• Tool Bars. If you are using the Cortona VRML Plug-in, you should see tool bars around the edge of the window. These tool bars allow to manipulate the image in a variety of ways. (Right click on the image and select 'Help' for detailed information.)
   
• Best Image. If you are using the the Cortona VRML Plug-in, select the "R98 Renderer" and enable all "Anti-aliasing" options. (Right click on the image to view options.) This will produce a smoother image, although the display may be slower.
