This month's Polytope of the Month is the runcinated snub 24-cell:

Nothing new here, but this is the last of the known scaliform polychora on my website, so it seems like a natural thing to follow after spidrox. Some of my favorite renders:

(showing the pyritohedral symmetry of the cupolae)

(showing the cells that lie on the projection envelope).

Actually, there's one more convex scaliform polytope you haven't posted yet - tutcup (truncated tetrahedral cupolipirsm), which has 2 truncated tetrahedra, 6 tetrahedra, and 8 triangular cupolae. It is a segmentotope whose bases are two oppositely oriented truncated tetrahedra.

Ooh! Thanks for the tip! I'll be sure to post that next month! :lol: :nod:

Are all of the convex scaliforms already known? Or are these only the currently-known ones?

Definitely yes in 4D. They are related to a specific convex uniform polychoron (ex. tutcup-sircope, bidex-ex, and prissi-prico).

Not sure I understand. Are you saying we know all of them, or these are the only ones we know of? If the former, do we have proof that there are no others?

Anyways, in the meantime, I've been adding the Johnson solids to my website, and today came to J32, which is an EKF of the icosahedron. So I made an animation of it:

I know you guys have been asking for this for a long time... :oops: well I finally got round to it. :nod:

Hmm, apparently I forgot to post this month's POM here:

Y'all probably can already guess what this is, so I leave it as an exercise for the reader. ;)

Ahh, how many months have gone by and I haven't posted the latest POMs. But here they are (click on image to visit the respective page):

July: Image

August: Image

September: Image

October: Image

I seem to keep forgetting to update this thread. Here are the latest renders:

November:

December:

January 2019:

I know, I know, sorry, been pretty busy lately so haven't been able to do much rendering work on the non-trivial CRFs, so I fell back to just picking interesting members among the segmentochora for rendering. Well, actually, not even interesting members necessarily, but just simple ones that I happen to have the model files handy for.

And my buffer has been exhausted since 2-3 months ago (that's why the last few POMs have been late), so I'm gonna hafta build up my Polytope of the Month buffer again. I've been wanting to render some of the more interesting CRFs that I still haven't gotten around to, but I haven't dared so far because of the pressure of needing to come up with next month's POM entry. (And I'm afraid to take a month off, because the last time I did that, that month lasted almost 4 years. :lol: :oops: :( ) So I gotta build up another buffer of relatively simple CRFs for the next couple o' months so that I can work on the more interesting ones.
