How to get the size of a bounding box or bounding sphere after updating?

I am basically trying to get the size of the bounding volumn(box or sphere) after updating my model's bound, but it keeps giving me 0's for everything; like radius, center x and y etc.



Can anyone please looks at my code and see what's wrong?



Note: I have inserted a system.out.println() in the code right after I updated all the bounds, and the output is:

"com.jme.scene.BoundingSphere [Radius: 0.0 Center: com.jme.math.Vector3f [X=0.0, Y=0.0, Z=0.0]]"



protected void simpleInitGame() {

        // Point to a URL of my model

        URL model = HelloModelLoading.class.getClassLoader().getResource("Spaseship.3ds");



        // Create something to convert .obj format to .jme

        FormatConverter converter = new MaxToJme();

        // Point the converter to where it will find the .mtl file from

        converter.setProperty("mtllib", model);



        // This byte array will hold my .jme file

        ByteArrayOutputStream BO = new ByteArrayOutputStream();

        try {



            // Use the format converter to convert .obj to .jme

            converter.convert(model.openStream(), BO);

            Node maggie = (Node) BinaryImporter.getInstance().load(new ByteArrayInputStream(BO.toByteArray()));



            // shrink this baby down some

            maggie.setLocalScale(10f);

            BoundingSphere bs = new BoundingSphere();

            maggie.setModelBound(bs);

            maggie.updateModelBound();

            maggie.updateWorldBound();

            System.out.println(bs.toString());



            // Put her on the scene graph

            rootNode.attachChild(maggie);

        } catch (IOException e) {  // Just in case anything happens



            System.out.println("Damn exceptions!" + e);

            e.printStackTrace();

            System.exit(0);

        }

    }

getWorldBound()  seems to be working for me.



Hellmaster.

model bounding volumes are set at the leaf level, so that convenience method you are calling at the Node level is setting a new BoundingSphere at the leafs under that Node.  Your original boundingsphere object is not modified.

To Hellmaster: which object did you use to getWorldBound() in my case? maggie??



To Renanse: so, is there a method that I can access the leaf node instead of the unchanged, original one?

Thanks for you guys' replies, I found out the solution in a old thread:
