REQUIREMENTS:

3DCUBE needs a 286 (or higher) PC or compatible with color VGA.  Mouse is
optional, but highly recommended.


DESCRIPTION:
	
3DCUBE is the best 3D cube puzzle available.  It features high resolution
graphics with very smooth, three-dimensional animation.  It operates exactly
like the real cube puzzle, which is sold in many toy stores.  This program
also displays a 2D layout across the top of the screen so that all sides
can be viewed at once.

Start by having the computer mix up the cube.  Each face of the cube may
be rotated to change the position of the colors.  It is up to the user
to move the colors back to their original positions, so that each face of
the cube contains only one color.  It is actually easier than it appears!

The entire cube may be rotated about the x,y, or z axis.  To rotate
counterclockwise (as viewed from the top/left) press x,y, or z on the
keyboard.  Or, with a mouse, click with the cursor on the appropriate button
displayed above the cube.  To rotate clockwise use Capital X,Y, or Z or
click with the right mouse button.

To rotate a cube face counterclockwise, press the number printed below the
2D display of that particular face.  (Note:  the center color never changes.
Therefore, "1" always turns the face with the blue center, etc.)  If using a
mouse, click with the cursor directly on the 2D display of the face you wish
to turn.  To turn clockwise, use shift with the number on the keyboard or
use the right button of the mouse.

All rotation is done in relation to the cube, not the monitor.  Therefore,
if the back side of the cube is rotated clockwise it will appear to rotate
counterclockwise.

Good Luck!

ABOUT THE PROGRAM:

3DCUBE was written entirely by Warren Ward using Borland Turbo C++ 3.0 with
a large amount of inline assembly.

The non-standard 320x400x256 video mode was chosen for three reasons:

   1) 3DCUBE uses two full screen pages for smooth animation.
   2) I needed a black that was "not really black" (color 16) for
      "invisible border" fills.  (Others are used also.)
   3) It is the highest VGA resolution that satifies both #1 and #2.

Because the video mode is non-standard, it was necessary to create a full
library of graphic functions.  These were all written as inline assembly
routines for maximum speed and minimum size.  For the same reasons, all
printing functions are inline assembly creations as well.

The cube itself does NOT consist of a series of matrices defining the
borders of several objects, as is typical.  For this program, that method
would have been significantly slower.  I leave it to you to figure out how I
really did it.
