Hi,<br><br> I've bought both VTK's books but I didn't found any explanation about<br>some important design aspects of the vtkCamera model considered<br>in VTK.<br><br>I need to know how vtkCamera class implements some theoretic notions
<br>of general camera models. In particular:<br><br>Where is placed or how could I fix a given center of projection?<br><br>Where is located the view plane? In front of or behind the center of projection?<br><br>When the focal distance is changed, Does also the angle of view automaticaly change?
<br><br>Any additional information about this issue will be greatly appreciated.<br><br>Kind regards.<br><br> Jose.<br><br><br><br>
