We have code that has one way of doing this in NCSA Portfolio's Display
program, which we include as source in the download:
BranchGroup group = new BranchGroup();
group.setCapability(Group.ENABLE_PICK_REPORTING);
BoundingSphere bounds = new BoundingSphere(new
Point3d(0.0,0.0,0.0),2000000.0);
Color3f bgColor = new Color3f(0.17f, 0.65f, .92f);
Background bg = new Background(bgColor);
bg.setApplicationBounds(bounds);
group.addChild(bg);
Don't worry about the Group.ENABLE_PICK_REPORTING. It's for another part of
the app.
