Do try to get it into OOP when you have some (long, lol) spare
moments. Matrices, vectors etc really do very well in an OOP
environment.

Damn, indeed, it doesn't run in my Win2K. Just gives 6 little dots
after inputting XYZ. I'll try it under Win95 later.

Yeah, I'm sure it'll take at least a week or two lol!!! See you in a couple
years! It took me about 6 months to write the program on my website, and that
was my first Windows program (aside from little monkeying around stuff to see
how things work.) The physics that went into that were ported from an old DOS
QBasic program I wrote, so it took MUCH longer to figure out. OOP? That'll
take a while... :-)

Sorry, it's because I don't handle drawing properly (through WM_Paint
messages), rather, it uses WM_Timer. That doesn't seem to work in Win2K. I
think it does in Win ME, though. Anyway, let me know if it looks right. Do
objects really do wierd things like that when they're spinning in 0g? Bizarre!
Not sure if it's right.

Weird, WM_TIMER works in Win2K though. Perhaps you're not handling
BeginPaint()/EndPaint() things right. Well, I don't know much Windows
programming actually, so I can't really tell.
Perhaps you should call Invalidate() on the window instead of painting
from within WM_TIMER. (and process the WM_PAINT message, this is not
really a message at all I believe, more a state which is sent when no
messages are available (idle processing)).
Anyway, this is not the place for these discussions. :)
I still have to check in Win95, unfortunately, upto Sunday I seem to
be stuck with work (outside the office).

You still seem to have some work ahead of you. That rotation looks a lot
like what I got from my first attempts. In fact, I only got mine working
when I switched to using quaternions to describe the orientations of my
objects... but I digress. :)
I would suggest that you use a top (large moment of inertia on one axis,
a much smaller one on the other two) to test the rotation. If you can
make the top spin and precess stably by giving it a large initial angular
momentum on the axis with the large moment of inertia, and small
momentums on the other two, your code is probably working.

Thanks for the offer, that's kind of you. Unfortunately, I'm not using an
OOP language, so a class won't do me much good. I just need to set things up
through WM_PAINT, like it's supposed to be done :-)

Shucks, thought I had it until I let it run for awhile. Sometimes, it almost
stops, then suddenly whips around 180 degrees or so. I'll try the spinning top
idea and see what it does. Thanks a lot for your help Petri!

i'm calling dynmamic under time interruption to guarantee a real time

Be aware of re-entrence calling !
