Life after the scenegraph

[uj]

I'm considering JOGL (instead of Java3D or Xith3D) because I feel maybe I can do without the overhead of a scenegraph. My 3D model is quite simple.

So my question is how low-level is JOGL in relation to the scengraph based packages? What will I be missing; lightning, picking of objects, rotating the scene, user input from keyboard/mouse, primitive objects like sphere, cone, zylinder, text etcetera. Will it be much work to recreate with JOGL the convenient infrastructure (outside the actual scenegraph) I've become accustomed to?
