Printing out VRML image on Windows and Unix/X-Window

Windows users can print out your VRML image in the following way: 

• make the viewer window active (by clicking on anywhere on the viewer window)
• type [Alt]+[PrintScreen] -- this will capture the screen image to the clipboard
• paste the image on the clipboard into a Word document, PowerPoint, or any image/graphics editors -- this can be done by [Ctrl]+[v], or by the "paste" command under the "edit" menu.

Unix/X-Window users can use the "xv" command to capture a screen image.
