It should be possible without modifying the source. You know the ray 
direction for each pixel, the only piece of information you are missing 
is the depth. This can be found by either using megapov (IIRC) to output 
the depth image, or using a special gradient texture in the standard POV 
that will output a colour depending on the depth.

Unless you are familiar with the POV source (or want to become familiar) 
then I'd say the above option will be easier to implement.
