Rotating faces Rubik's Cube C#

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

Mr. Dum: Hello, I'm very stupid but I still want to solve a 3x3x3 Rubik's cube. Mr. Smart: Well, you're in luck. Here is guidance to do just that! Mr. Dum: No that won't work for me because I'm Dum. I'm only capable of following an algorithm like this. pick up cube look up a list of moves from some smart person while(cube is not solved) perform the next move from list and turn the cube as instructed. If there are no more turns in the list, I'll start from the beginning again. hey look, it's solved! Mr. Smart: Ah, no problem here's your list! Ok, so what sort of list would work for a problem

What would be a relatively easy algorithm to code in Java for solving a Rubik's cube. Efficiency is also important but a secondary consideration. ire_and_curses The simplest non-trivial algorithm I've found is this one: http://www.chessandpoker.com/rubiks-cube-solution.html It doesn't look too hard to code up. The link mentioned in Yannick M.'s answer looks good too, but the solution of ' the cross ' step looks like it might be a little more complex to me. There are a number of open source solver implementations which you might like to take a look at. Here's a Python implementation . This Java

Visually correct rotation with OpenGl and touch screen capabilities

问题 I have been trying to do Cube of Rubik for android. I have one question about rotations. I want to rotate a figure visually correct. It means if user touch screen and after move his finger to right a figure rotate to right from side of observation point. But when I make some rotations the figure start move in not correct direction. I understand that it depends on that axis are change their situation. But I tried to use inverse model matrix to get necessary coordinates, but I haven't already

问题 If you were developing software to solve a Rubik's Cube, how would you represent the cube? 回答1: This ACM Paper describes several alternative ways that it has used to represent a rubik's cube and compares them against eachother. Sadly, I don't have an account to get the full text but the description states: Seven alternative representations of Rubik's Cube are presented and compared: a 3-by-3-by-3 array of 3-digit integers; a 6-by-3-by-3 array of literals; a 5-by-12 literal matrix; an ll-by-ll
