Detailed Description

Camera class.

Represents a camera matrix, consisting of a position, three vectors, and a zoom level. Following convention, the Z vector points backwards (i.e. towards the observer, from the scene), the Y vector points up (i.e. towards the top of the screen), and the X vector points right (i.e. the right side of the screen). Pictorially:

  |Y
  |
  P----X
 /
/Z

Where the observer (at position P) is looking along the direction opposite Z, with Y and X defining the orientation of the viewing frustum. The 3x4 camera matrix is simply [X,Y,Z,P].
