question on polygons

I wanted to thank everybody for all the TERRIFIC rotating polygons
that have appeared here over the last couple of days. They are
certainly well worth the effort, and I am happy that they are
included here in the files section of egroups.... [oh, I guess Dave
Keenan's aren't actually on THIS site, but it might be nice if he
could upload them to the "files" area.]

I have, unfortunately, a rather general question. Of all the
rotating demonstrations, I believe Paul Erlich's -- if they are
played
continuously in the Windows Media Player are among the most
instructive...

HOWEVER, I have always thought of our beloved "hexany" figure as a
two dimensional object. Is it ALWAYS a THREE-dimensional object, and
we are just not usually seeing all of it when it is portrayed on a
page -- you know, it usually looks like a big "star of David"...

OR is the rotating "3-D" version some kind of "special case" of the
CPS (??)

Thanks!

Joseph

Oh gee... I guess the 2-D and 3-D hexany pologons are actually
EXACTLY
THE SAME thing... it's just the way they are PROJECTED...

correct??

Right -- that's just one projection. And the dekany is 4-d, and the
eikosany is 5-d . . .
