+ Users can use the following keys to control the view
+
+ The following four key combinations can shift the view correspondingly,
+ function in both stereo and normal mode.
+ Ctrl+left arrow
+ Ctrl+right arrow
+ Ctrl+up arrow
+ Ctrl+down arrow
+
+ F (captital letter) shift the camera far from objects
+ N (captital letter) shift the camera near from objects
+ S (captital letter) toggle between normal and stereo mode
+ I (captital letter) increase the distance between two views
+ D (captital letter) decrease the distance between two views
+
+ if the Key function defined by user maps any key appearing above, it will be
+ masked by the program. Hence, user should either modify his own code or
+ modify function defaultKeyProc at the end of this file
