JFR - Twirl Surface

Comment

Comment by Joaquim Filipe Reis on August 30, 2013 at 7:28pm

Thank you both, for bringing to us Kangaroo and Nudibranch, actually i have some ideas that I want to explore, however the problem is that i don´t know how to code and design a plug in , this is something that i want to learn and develope in a near future, because I feel that is something essential for explore the parametric approach to architecture. In relation to twirl attraction of Nudibranch, i preffer using [Twirl  GHUO] because it is more faster , however [Twirl] of Nudibranh it is better because we can use multiple attractors. This is my approach to Twirl surface using [Twirl GHUO].

Good to know that you used the GHUO that I made. The only difference of this user object and the twirl Attractor of Nudibranch (see attached figure) and Daniel's vortex (I am just speculating on the forces applied in this case) is that they are both iterative methods of calculating the particle's next step. Maybe I will add the possibility of these attractors working both as iterative and "linear" methods.

Good job!

Thanks for the pointers... I'm gonna try one later today

Thanks for the explanation Daniel, now I understand. You are right in 0.90014 version we don't have these additional outputs, and this is the reason why the error occurred.

I think it was after 0.9.0014 that the additional outputs on List Item got added:

It's a handy feature which I often use in Kangaroo definitions, but I don't think it's Kangaroo causing the error in this case :)

Sweet!!!  Nice work.

The version with which i am working is 0.9.0014 , and "item list" appears on " sets - list item". However for some reason when I use Kangaroo occour this error, probably I need to upgrade my grasshopper version, for sure.

If it is the 'list item' component that is unrecognised, then maybe due to an older version of GH ?

Hi, thanks for interest, actually I use Twirl GH User object for the first step, developed by Marius Tsiliakos. What I made is put the Twirl result curves running attraction to deform the inicial surface. It is a very simple approach, only with a two steps. Twirl for deforming curves and attraction for deforming surface. Later i will provide the information organized. A brief note to "swirl mesh " when I open the file occurs an error [ list item - unrecognized object ] and actually i don´t know why. This error occurs in others definition that contains kangaroo too.

Not sure if this is anything like how JFR did it, but here's a way of doing something similar with the Kangaroo vortex force:

(can't attach files to comments, so I uploaded the definition at the bottom of this page)
