[Visualpython-users] Re: C++ and VPython

Hi, Bruce and all;
Thanks for all the help you've given me in the past, and thanks _especially_
for ' scene.stereo='crosseyed' '.

In order to speed up my program, I'm recoding it in C++ (and estimating
about 40 times speed increase over Python), which I know very little about
(but am slowly fighting my way through the molasses...).

VPython gives me my views into my Python program's calculation space, and I
can watch my points packing themselves.  To do the same with C++ is going to
take _way_ more knowledge of C++, Windows (microsoft's) and probably OpebGL,
than I'm likely to obtain in my lifetime (which by now is not what it was
when I was young (*g*)).

The program itself is mostly vector math, which I'm fighting into submission
now, and since I've got all the rest of the needed functions (randomizings,
file readings/writings, database makings (dynamic arrays versus lists and
dictionaries etc.) and user input/output handled in the C++ version, all I'm
going to be facing soon is visibility into my calculation space.

Hence the query: is there any way to interface my C++ _calculation_ system,
with VPython's OpenGL operations or with VPython itself, so that I can use
(a modified version of) what I already have with VPython, to do the
lookings-in-to what the C++ calculation program is doing?

IOW, can I call out from within the C++ program, to the VPython
visualization system?

Thanks!

Peace
JB
