Hi,
You don't have to use Shape3D to define primitives such as a cube or a
sphere.
Use the predefined primitives by Java3D, which I think is under the
"com.sun.j3d.....geometry". Check out the index.html of Java3D API to find the
exact location. Then add this primitive (say sphere or block) directly
to your TransformGroup as a child. Don't try to cast it to the
"Shape3D" type..
And add as many as you want. It should work fine. You need extra
TransformGroups
only if you desire different transformations for a specific part (sphere).
By the way, you CAN directly add the spheres to your BranchGroup
if you want your parts exactly on the origin.
