I need a bit of help with the focal blur module. I am trying to render a simple
scene with 3 vertical bars in the front and 3 horizontal ones at the back. I'm
having trouble with setting the focal length in the scene (focal_point does not
seem to work for this). All the scene parameters (for eg. distances of objs from
camera, their thickness etc.) are in terms of focal length. How do I set it as a
param and use it to define all other distances? Also generally aperture in
cameras is defined as a fraction of 'f'. How does the aperture param in POVRay
correspond to real apertures defined as such?

Another doubt: As I am trying to increase the aperture and putting my
focal_point on the vertical bars in the front (ref: images in the ZIP), the bars
at the back start "splitting" into parts. Any thoughts on how this could be
happening?

Thanks in advance!
