 16            <meta name='description' content='Test Transform scaling effect on Fog visibility. This world contains two Viewpoint nodes, residing in two seperate Transforms. One Viewpoint is contained in a Transform with a scale of 1 1 1. A second Viewpoint is contained in a Transform with a scale of (.01 .01 .01). Indicating the Text geometry associated with each Viewpoint places the viewer in that Viepoints local coordinate system. A single Fog node with a visibilityLimit of 40 meters, and Box geometry exist in the root Transform. Indicating the appropriate Text geometry with the pointing device moves the Viewpoint to either of the two Transforms local coordinate systems. As a result: indicating the left Text geometry places the Viewpoint at a distance of 20 meters from the Box, while indicating the right Text places the Viewpoint in a local coordinate system where the viewer is 2000 meters from the Box. Hence, indicating the left Text results in a half-fogged Box, while indicating the right Text renderes a fully-fogged Box.'/>
