A way for calculating the coordinate axes \((N,U,V)\) for cameras view coordinate system.

We define \(N\) arbitrarily based on some point in the world-coordinate system we want to look at.

For the remaining axes \(U,V\) we [see page 8, try] to define \(U\) such that it's close to Y. So we:

  • Guess a \(U\), \(U'\), and use that to find \(V\) such that \(V\) is perpendicular to \(N\).
  • Find a \(U\) that's perpendicular to \(V\) and \(N\).
