Re: [JAVA3D] Object detection

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();
