Emmanuel,
Thanks so much for the quick response to my question.
Unfortunately, I'm an *infant* newbie. I found out
that a shell is something in Unix using the Terminal
application (?I could be wrong?) and have a vague idea
what an ARB Fragment program is.
Not too long ago, I downloaded some sample GLUT
programs in an XCode project file. There were about 7
or so targets: one had whales swimming around, another
an animated chessboard, etc. I was able to examine and
compile the source code for each one and hardly had to
figure anything out.
It seems (and again, I could be wrong) that I should
be able to incorporate my Cg tools into XCode (see the
Cg Toolkit from NVidia's Web site) so that I can enter
and compile the example source code listings in the Cg
Tutorial book. It's a beginner's book that explains Cg
as if you were learning C or C++.
I hope I have given you enough information and
apologize in advance if I've gotten anything wrong. If
you or anyone else on the list knows what I'm talking
about and can post some suggestions, I'd be eternally
grateful and I can stop pulling my hair out.
In the meatime, I'm going to look at as much as I can
find out about Unix, C, C++, GLUT, etc. . . .
Thanks again for your help.
Peter
