[vtkusers] ActiViz | Camera Set Position

[David Gobbi]

Hi Matias,

I recommend the "Viewing" chapter of the OpenGL programming guide:

http://www.glprogramming.com/red/chapter03.html

It's not specifically about VTK (its for OpenGL, obviously) but it
does a very good job of describing how a camera works in computer
graphics.
