title: Getting the axis pointing up in a rotation (Unity)
body: <p>I have an object in unity which has a rotation described as the following:
  x, y, z, where they are both rotations ranging from 0 to 360 around their respective axis.</p>
  
  <p>Now I'm trying to find out which of the vectors point up the most. Essentially I have a 6-sided dice, on which I use physics to emulate a dice-throw. I now want to find out which of the 6 faces of the die points upwards. I can imagine some rather advanced if sentences, revolving around checking the rotations individually, but I'd like to know if there is a good way to do this?</p>
