Hi Matias,<br>
<br>
I recommend the "Viewing" chapter of the OpenGL programming guide:<br>
<br>
<a href="http://www.glprogramming.com/red/chapter03.html" target="_blank">http://www.glprogramming.com/red/chapter03.html</a><br>
<br>
It's not specifically about VTK (its for OpenGL, obviously) but it<br>
does a very good job of describing how a camera works in computer<br>
graphics.<br>
