Just a slight addition. It might be nicer (and more efficent) if you store a specifically designed data object in the user data. Then you'd have all your data readily available and typed as soon as you got your picked node, instead of parsing the string. > Hope this helps. > > C YA Phil :) > > > >>===== Original Message From Discussion list for Java 3D API > <[EMAIL PROTECTED]> ===== >>Hi, >> >>I've been using the PickCanvas for some time now to pick 3D points in >> my > scene.
