algorithmic modeling for Rhino
Laurent, thank you so much. I can only wish I had your level of competence.
Given how advanced this already is, I feel a bit silly to ask for more, but I get the impression you enjoy the Grasshopper challenge, so here goes. Indeed, I would need the possibility to apply the curve to different parent objects other than a sphere, for example a cone, ellipsoid, or otherwise revolved surface, as you mentioned.
Ideally, I could modify the object on the fly in GH (or Rhino) and have the curve update accordingly. Lastly, I would need variable control over how close the rings are apart from one another both in their offset distance (top view) and z value. I was thinking perhaps this is possible using paneling tools attractors?
In any case, thank you for the amazing work.
I think there is a, partial, solution to your problem. For Spiral I did that
there is no equations (in my memory :-), the revolution shape is done with a GH component it is the same for the control over how close the rings. It is no more a loxodrome (constant angle on a surface). But as you will see it was not to difficult to design the London Swiss Re-tower.
That is very interesting. So much fun to play around with the parameters. I'll use it to train myself, thank you.
Thanks Laurent. Such a beautiful curve and a welcome surprise to get my hands on your description many years later for my current needs.. What a great community!
Happy you find it useful. This old forum is still a great source of definitions.
Happy end of the year.
