Here is some working code for rotating the view. The only thing is that it
is inverted. ie. moving left -> rotates right.
ViewPlatform vp = new ViewPlatform();
BranchGroup vpRoot = new BranchGroup();
Transform3D vpTx = new Transform3D();
vpTx.set(new Vector3f(0.0f, 1.0f, 0.0f));
TransformGroup vpTxg = new TransformGroup(vpTx);
* vpTxg.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
* vpTxg.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
MouseRotate mr = new MouseRotate(vpTxg);
mr.setSchedulingBounds(new BoundingSphere(new Point3d(0,0,0), 100));
vpTxg.addChild(mr);
vpTxg.addChild(vp);
vpRoot.addChild(vpTxg);
view.attachViewPlatform(vp);
locale.addBranchGraph(vpRoot);
