[vtkusers] vtkCamera as X-Ray camera

[Taylor Braun-Jones]

Hello vtkusers,

I'm trying to position and orient a vtkCamera to model an X-Ray camera as
shown in the figure below.

[image: Inline image 1]

I'm running into uses so I just want to make sure this is fundamentally
possible with a vtkCamera. I know:

 - Position and orientation of the camera coordinate system (red axes) in
world space
 - X-Ray point source (green point)
 - Principal point (purple point)
 - The width, d, of the square detector (and therefore the view angle)

(1) Can I place Props between the camera Position and FocalPoint?

(1a) If so, how should the Position and FocalPoint be set?

(1a) If not, is there another approach to set the
Position/FocalPoint/ViewUp to simulate this?

Thanks!
Taylor
