Yes, each object is moving independently, so they each have their own
transformation, so the each need to be in a different TransformGroup.

Nope. Compiling a scene is used to optimize a scene to be viewed repeatedly.
You want to just set up your transformations for each frame and let it display.

The user input controls the transforms for the primitives. This is a common
structure for J3D programs.

Yes. If you want display the spheres and cylinders with lights you'll want to
specify GENERATE_NORMALS. See the documentation for
com.sun.j3d.utils.geometry.Cylinder and the parent class
com.sun.j3d.utils.geometry.Primitive.
