I actually wanted to build a 2x2 rubiks cube. As the Box class in javafx doesn't provide the feature of building a cube with different colours on different faces, I chose to build the cubes using RectangleBuilder to build rectangles with different colours and then applied transformations to build the cubes. But while testing the code I saw that the entire display was coming in a broken manner with the edges overlapping as shown in the picture.
Here is my source code:
