hi, folks:

Can anyone tell me what is the ray-tracing algorithm povray uses? Esp.
how povray handles refraction? Your information is greatly appreciated.

best regards.

  Mark, Ming Jiang probably meant the *POV-Ray* unix version source :)

What is the Lions book? The source I downloaded is corrupt. I'll try to
download it again. Thanks.

I was joking.  John Lions wrote a commentary on the source code to Unix
that was published, along with the source code to Unix, for a university
class he taught.  It became quite popular and was often photocopied. 
This was back in the 70's, and it's largely of historical interest at
this point.  The Lions book has since been reprinted, and I have a copy
close at hand.

When you said you had downloaded the "Unix source code," I read that
literally (for the sake of humor) to mean that you had downloaded the
source code to the Unix operating system.
