Any idea about how this is modelled?

Hi

This is a known form made by Bathsheba the american digital artist. it’s a lamp
I am not sure if it was made in Rhino or SubD or
2022-03-11_13-25-02
a mix

It is a pair of dodeca hedrons the one inside the other. If anyone knows a recipe to model it I would be gratefull

Regards,

Hmm… maybe:

I had a go and think I got pretty close:

Still needs a bit of tweaking on the width and angle of the arms though.
I’ll share the definition later.

Maybe, if you’re lucky, @Bathsheba will share how it was originally created? :grinning: I seem to recall that model pre-dating Sub-d (at least in Rhino), but I might be wrong :grimacing:

Definitely from long before Subd (and Grasshopper).
Her page here says 2005

Yes, my folder for it is dated 2004. I modeled the topology in Rhino, conditioned the mesh in Surface Evolver, and did the texture by writing command-line utilities in (are you ready?) Perl. If memory serves, putting the rims on was the fiddliest part.

It’s not difficult to imitate, especially now. My favorite take is at http://www.bugman123.com/Math/index.html#Homotopy . Those little animations explain the topology really well, and don’t miss the vertical image at left of a similar design on a hyperbolic ribbon – I liked that so much, I borrowed it back. :wink:

Paul Nylander animations are good start. Here is my grasshopper animation of base shape.

It can be also done in wings3d or topmod.
