Description
-----------
3DVBE is a very simple program.  It uses the VESA SuperVGA BIOS (VBE)
version 1.1 or higher.  It displays a simple stereo Moire pattern
in any 256-color VBE mode.  It also will list the available VBE modes.

Running 3DVBE
-------------
Before running 3DVBE, be sure to load your VBE or VESA driver, if it is
not built into your hardware.  You can also load other (newer) versions of
VBE even if you have an older version of VBE built into your hardware.
One source of such a driver is UniVBE from SciTech Software.  If no
VBE driver is present, 3DVBE will complain and exit without doing anything.

*After* loading your VBE driver, you should also load LCDBios if you
want to see the Moire pattern in stereo.  You should never load a 
VBE driver after loading LCDBios.

There are 2 ways to run 3DVBE.  If you just run
  3DVBE
then the VBE version and a list of valid 256-color VBE modes is
presented.  Any of these VBE modes can be used in 3DVBE.

To see the stereo Moire pattern, run
  3DVBE xres yres
where xres and yres are the resolution that you wish to use.  For example,
  3DVBE 640 480
runs the demo in 640x480 in 256 colors.  When running 3DVBE, first the
left-eye image will appear.
  Press any key.
Then the right-eye image should appear.  Notice that the center point of
the right-eye image is slightly different from the center point of the
left-eye image.
  Press any key.
After a short (1-second) delay, LCDBios will activate.  You should
see the image in stereo (3D).  The edges of the image should appear
on the screen, while the center of image should appear to be behind
the screen.
  Press any key.
LCDBios will deactivate, and the left-eye image will be displayed.
  Press any key.
The program deactivates and returns to DOS.

After running 3DVBE, don't forget to type "exit" at the DOS prompt
to remove LCDBios from memory.
