Indeed, thats what I meant. As long as auto bounds computation is enabled.

Kevin hi,

Do you mean that the radius of a BoundingSphere implies on the size of the loaded object (geometry) and the center point on the location ?

The bounds of node should tell you this. Although its not always that accurate in my experience.

There are several reasons you may not be able to see your model.  Most
likely is the size.  How big is your model?  Are you inside it?  You say
"I pointed the viewer to that 0.0 after I took it alittle back", but is
your object hundreds or thousands of units big and you only stepped back
a few units?

Another common issue is making a model with no material (thus invisible
- we don't even load it).

hi,

I'm using the "com.mnstarfire.loaders3d.Loader3DS" to load a .3ds
model and I see nothing.
It's there, but I can't see it.

Here is what I did:

1. Create SimpleUniverse.
2. Create SceneGraph with BranchGroup and 2 TransformGroup(scale and
position).
3. Add it to the universe.
4. Create 3DS loader and load the scene
5. Retrieve the BG root
6. Add it to the bottom most TG.
7. Add default lights (2 directional and 1 ambient).

I checked the absolute position of the loaded sub tree and it's 0.0 so
I pointed the viewer to that 0.0 after I took it alittle back.
I set the back and front clip to 100, 0.1 as well. still nothing.

Please if someone can help I'll be very grateful.

Thanks David.
