title: World space to camera space
body: <p>I am confused on how to convert world space coordinates to camera coordinates.</p>
  
  <p>My current understanding is that I would need to calculate the camera space vector  where</p>
  
  <p>n = eyepoint - lookat</p>
  
  <p>u = up(0,1,0) X n(normalized)</p>
  
  <p>v = n X u</p>
  
  <p>Then once I have &lt; U, V, N > would I simply multiply each point by ?</p>
