object's branch group: detaching it from its current location and then adding it to another object's branch group or transform group.   Picking the newly 'glued' object then fails to work, unless it and its 'owner' object are roughly in line with the view.  Why is this, and what can I do to solve the problem?   Thanks in advance,   Tim
