Yeah, I'll work on a patch on my end.

The 3D scene gets created that reflects what the OpenMap map projection
currently is.

Not really. It just something I created to clean up the appearance of
the scene. OpenMap relies on natural Java clipping to cut off the
extents of what is on the map. In Java 3D, it turns out that the
overhang still gets rendered into the scene, you you end up with partial
OMGraphics getting scattered around (on the other side of the curtain).
The curtain is just an object covering up the untidiness.

Right now it's a box, but I think different shapes would be useful, like
a picture frame kind of thing.

You might want to run with -Ddebug.3dshape for more details when actual
3DShape objects get created for the scene, just to make sure that step
is happening.
