generative modeling for Rhino

Trying to learn a bit about mathematical surfaces and how to build them in GH using the expression editor. This was a pretty interesting one I came across on the Internet of a form called an Umbilic Torus. It's like a Moebius Strip in that it only has one edge, but it is a 3D form.

This definition also puts to good use a method for creating tree data from a single list, a problem I had that I got some assistance on over on the old Google Group from David Rutten and others.

I just find that you attached the GH files, and I have got to know the answer to my question.
Thx all the same ~

And you can try the Srfgrid component instead of the last part to generate a better-looking surface.

Thanks for sharing~~

Excuse me, I just want to know when you got a set of parametric equations, how to get the model from the expressions? Is it Mesh or Nurbs?
Thanks so much!

interesting! there are so many possibilities with
Grasshopper:)


something back to the world
---------------------------------------------------------------
X(): sin((v/1)-(13*v)) +- 3*sin((u/.25)+v)
Y(): cos(u)*((11+cos((v/1)-(13*v))+(2*cos((u/.25)+v))-v)-v)
Z(): sin(u)*((11+cos((v/1)-(13*v))+(2*cos((u/.25)+v))-v)-v)
[u]:-pi, pi
[v]:-pi, pi
------------------------------------------------------------

Cordially
Torolf
