3D Classes Demo, with Texture-Mapping
Yeehaw!
Thank you Mark, thank you Jiri!
I've actually grasped texture-mapping, and have incorporated
it (loosely) into my 3D classes. Right now, I've only got a
demo working, so it's really only meant to show the routines
off, not to be readable. It *should* be 2.0-compatible, but
don't sue me if it's not. (If you actually WANT this demo,
email me within an hour and--if you're lucky--I'll be around
to send it to you. Or, you can download it from:
http://www.geocities.com/~rodjackson/sphere.zip
provided I can post it to the site within an hour.)
The demo maps Mark's "grass" bitmap onto each facet of a sphere
made of 128 polygons, which is rotated and re-drawn several times
to give the appearance of animation. There's no backface-removal
being done yet, but it runs at a "decent" speed--on my Pentium II,
that is. I suggest at least a Pentium to run this (or you could
lower CIRCLE_RES to 8; it'll be a blockier sphere, but it'll run
faster.) It's affine texture-mapping, not perspective-correct, but
it works.
I should release new 3D classes soon that incorporate all of the
changes (including, hopefully, optional z-buffering) in a clean
fashion; I'll also include some much better documentation, and I
think the library will finally be comprehensive enough to actually
warrant a name.
Things are getting exciting! 
Rod Jackson
P.S. -- Some of you might notice that the demo is zipped with
Quartz v. 1.3; you haven't missed an update, I'm about to release
that pretty soon too...
