Rubik::Model

version 0.94

This module is responsible for persisting the state of the Rubik's cube between rotations of sides , and also it maps the set 1..54 to the facelets of the cube.

There is a 3x3x3 array called C that stores the cubies

C[x][y][z] with x,y,z ranging in 0,1,2

It will contain what cube is in that position

A rotation of the front face at 90 degrees clockwise will be like this

0 , 1 , 2 6 , 3 , 0 3 , 4 , 5 ===> 7 , 4 , 1 6 , 7 , 8 8 , 5 , 2

The following correspondence between C and the faces of the cube :

C[x][y][0] is Front C[x][y][2] is Back C[x][0][z] is Up C[x][2][z] is Down C[0][y][z] is Left C[2][y][z] is Right

Each of the cubies will have 1,2,3 facelets visible depending on wether it is a center, a edge or a corner.

This method will reset the cube by multiplying the current state with its inverse.

By doing that the state of the module will become the identical permutation.
