Vortex Mesh

Hi guys, I have been developing some sketches where the start is performed through the grasshopper, but in the design process I introduce Zbrush and Blender. Anyway, once I lose the parametric relationship and malleability, I'm back into grasshopper to study one way to obtain the same result just using grasshopper, I attached one image and the file about the strategy that i´m study. If anyone here know a more effective way ,I really appreciate. Thanks in advance.

Well here you have plenty of room to play... I think if you want to create "movement" is best done iteratively, fractionally (here I use hoopsnake), rather than an algorithm with the movement parameterized. The logic here is to use geometry to form a direction vector to every point, and before applying the move, relate that direction with neighboring (ideally should be a vector field, but it is not the case), with the idea of harmonize directions. I use here the mean of the neighbors, but I would recommend using the Laplacian instead, to produce diffusion. I hope it helps you.

Edit* Ouch, I forget the ripples over ripples, but should be able to add it with a length associated with the distance to atractor geometry.

Thank You Daniel, pretty smart the idea of using Hoopsnake. Your point of view will help me for sure, i will keep pushing it, and at the end I let you know the result ! Once again, Thank you.

I put HoopSnake.gha in the Components' Folder where all other plug-ins for Grasshopper are. But, HoopSnake does not show on the tabs when I open Grasshopper. Also where should the remaining Hoopsnake folder in the archive reside?

TIA!

Hi Kim,

do you unblock the HoopSnake.gha [ right click - properties, unblock and apply ] in GH Library Components folder? - It Should appear at Ribbon, Extra.

Yikes! .....How silly of me to expect the names to coincide, Urrrrghhhh!

Regardless...I was hoping some geometry variants of the type Daniel posted above would be possible. All I get a Sphere with a small distortion in the surface geometry. Which does not even come close to the variants possible in your original Vortex script.

Also back to your original question: its possible to save the geometry to .STL

After which it can be imported into AD's (free) MeshMixer or further manipulation.

You just need to play around, to interpret how does it work. Get some time exploring this approach, actually the idea of Daniel to introduce Hoopsnake in the process it is really interesting. Follow the approach that I show in the video below. Now i´m trying to improve the self collision mesh. : https://vimeo.com/144273670

I saw your Torus video. I was actually interested in seeing if your type of Mesh Vortex manipulation could be applied to various Iso Surfaces other than just a Torus which by chance happens to be a Rhino surface. There are a number scripts that use VB or Fx script comp. that are capable of creating Iso Surfaces. Millipede happens to have a very good Iso Surface Comp. The Iso Surfaces Baked by Millipede are recognized in Rhino as a Closed Mesh.

My question: Do you see a Rhino Mesh component working, in your script, which would allow further Mesh Vortex manipulation?

oops! I think I just answered my own question :(

I don´t know if I understand you correctly, I don´t have doubts about "save geometry to .stl". Yes, you can work in any type of geometry that you want. I show in the image bellow a quick test made in a isosurface through millipede where i show the vortex effect, performed.

All is well, ....I was too hasty, with my slow computer. I had not noticed my Iso surface had not been absorbed into the Mesh comp. of your vortex effect

Great paradigm for how to generate beautiful geometry by thinking in meshes and local distortions, which is what commenter Daniel Abalde has been doing with his PhylloMachine plugin.

Thinking this way was also impressed upon me when Vincent Soler suddenly made a static octopus mesh wiggle its legs realistically:

Hi Nik, I saw post Vicent post, nice results. Sure it is always difficult to obtain a nice result mainly because of the mesh self colision. With the help of Daniel, i keep developing this strategy, and in the video bellow a present the result I got for now.
