[JAVA3D] Decal Group

[Sackmunky]

Question: I am placing the texturedSphere and the lines on top in a Decal Group. I have set the capabilites of the texture to DECAL. The only problem is that I can see the back of the globe. Is there anyway that I can tell JAva3D just to show the lines that are visible to the viewer? Thanks Zak   Attached is a picture of the scene.
