问题
I've been looking around the internet for a few days now, and I can't really find an answer that i can understand well enough to rotate my Rubik's Cube.
I have made my own 3D Model using Blender of a Rubik's Cube and imported it in to Unity which is what I'm going to use to rotate the faces.
But I just don't seem to understand the mathematics involved in rotating a Rubik's Cube, should i use Matrices? If so how do i couple it all together for it to work?
I can rotate a single side around by grouping the bricks together by faces, but the moment you turn the next face it would completely disrupt the other one.
Thanks a lot!

My idea: Keep each of the 26 blocks as separate GameObject objects (8 corners, 12 edges, 6 centers), with each block's origin in the center of the cube. Separately you keep track of which block is currently where on the cube, for example in a 3D array.
Then when a face needs to be turned:
- Find out which blocks belong to the face.
- Rotate each of those blocks around the axis of rotation (through the middle of the cube) using Unity's normal rotation functionality.
- Update the information on which blocks are where.
