Hi again,

This last solution worked 100% :)
I have to say thanks to all of you for the help.

It sounds like you set the user data on the Box (a Group), but not on
the Shape3Ds that make up the Box (the faces). You need to recursively
set the user data on all nodes of the Group to ensure that you have it
after a pick.

See the VrmlPickingTest example from my book:

Carlos,

I think you have to cast the node to a Shape3D, as follows:

System.out.println(((Shape3D)node).getUserData());

Hope, it works for you,

Dirk

Subject: [JAVA3D] Another Identify Picked Object Problem :(

Hi all of you, and thanks for your precious help :)

I tried to make the identification by doing this:

       public void mouseClicked(MouseEvent e){
               System.out.println("*** Mouse Click ***");

               pickCanvas.setShapeLocation(e);
               PickResult results = pickCanvas.pickClosest();
               //Node node = results.getObject();

               if (results != null)
               {
                       System.out.println(results);

System.out.println("-----------------------------");

                       //System.out.println(node.getUserData());
               }
       }

This works very well with the commented lines and print the results
variable like this,
where cuboGeloID is the text that i gave to the box with setUserData. So i
think that
the box has an identifier and it was picked sucessfully:

Print of the results variable after picking:

*** Mouse Click ***
PickResult: sgp:[EMAIL PROTECTED] :

: com.sun.j3d.utils.geometry.Box, cuboGeloID :

-----------------------------

But if i uncomment the lines in my code to use the getUserData
i get the null from the getUserData :(

Am i doing anything wrong? Can anyone help.

Thanks again
