DESCRIPTION
The original puzzle has 9 squares per face (size = 3). The puzzle was designed by Erno
Rubik and called the Rubik's Cube. This has 8!*12!*3^8*2^12/12 or 4.3 * 10^19 different
combinations.
The Pocket Cube has 4 squares per face (size = 2) also designed by Erno Rubik. This has
7!*3^6 or 3,674,160 different combinations.
Rubik's Revenge has 16 squares per face (size = 4) also designed by Erno Rubik. This has
7!*3^6*24!*24!/(4!)^6 or 7.4 * 10^46 different combinations.
5x5x5 Cube. This has 8!*12!*3^7*2^10*(24!)^3/(4!)^12 or 2.83 * 10^74 different
combinations.
There is also the Magic Domino 3x3x2 cube which has (8!)^2/4 or 406,425,600 combinations.
A physical 6x6x6 cube is possible but to my knowledge no one has been too successful in
building one. 7x7x7 is also possible, but here one must make the center most cubes
smaller than the outside cubes, so the corners do not fall off when turned.
FEATURES
Press "mouse-left" button to move a piece. Release "mouse-left" button on a piece on the
same face and in the same row. The pieces will then turn towards where the mouse button
was released.
Click "mouse-center", or press "P" or "p" keys to toggle the practice mode (in practice
mode the record should say "practice"). This is good for learning moves and
experimenting.
Click "mouse-right", or press "Z" or "z" keys, to randomize the puzzle (this must be done
first to set a new record).
Press "R" or "r" keys to read a saved puzzle.
Press "W" or "w" keys to save (write) a puzzle.
Press "U" or "u" keys to undo a move.
Press "E" or "e" keys to redo a move.
Press "C" or "c" keys to clear the puzzle.
Press "S" or "s" keys to start auto-solver. Only works on 1x1x1, 2x2x2, and 3x3x3 cubes.
Press "O" or "o" keys to toggle the orient mode. One has to orient the faces in orient
mode, besides getting all the faces to be the same color. To do this one has to get the
lines to be oriented in the same direction, this only matters with center piece, if at all
(i.e. those pieces not on a corner or edge). This does add complexity so there are 2
sets of records.
Press "I" or "i" keys to increase the number of pieces.
Press "D" or "d" keys to decrease the number of pieces.
Press "x" key to increase the number of pieces along the x axis.
Press "X" key to decrease the number of pieces along the x axis.
Press "y" key to increase the number of pieces along the y axis.
Press "Y" key to decrease the number of pieces along the y axis.
Press "f" key to increase the number of pieces along the z axis.
Press "F" key to decrease the number of pieces along the z axis.
Press "V" or "v" keys to change the view of the cube.
Press ">" or "." keys to speed up the movement of pieces.
Press "<" or "," keys to slow down the movement of pieces.
Press "@" key to toggle the sound.
Press "Esc" key to hide program.
Press "Q", "q", or "CTRL-C" keys to kill program.
Use the key pad or arrow keys to move without the mouse.
Key pad is defined for the Rubik2d as:
/ Counterclockwise
8 Up
^
4<5>6 Left, Clockwise, Right
v
2 Down
Key pad for other than Rubik2d, use must use your intuition (is this a cop out or what?).
The key pad is defined differently depending on which side of the cube your mouse is
pointing at. One thing that stays the same is "5" is Clockwise and "/" is
Counterclockwise.
Use the control key and the left mouse button, keypad, or arrow keys to move the whole
cube. This is not recorded as a turn.
The title is in the following format (non-motif non-opengl version):
xrubik{2|3}d<dimension>: {1|2|3|4|5|6<cubes per edge on x-axis>x{1|2|3|4|5|6<cubes
per edge on y-axis>x{1|2|3|4|5|6<cubes per edge on z-axis>} @ (<Number of
moves>/{<Record number of moves> <user name>|"NEVER noaccess"|"practice"}) -
<Comment>
If there is no record of the current puzzle, it displays "NEVER noaccess".
OPTIONS
-geometry {+|-}X{+|-}Y
This option sets the initial position of the rubik window (resource name
"geometry").
-display host:dpy
This option specifies the X server to contact.
-[no]mono
This option allows you to display the rubik window on a color screen as if it were
monochrome (resource name "mono").
-[no]{reverse|rv}
This option allows you to see the rubik window in reverse video (resource name
"reverseVideo").
-{foreground|fg} color
This option specifies the foreground of the rubik window (resource name
"foreground").
-{background|bg} color
This option specifies the background of the rubik window (resource name
"background").
-face{0|1|2|3|4|5} <color>
This option allows you to change the color of a face (resource name "faceColorN").
In mono-mode, color is represented as the first letter of the color name. On the
2-D version, the faces are ordered top to bottom and left to right on the "t"
configuration. The sideways "t" or "+-" configuration is physically consistent
with the former, so it is ordered "0, 1, 2, 3, 5, 4". If you has two colors that
begin with the same letter you should have one in uppercase and one in lowercase
to distinguish them in mono-mode. You can change the colors of the faces to make a
stupid cube (i.e. all White or in mono-mode all "W"). Unfortunately, it will not
normally say its solved when its randomized. This would be cheating.
-{border|bd} color
This option specifies the border color of the pieces in the rubik window (resource
name "borderColor").
-delay msecs
This option specifies the number of milliseconds it takes to move pieces (1-50)
(resource name "delay").
-[no]sound
This option specifies if sliding pieces should make a sound or not (resource name
"sound").
-moveSound filename
This option specifies the file for the move sound the twisting of the puzzle
(resource name "moveSound").
-{font|fn} ontname
This option specifies the font that will be used (resource name "font").
-view <int>
This option allows you to change the view of the cube for OpenGL with choice of 4
views (resource name "int").
-sizex <int>
This option allows you to change the number of pieces on a edge along x-axis
(resource name "sizex").
-sizey <int>
This option allows you to change the number of pieces on a edge along y-axis
(resource name "sizey").
-sizez <int>
This option allows you to change the number of pieces on a edge along z-axis
(resource name "sizez").
-[no]orient
This option allows you to access the orient mode (resource name "orient").
-[no]practice
This option allows you to access the practice mode (resource name "practice").
-userName string
This option specifies the user name for any records made or else it will get your
login name (resource name "userName").
-scoreFile filename
Specify an alternative score file (resource name "scoreFile").
-scores This option lists all the recorded scores and then exits.
-version
This option tells you what version of xrubik you have.
RECORDS
You must randomize the puzzle before a record is set, otherwise an assumption of cheating
is made if it is solved after a get or an auto-solve.
SAVE FORMAT
Here is the format for the xrubik configuration, starting position, and the movement of
its pieces. The format is not standard. The reason is that this is simple to produce and
the standard notation is no good for variable number of pieces.
Rubik2d with default colors, not randomized (front is face 2) :
0 R Red
1 2 3 Y W G Yellow, White, Green
4 O Orange
5 B Blue
sizex: 1-6 <the number of cubes per row along x-axis>
sizey: 1-6 <the number of cubes per row along y-axis>
sizez: 1-6 <the number of cubes per row along z-axis>
orient: 0-1 <0 false, 1 true; if 1 then lines on pieces to be oriented>
practice: 0-1 <0 false, 1 true>
moves: 0-MAXINT <total number of moves>
startingPosition: <2 dimensional array of face and piece position, each face has
size1 * size2 pieces, if orient mode then orientation number follows face number: 0
up, 1 right, 2 down, and 3 left>
This is then followed by the moves, starting from 1.
move #: <face> <position> <direction> <control>
Each turn is with respect to a face and position.
Position is 0 to size * size - 1. Position 0 is in the upper left.
Direction is represented as 0 up, 1 right, 2 down, 3 left, 5 clockwise, and 7
counterclockwise.
Control is represented as 0 or 1, 1 if the whole cube is moved at once (here position does
not matter), 0 if not. The xrubik record keeper does not count a control move as a move,
but here we do.
If you have a Rubik's Cube you can not solve (2x2x2 or 3x3x3) enter it in rubik.log file.
Have size = 2 or 3, orient = 0, practice = 0, randomized = 1, and moves = 0 and the number
representation for the color of the piece (usually 0=R, 1=Y, 2=W, 3=G, 4=O, 5=B). Bring
up xrubik, hit 'g' so it will get your configuration and then 's' to solve your cube and
then 'w' to write out the steps. Then examine your rubik.log file.
