Re: [JAVA3D] Mouse Zoom does not work with PARALLEL_PROJECTION?

Yes there are two methods I know of that will let you perceive the zoom in a scene with parallel projection: One way is to resize your BranchGroup using a TransformGroup. The other way is to change your screen size, something like this: public void changeZoom(double scale) { Canvas3D c = vi
