Martin,
are you trying to pick to full object loaded,
or a named piece inside the scene loaded ?

Try BranchGroup instead Node
========= PICKING
===================
BranchGroup shapeClicked =
null;
// Get Object Data to determine
part
shapeClicked =
(BranchGroup)
pickResultArray[i].getObject();
Object
shapeSelected = shapeClicked.getUserData();

Subject: [JAVA3D] Object
detection
Hi,
I am wondering if anyone can
help me. I have loaded a vrml file into my
Java3D scene, assign a
setUserData method to the branchgroup with a
relative
name. I have a
separate pick routine that i would like to detect what
object
i have
selected by using the getUserData method.
The problem is that i am
assigning a name to a branch group and when i
do
the pick i am returned
a shape object. I want these objects to be the
same
but i can't find an
instruction which will either assign a getUserData
command to shape3D from
the vrml loaded file or a pick behaviour which
returns the branchgroup
clicked.
file://=========LOADER & ASSIGN
=============
// Call VRML Loader with 'TopfileA.wrl'
Scene scene
= loadVrmlShape(slocation+fileName);
shapeBG =
scene.getSceneGroup(); // get scene branch
group
shapeBG.setUserData("StartObj");
file://========= PICKING
===================
Node shapeClicked = null;
//
Get Object Data to determine part
shapeClicked = (Node)
pickResultArray[i].getObject();
Object
shapeSelected = shapeClicked.getUserData();
