1. When using the command #DEBUG where can I access the output? Or where is
it displayed?

2. Is there a way to extract the pixel coordinate for specific location
using the mouse over it and clicking? Then store these points in a file?

3. How can I display the same object viewed with 2 different cameras with

uncomment the other camera and then render it again?

4. How can I obtain the camera parameters such as focal length, etc?

Many thanks

  Depends on which OS you are using. In the windows version every #debug
line is output to the messages window.
  You can also use the +G option to redirect it somewhere else.

  You can make a two-frame animation where you have something like
this:

#if(clock = 0)
  camera { ... }
#else
  camera { ... }
#end

  You can't. At least not in the current POV-Ray (version 4 will probably
have means to do that).

You can: All you have to do it compute them yourself based on the values you
set the camera to.  The equations (or details about them) and default values
are in the documentation.

I was going to ask that question because my camera settings are created by

is good to know all I need to do is wait:-}

before. :-}
Thank you Rumour Control. :-}

something like digital graph paper?

I don't think this is related directly to the POV-Ray program, but I assume
you want to do it for something like spline, lathe, or sor creation? In that
case there probably are stand alone applications for this. I havn't use
Moray for a while, but it had such a thing (sort of) but more robust.

Thanks for the reply. What keyword I need to search for?  I've tried Index
seaech for (focal length, calibration, camera parameteres, intrinsic, pixel
) but to no avail?

camera

(remember that you have to click on it once displayed - the second blue box
on that page shows the default values for the default camera).
