RubicsCube with OpenGL

A fully playable 3D rubicscube that you can control with your keyboard.

It uses OpenGL with GLFW, with GLAD and with GLM for the 3D world representation.

Controls

Moving around the cube:

• A,D : left and right
• S,W : back and forward
• J,K : bottom and top

Selecting the current-face

• The current face is drawn by a lighter cube in its center
• Use '1', '2', ..., '6' to pick a face

Moving the cube itself uses the same notation as for real rubicsrube

• F : moves the Forward face clockwise
• R : moves the Right face clockwise
• U : moves the Up face clockwise

To move counter-clockwise, press 'SHIFT'.

Compilation

This project uses CMake as a compilation tool.

mkdir build
cd build
cmake ..
make

But it has some dependencies (that I have not yet setup using git submodules).

Behind-the-Scene

This project is yet another simple project to learn yet another programming concept: OpenGL.

The model of the rubicscube is in rubicscube.cpp. Each of the 26 cube is represented by a Cube object, which contains a transform (translation & rotation).

How to find which cube to move ?

I have to find a geometrical transform to always obtain a rule.

The centers have the following coordinates. They will never change.

• white = ( 0, 0, 1)
• orange = ( 0, 1, 0)
• blue = ( 1, 0, 0)
• green = (-1, 0, 0)
• yellow = ( 0, 0,-1)
• red = ( 0,-1, 0)

Each other cube can be attached to any of the following centers. There is a function that given a cube, returns the colors of the centers next to it. We could look at the distance at each center.
