There is a great chance that everybody here knows already the program
GreatStella for presenting 3D
polyhedra. One of the marvelous possibilities is the "crossed eyes
view". This gives you a beautifull 3D effect with unharmed colors even
for animation and you need no glasses or other equipement. This 3D
pictures have also a better resolution (sharpness). The effort for the
program is not so big because there must only be added a slightly turned
copy of the picture. MC4D is so convincing because of his beautifull
animation (especially when slow). This can be seriously enhanced with
little effort. Here
g> is an example without animation of course and having suffered from
screencapture and from sending by e-mail. Everybody knows how to handle
crossed eyes view?

I have taken a look on all your stereo photographs.
Awsome pictures.
My favorites: the white rose, the clouds and the mars visite.

Kind regards
Ed

Hello Edward,

Welcome to the group! It's great to see your interesting and enthusiastic=
messages. I encourage you to introduce yourself and tell us about your lif=
e, work, hobbies and your experience of solving the 4D cube.

About GreatStella, yes I've been well aware of it starting in 1999 but I =
doubt that many others on the list know about it. That was when Robert Webb=
and I were both on a polyhedral mailing list hosted by Magnus Wenninger. I=
t was that list that helped him to define the feature set and I particularl=
y liked his stereo modes. That list was understandably more interested stel=
lations than I was though I see from the description of the current version=
that he now has a 4D version which could make it a very good tool for 4D p=
uzzle makers. He also supports an "augment" feature in his 3D version that =
could be very helpful as well.

I'm a huge fan of cross-eyed stereo and have lots of stereo photographs o=
n my site. For that I use an applet that lets the user select from a long l=
ist of possible viewing modes. I always prefer cross-eyed viewing myself, a=
nd during my last programming work on MC4D I did implement a cross-eyed ste=
reo feature because I believe that it is very valuable for 3D work like thi=
s, but I backed it out in the end because I wasn't able to get it perfect i=
n the time that I was willing to spend on it then. You are right that the a=
nimations give a strong sense of 3D. The real value of a stereo mode will b=
e it's ability to let the user keep the full sense of the 3D projection whe=
n it is not in motion which is most of the time. We still have the change s=
et to work from whenever I or someone else next get the urge to work on it.=
This is listed as issue #35 in our Google Code issues list and it is my hi=
ghest priority item. I encourage you to see what else is on our list and to=
comment on them, star your favorite items, and add new bug and feature req=
uests.

Again, welcome to the list, Edward,
-Melinda
