POV is written in C. Not C++.
Anyways, it appears the folks at SIGGRAPH are busy putting together a
ray-tracing information site. (Which is good since there's so few out
there):
http://www.education.siggraph.org/materials/HyperGraph/raytrace/rtrace0.htm
There's also lots of ray-tracing related material in the Graphics Gems
archive,
and there are other, simpler raytracers than POV out there with source. (DKB
Trace,
MTV, Rayshade, etc.)
You should also hunt down an archive of Eric Haines' 'Ray-Tracing News'
which has carried tons of pointers to code, ideas, algorithms and the like
for over a decade now. There is also some code and info on Dr Dobbs website.
There is also the newsgroup: news:comp.graphics.rendering.raytracing (whose
FAQ lists many, many resources and sources) and
news:comp.graphics.algorithms (ditto) where there are *many* people who can
help, many of whom are very much experts and pioneers in the field to boot.
Ray-tracing is just a little geometry sprinkled with algebra. (There exists
one that can be printed on a single 3X5 index card, written in postscript of
all things.)
Anyways, these are some ideas to help you in your searching, good luck.
