Finding Touching Faces Based on Rotation for Cubes in 3D
I have this pretty specific problem that I haven't been able to find an answer to. I tried googling it but I'm not really sure what I should look for.
The problem: Cubes have 24 possible rotations in 3d where they line up with the original (24 possible rotations by increments of 90 degrees). If I have two cubes that are touching, where they can be touching each other on any face (above, below, on the right, etc.), and they both are rotated by some multiple of 90 degrees, based on their positions and their rotations how can I efficiently tell which two faces will be touching, and the relative rotation of those faces? 
in this example, side 6 would be touching side 6, where the second is cube rotated 90 degrees relative to the first.
Side question, if I know that these objects will be at 90 degree rotations, what data type should I use? (quaternions seem pretty big for what I'm doing)
Hi, I have the same problem. If you found the answer, can you help me to solve?
You might just assign a gameObject to each side of a cube with a small collider plus a tiny script that simply contains the assiociated eye count of that side. Then check for overlapping colliders. From overlapping colliders, get the script with GetComponent and read out the assigned eye count. If you position the collider-gameObjects so that their local "up" is pointing away 90° from the surface of the respective side you should be able to measure their relative rotation to each other by comparing the 'y' value of their transform.localEulerAngles.
That said, I gave this interesting problem a try with another approach and built a small test environment that you can check for yourself here ->>: diceGit
