Gram-Schmidt Process
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 \(N\).
