Hi all....

Recently I have been studying the idea of rendering skies using a model
based on Rayleigh scattering. Some friends recommended POV-Ray as a very
good ray tracing program to use. After a number of weeks on this newsgroup,
a guy called Mark Wagner implemented such a model and he was kind enough to
give me the complete code. To be honest I can't get it to work and I have no
idea how the model was designed. There are alot  of .c and .h files and I
think someone with a good POV-Ray knowledge would probably be able to
understnd how it works.

I have a lot of questions that need answering so I would really appreciate
it if someone could help me out. I don't know if Mark allows me to give the
code to anyone, so if you have genuine interest in looking at it, please
email me back on a.a### [at] ueaacuk and I will send you the code.

Please this is urgent as I have my final exams comming up in 2 weeks time
and I don't  have a lot of time to spend on this.

Thanks

Ammar

  It sounds to me like Mark sent you the program source files for
his patch. If that is the case you will have to compile them as an
executable program before you can run his patch of the program.
You might get someone here to compile it for you and send you the
executable if you don't have a program compiler available to do it
for you.
  Even once you get the source code compiled you are still going to
have to experiment with it to figure out how to use the special
features of the patch. I would think that Mark could at least give
you an example .pov file to work from and maybe a short explaination
of the features of his patch. Since he has not released his patch
publically yet there is no one but Mark who knows how to use it.
This means there is nobody here who can offer any advice to you
on how to proceed or set up your scene file.

I tried to return your e-mail but it bounced back to me so I am posting
my reply here:

Unfortunately I am not a programmer and can't answer these types of
questions for you. You might post a request in .programming asking
for help in getting it compiled. Be sure to specify which OS you are
using. Sorry but that is about the best advice I have to offer.
