I am trying to use povray as a "library" for some graphics work I am doing
for my masters thesis.

I am looking for a function somewhat like this:

color ray_trace (ray r);  // takes a ray and returns a color.

Can anyone help me to know if this function exists in the souce?  If so,
what file is it in?

Further, does anyone know if someone has modified povray to do this already?

Thanks in advance,

-Robert

  You can't. POVLEGAL.DOC prohibites this.

Only if you plan to distribute the changes.  If you keep the resulting
binaries and source code to yourself, you can do essentially whatever you 
want to with it, but of course note the disclaimer.

I am not planning on distributing it but only using it myself to help me
with my masters thesis.

There's Trace, defined as

DBL Trace(RAY *Ray, COLOUR Colour, DBL Weight)

in render.c

  Oh, sorry. Then it's ok. As the license says, "What you do with the
software in your own home is your business". :)

Thanks for the help on finding the trace function!

Does anyone know where the function is that loads all the data structures
with the information from the input file?

Yes.

Oh, you actually want to know? :)

Parse(), in parse.c.  But you have lots of initialization and finalization to 
do, too.  See FrameRender, in povray.c, for details.
