Thank you for sharing this. It's very interesting for me, because it
gives me a little insight into Java3D.

I would change the behaviour of the mouse dragging. In your version the
scene rotates to the left when the mouse is dragged to the right and
vice versa. I don't know whether this was intended or not.

I would change two lines in the mouseDragged method:

public void mouseDragged(MouseEvent event){
	int dx = event.getX() - iMouseX;
	int dy = event.getY() - iMouseY;
	iMouseX = event.getX();
	iMouseY = event.getY();			

/* old: fRotX += (float)dy/150f;*/
	fRotX += (float)-dy/150f;
/* old:	fRotY -= (float)dx/150f;*/
	fRotY -= (float)-dx/150f;

	fRotX = (float)Math.min(0.15f,fRotX);
	fRotX = (float)Math.max(-Math.PI/2,fRotX);
	repaint();
}

Just my 2 eurocents.

So long,

Bonsai
