Yes, I do. To be blunt, I'm not that young and have not had a geometry
course in several years...I have seen there are a couple books that might
address geometry for computer graphics in general, "Geometric Tools for
Computer Graphics" and "Computer Graphics Handbook: Geometry and
Mathematics" but only have the titles/authors and have not seen the books
in person to know what they cover. Unfortunately, the library system in my
area does not carry too many books on the subject for me to check out for
free before purchasing.

Also, have not seen too many books on ray tracers either that are not the
type that teach you how to make your own (except the ones on Maya). I am
not interested in doing that and also have no guarantee of ever working
with Maya.

Thank you.

Okay...without knowing more about what your level of knowledge is, it's 
going to be very hard to give any advice. The POV-Ray manual explains 
vectors and quite a bit of the math that will be useful in general scene 
building. You said a book "for ray tracing", which is why I suggested a 
book on ray tracers, but if you're interested in the math they use that 
is the best way to go. Making scenes in general really doesn't require a 
lot of math...if you have some specific problems, it would help to know 
what they are.

Thanks for the info.

I am confused by what you mean by the POV-ray manual. Is that help on the
GUI (in the beginning tutorial section)? I have seen this, however, I am
looking for a book (since that will show diagrams of the shapes) esp for
the ones I am not familiar with (spline based and polygon based). No, I
don't have specific problems and this is not an immediate need either.
Actually, the Web site given earlier by greybeard has been helpful too.

Thank you.

Yes

That is in there too, complete with diagrams for many shapes.

Earlier verrsions of POVwin had the manual in a printable format, which I
consider to be several parsecs ahead of html or worse .pdf.  I've printed
out the 3.1 manual and it resides on a music stand next to the computer.
Not everything translates to ver.3.5, but enough that it's still helpful.
Finding an older version and printing out the manual might be helpful,
remembering that there are changes from version to version.

I have an older book, "Ray Tracing Creations" (Chris Young and Drew Wells)
published by the Waite Group Press, includes POV 2.2.  Doubt that it's
available anymore, but this one came from the second hand stores.
(Paperback, think I paid twenty five cents for it, with floppy.)  A lot of
the files posted on the povray groups can be helpful, as well as what's
available from personal websites.  I'm no math whiz, and not having to
reinvent the wheel helps.  I could be wrong, but it seems like 98% of what
anyone would want to do has already been done, and the code posted
somewhere.

Amazon.com has used copies of it listed along with the other POV-Ray books.  
Just search "POV-Ray"

Hmmm.  Wuz pointing out that sometimes a browsing trip through the junk
stores will come up with a real jem that you wouldn't expect to find.  Often
enough to make it worthwhile doing.

Yes, this is the regularized, black and white type of diagrams I was looking
for. Thanks very very much.
