[vtkusers] what is vtkCamera's field of view?

[Amy Squillacote]

Hi Mark,

Is your vtkCamera using parallel or perspective projection? (You can use 
the GetParallelProjection() method to find out.) If the vtkCamera is 
using parallel projection, then use the GetParallelScale() method; 
otherwise use the GetViewAngle() method. The on-line documentation for 
vtkCamera (which contains a descriptions for both of these methods) is 
here: http://www.vtk.org/doc/nightly/html/classvtkCamera.html.
