Testimonials about Great Stella and Stella4D
- Mike Bedford, PC Plus magazine,
Issue 271, August 2008, p46-47
- "If you're unfamiliar with three-dimensional polyhedra, Great Stella gives
you the chance to get acquainted – in the on- and off-screen worlds"
- "You'll find that you can use the software with barely a glance at the
manual, but that would mean only using a small proportion of Great Stella's
features. This is quite a sophisticated program for those who want to go beyond
Fr. Magnus Wenninger (author of "Polyhedron Models", "Dual Models" and
- "I want everyone to know right off the bat that I am finding Great
Stella the greatest program ever devised for the use of polyhedron model
makers... What amazes me most is seeing the speed with which any one of the 75
uniform polyhedra and any of their duals can be instantaneously brought on
screen using Great Stella... The ease with which I can zoom in and out and
move all around in the Stellation Diagram is fantastic, then to view the Base
Stellation immediately as well is something I have to call miraculous, i.e.,
wonderful... Finally the nets - wow! I can print them out to any size I want"
- Edward Popko (author of
Divided Spheres: Geodesics and the
Orderly Subdivision of the Sphere)
- "For the pittance you charge for Stella, every person on earth that
has ever looked at a geometric solid should have this program."
- "I spent a couple of days with Magnus Wenninger and he is your best
marketing agent. His skill with Stella is truly impressive. I was ashamed to
tell him I was back a level. Knowing that I work in computer aided design, he
asked me what impressed me most about Stella. I told him the core elegance is
in the data structure. So many byproducts come from it: veiws, nets, cell maps,
etc etc. I have take my hat off to the cook... This program is a steal for
what you get. Every college kid in math with a PC ought to have it. It is
- Charles Fleischer (the voice of Roger Rabbit!)
- "You are a genius... I will tell everyone about yer work. It is the
best of all the polyhedron engines"
- Ian Douglas
- "I love playing around with all of the beautiful objects you include
in your library - and as a game developer, mathematician, and web
developer/designer I feel like I can speak from a position of authority when
telling you that your UI/UX experience is AMAZING and intuitive. I hope I can
one day make something as easy to use as your software :-)"
- Steven Bader
- "I am absolutely blown away by this program. I have been on it 10
hours a day since I purchased it 3 months ago."
- N. J. Pinney
- "Appears like a work of unadulterated genius"
- Mark Ellis
- "Utterly brilliant software... I have never used such brilliant and
well written mathematical software as this, and I really can't praise it
highly enough. I dug out my old copy of Coxeter's Regular Polytopes and it
all makes a lot more sense!"
- Robert Alan Asistent
- "Beyond extraordinary! Thank you so much for this stroke of genius.
Bucky left his body too soon, he would have loved Stella with a passion."
- George Olshevsky, on Great Stella
- "Nothing prepared me for the aesthetic experience of seeing hundreds of
complicated facetings and blends, rotating in space in real time, and in
stereo, essentially at a few touches of a mouse button, practically without
having to lift a finger to actually draw or build them. This really brings home
the notion that the uniform polyhedra are just little islands, which just
happen to have all their edges the same length, in a vast ocean of isogonal
- "Great Stella makes assembling nets of convex regular and uniform polychora
almost child's play."
- "Constructing snid and grid facetings with Great Stella is like
eating Lay's potato chips--you can't stop with just one."
- "Great Stella is a wonderful system and really should be on every
polyhedron model-builder's computer."
- George Olshevsky, on Stella4D
- "Let me tell you, it's a blast. Nobody who's interested in
four-dimensional figures should be without this software! If you really want to
get a feel for what symmetric polychora - particularly the uniform
polychora - look like and how to work with them, this system is the state of
the art. Stella4D is - to employ a much overused but nevertheless appropriate
cliche - a programming tour de force...
Sectioning - Here is where Stella4D really shines. Back in the 1960s I could
only dream about having an interactive system for viewing polychora sections
in real time, in full color, with hidden faces removed. And here it finally
There is no sequence of still pictures that can convey the aesthetic
experience of watching the changing sections of a polychoron of interest as it
"passes through" our three-space, an experience that only modern computers can
provide. I find it amazing that my computer is fast enough to perform the
calculations to make a movie out of the sections of an intricate polychoron.
When I made movies of the six convex regular polychora back in 1972, the
120-cell and 600-cell movies took nearly an hour of IBM 7094 computer time
Sections in Stella4D are calculated in real time, and you can set them
running perpetually using mouse inertia, bouncing from one extreme to the
other. You can change the sectioning direction in midstream, and the "movie"
just keeps running. You can also set the section tumbling as it's passing
through, and/or view it in stereo. This is real luxury compared with what was
available when I wrote my MSc thesis on computer polychora sectioning.
...I haven't had so much fun with a software package in years."
- Jonathan Bowers (discoverer of the majority of nonconvex uniform
- "When I first started exploring polychora back in 1990, all I had was a
pen and some paper - and therefore the best graphics I could play with were
some hand drawn vertex figures and some sections of the simpler ones. Now only
18 years later, we have Stella4D - which can view all known uniform polychora
(as well as many scaliforms and compounds and their duals!) as though a 4D
being tossed the actual objects into our 3-D universe spinning and bobbing up
and down as we see the sections in real time (although you may need more
graphics power to handle the more complex ones) - its pure awesomeness - we can
even use it to go inside hollow polychora to see their ever changing cavernous
views - and to top it off, we can put on our 3-D glasses with the stereoviews
and reach out and nearly grab the polytopes - this software is a must for any
polychoronist! - I can't wait to see whats next for future installments of
- Paul Strike
- "Great Stella installed perfectly. Having spent a couple of hours
playing, I would like to thank you for a brilliant bit of software. I know
nothing about this facet of geometry (I am a statistician... simply attracted
to pattern in any shape or form), but your program is endlessly surprising...
something around every corner, and so many corners! My best (self-indulgent)
purchase in years."
- John Vik
- "Thank you so much for the creation of your Stella Polyhedron Program.
I've already spent countless hours of pleasure exploring and manipulating
- Yvonne Banks
- "Just a short message to say what an excellent package I think it is.
I am very much enjoying using it - its in danger of becoming a bit of an
- Brian Vale
"Thankyou for your excellent Software. I have been looking for something like
it for a long time! ... You are a legend!"
- Karl Horton
- "Thankyou for enriching the world with Stella."
- Stephen Rhodes
"I thought it was about time I dropped you a note and thanked you for a
brilliant program. I used to build models the "hard" way, working out the nets,
drawing a template etc, then by chance I came across your web page. I liked the
look of the program very much, but felt it was quite expensive - for my pocket
anyway. Eventually I gave in to temptation and purchased what was then version
1, and I loved it, upgrading to version 2 as soon as it became available. Now,
having used it, I take back my thoughts about the program being expensive; it's
been worth every penny."
- Leigh Christopher
- "The models in this program are truly awe inspiring. Watching them
rotate and morph makes me feel I'm getting a glimpse of another dimension.
Great Stella is the perfect tool for discovering some of the most beautiful
hidden jewels tucked in an intricately mathematical part of reality. The
program is a joy to use and runs extremely smoothly. I look forward to building
models from the printed nets. I just love it! Thanks."
"Stella is Rob Webb's astoundingly comprehensive polyhedron exploration
application. Starting with an exhaustive list of polyhedra (including some I'd
never heard of), he provides a mind-boggling array of operations to perform:
dual, stellate, facet, augment. All aspects of the operations can be adjusted,
then nets printed out to make models. If you have the time and the inclination,
Stella provides an endless set of rabbit holes to explore."
- Richard Stratton
- "After using your program for the last couple of days, I am truly
amazed what can be produced."
- Francis Jones
- "I just wanted to say that I continue to be amazed at Great Stella -
- Burt Clawson
- "The best program I've ever seen for exploring polyedra.
Recommended!... This program is fantastic! I thought I knew quite a lot about
polyhedra, and I've never even seen any of the 'drilled' polyhedra. I also like
the way you can explore duality through all the different manners, truncation,
etc... Great program!"
- Jim McNeill
- "I was printing off some nets last night ... I was extremely
impressed with that section of Stella (which I hadn't used before). That's a
fantastic piece of software you've put together."
- Ulrich Mikloweit
- "I'm VERY PLEASED about the functions of the great stella program
version. Indeed, it will be much easier for me to construct the most complex
- Mark Balaam
- "fantastic program! I am overwhelmed by the sheer number of
stellations that exist"
