Is there a way to automatically determine the correct right vector for the
camera based on the image dimensions specified for the render, so that I
wouldn't have to manually edit the scene file every time I change the
aspect ratio?

Not that commenting out one row is a big chore, but the autoadjust would
be nice. :-)

  AFAIK there's no way to see the command line parameters from the pov code
(except for the clock and clock_delta variables which are the only exceptions).
  I'm afraid that you have to do something like this:

#declare Width=640;
#declare Height=480;

...

camera
{ right x*Width/Height;
  location ...
  ...
}

Having the command line and ini variables available within the scene
language is a feature I'd *really* like to see.

It would be very handy to be able to do things like
camera{
  right x*width/height
  ...
}
and
global_settings{
  assumed_gamma display_gama
}

PoD.
