DESCRIPTION
This program animates a puzzle known as Cube 21 or Square-1. Its moves are chosen randomly.
Cube 21 is a Rubik-like puzzle invented in 1992. Its specialities are that it can change its shape and
even the number of possible moves. It can have more than 200 different shapes and the total number of
configurations (assuming colors) is several tens of billions.
OPTIONS
cube21 accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number
(decimal or hex) of a specific visual.
-delay microseconds
How long to pause between frames. Default is 20000, or 0.02 second.
-texture
Use texture maps. This is the default.
-no-texture
Use solid colors.
-mono Disable both texture maps and colors.
-wireframe
Only draw outlines. Outlines of all pieces, not only the whole object, are drawn.
-spin Spin the whole object around X, Y and Z axes. This is the default.
-no-spin
Do not spin, showing the same three faces all the time.
-wander Move the object around the screen. This is the default.
-no-wander
Keep the object centered on the screen.
-randomize
Shuffle the puzzle randomly at startup. This is the default.
-no-randomize
Do not shuffle at startup, begin at the shape of cube.
-spinspeed number
The relative speed of spinning. Default is 1.0.
-rotspeed number
The relative speed of the moves. Default is 3.0. Setting to ≤ 0.0 makes the object stay at one
configuration.
-wanderspeed number
The relative speed of wandering around the screen. Default is 1.0.
-wait number
How long to stay at ending position after each move. The meaning of the argument is again
relative. Default is 40.0.
-cubesize number
Size of the object. Value of 3.0 fills roughly all the screen (its height). Default is 0.7.
-colormode argument
How many and which colors should the object have. The colors are put on the piece faces so that
the puzzle is solvable. The inner faces are not influenced.
se or silver
Simulate the "Silver Edition" - white and one random color.
2 or two
Two random colors.
ce or classic
Simulate the "Classic Edition" - white, yellow, orange, red, green and blue.
6 or six
Six random colors.
1 or random or rnd
One random color.
Anything else
All faces white.
-fps Display the current frame rate, CPU load, and polygon count.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the
RESOURCE_MANAGER property.
