This can prove a real challenge. Radiosity is needed of course in such a scene,
about photons I'm not quiet sure, may be they can add a little bit to the
ambience, but better leave them out for the first WIPs since they are very time
consuming. But most likely you will have light beams visiby falling from the
windows to the earth (or the altar). Then you must use a suitable scattering
media. The radiosity tutorial with the POV-docs is fine, about scattering media
you must do your own experiments (The POV doc is very sparse about it and it can
be hard to find the right parameters, I learned). But feel free to publish your
efforts at the p.b.i (the newsgroup with the name povray-binary-images) and I'm
sure that you will get the one or other comment to help improve your image. But
one of all: you will need patience and a lot of time to accomplish such an
image.
Best regards,
Michael
