Rubicks_Cube

Here this rubicks cube project is done using Processing. As we are making it as a 3D rotation cude ... we are using PeasyCam to get the visualization.

we will be creating a Matrix to take and move for every perticualar position..

PMatrix3D matrix;
  int x = 0;
  int y = 0;
  int z = 0;
  color c;
  Face[] faces = new Face[6];

and the faces having thier possible chances of respective color:

faces[0] = new Face(new PVector(0, 0, -1), color(0, 0, 255));
faces[1] = new Face(new PVector(0, 0, 1), color(0, 255, 0));
faces[2] = new Face(new PVector(0, 1, 0), color(255, 255, 255));
faces[3] = new Face(new PVector(0, -1, 0), color(255, 255, 0));
faces[4] = new Face(new PVector(1, 0, 0), color(255, 150, 0));
faces[5] = new Face(new PVector(-1, 0, 0), color(255, 0, 0));

for every move when the face is turned.. it has to turn around by 90 degress..

void turnFacesY(int dir) {
  for (Face f : faces) {
    f.turnY(dir*HALF_PI); 
  }
}

this 3DPMatrix should be continuously updated for every change in face or in move... these are the so called every possible move that the perticular pixel can take:

Move[] allMoves = new Move[] {
new Move(0, 1, 0, 1), 
new Move(0, 1, 0, -1), 
new Move(0, -1, 0, 1), 
new Move(0, -1, 0, -1), 
new Move(1, 0, 0, 1), 
new Move(1, 0, 0, -1), 
new Move(-1, 0, 0, 1), 
new Move(-1, 0, 0, -1), 
new Move(0, 0, 1, 1), 
new Move(0, 0, 1, -1), 
new Move(0, 0, -1, 1), 
new Move(0, 0, -1, -1) 
};

and after each turn the colors that were once on one side have to now Translated to another side to taht respective turn.. so as per that turn the function should command to rotate by 90 degrees and also to translate them:

void turnX(int index, int dir) {
  for (int i = 0; i < cube.length; i++) {
    Cubie qb = cube[i];
    if (qb.x == index) {
      PMatrix2D matrix = new PMatrix2D();
      matrix.rotate(dir*HALF_PI);
      matrix.translate(qb.y, qb.z);
      qb.update(qb.x, round(matrix.m02), round(matrix.m12));
      qb.turnFacesX(dir);
    }

In this way check out the code and run it for yourself...
