README.md

• Modelling Rubik’s cube in python.
• Rendering the cube in 3D.
• Rotating the cube in 3D based on user input from keyboard and mouse.
• Visualising the rotations and moves of the cube.
• Animating transitions accompanying rotations.
• Automate solving rubik’s cube by computer using known algorithms.

L is for rotating LEFT face. R is for rotating RIGHT face. U is for rotating UP face. D is for rotating DOWN face. F is for rotating FRONT face. B is for rotating BACK face.

X is for rotating about RIGHT axis. Y is for rotating about UP axis. Z is for rotating about FRONT axis.

SHIFT is for anti-clockwise rotation, by default clockwise rotation. CTRL is for moving two layers together.

mouse drag is for rotating the cube. ←, ↑, →, ↓, [, ] for rotating the cube using keys.

S is for saving current cube spatial orientation. I is for resetting the cube spatial orientation to previously saved orientation.

H is for randomly shuffling using 50 steps. J is for solving till the next step. K is for solving the entire cube. Pressing SHIFT along with the above keys visualizes the moves.

ESC and Q for quiting the simulation.

README.md

Py222 is a 2x2x2 Rubik’s Cube representation written in Python. It has support for applying individual moves to the puzzle, as well as space-separated algorithm strings specified in WCA notation.

A cube’s state is represented as a 24-element numpy array with indices corresponding to the following stickers, and values corresponding to the following face colors:

sticker indices: ┌──┬──┐ │ 0│ 1│ ├──┼──┤ │ 2│ 3│ ┌──┬──┼──┼──┼──┬──┬──┬──┐ │16│17│ 8│ 9│ 4│ 5│20│21│ ├──┼──┼──┼──┼──┼──┼──┼──┤ │18│19│10│11│ 6│ 7│22│23│ └──┴──┼──┼──┼──┴──┴──┴──┘ │12│13│ ├──┼──┤ │14│15│ └──┴──┘ face colors: ┌──┐ │ 0│ ┌──┼──┼──┬──┐ │ 4│ 2│ 1│ 5│ └──┼──┼──┴──┘ │ 3│ └──┘ 

The move definitions are written for a sticker representation, but there are functions to normalize the state’s stickers relative to a fixed DLB corner, and convert it into a fixed-corner piece orientation and permutation (OP) representation. There are also various functions that can hash the fixed-corner OP representation state into unique integer indices.

Also included is a sample IDA* solver (solver.py).

README.md

PyCuber is a Rubik’s Cube package in Python 2/3

The cube can be revealed as expanded view in the terminal, so it’s easy to visualise the cube, just inside the terminal. (Not tested on Windows)

import pycuber as pc # Create a Cube object mycube = pc.Cube() # Do something at the cube. mycube("R U R' U'") print(mycube)

We also provided some useful tools to deal with Rubik’s Cube formulae.

import pycuber as pc # Create a Formula object my_formula = pc.Formula("R U R' U' R' F R2 U' R' U' R U R' F'") # Reversing a Formula my_formula.reverse() print(my_formula) # Mirroring a Formula object my_formula.mirror("LR") print(my_formula)

F R U' R' U R U R2 F' R U R U' R' F' L' U L U' L' U' L2 F L' U' L' U L 

I’ll add some documentations later.
