Information

Nudibranch

Nudibranch is a set of components facilitating and automating Grasshopper’s capacity to generate distance-based value datasets, while recording particle traces moving within attractor defined vector-fields, that can be further implemented into animated simulations.

In particular, Nudibranch aims to automate the attractor generation and development process (one or multiple), while covering most of the frequently used cases, without however intenting to replace or render useless the basic understanding of how attractors operate. In addition a few animation components enable the real-time interaction between attractors and the affected data offering a more coherent output of the affected enitities or values.

Nudibranch is an experimental project and it might still contain  bugs. Please use it "as is", it does not come with warranties. Please give credit where credit is due according to the license file.

What is a Nudibranch????????? Specifically Glaucus Atlanticus..

You can download Nudibranch from the  Food4Rhino website.

A brief documentation and generic examples are also included in the download folder.

If you develop an interesting design using this tool, or even better if you want to share some feedback and your thoughts on Nudibranch just drop a line. It will be really appreciated.

Ty Ewa,

I have re-written most of the code and the components run significantly faster now. Hopefully there will be an update in the following months.

Best,

M.

Marvelous plug-in, thank you Marios:)

@Ivan

Thanks for your kind words.

Range is variable if you connect more sliders to the range input. I'm afraid that force and iterations are global for the moment. It would make calculation time really slow if I made those locally defined. But I will keep an open mind about that.

A simple workarround for the time being is to connect more twirl attractors to your definition and add the resulting vectors. You will get the result you are looking for.

Best,

M.

Hi Marios,
Just downloaded your tool, that's really great!
I have a question about the Twirl Arrtactor: is it possible there to control range, force and iterations for each point?

Hello Igor,
Thank you for your feedback.
I found the bug in the satellite component. (it isn't that it doesn't work with one item, it seems that its missing certain data types like GH_box. so if you reference a box from rhino(1 single item) it works, if you input a mesh from gh it works (ie mesh_plane) but if you input a single box, or sphere or cone it doesn't). Thanks for pointing that out. Will be fixed in the new release 002.
For the min/max value:
The meaning of a minimum value is that every point outside the attractor's range gets the minimum vector value (i.e 0.00 or bigger), so when the attractor is far away from the grid and the points are outside of the range of the attractor, there is no min value (is null)thus no vector to be added (so the points disappear).
in the case of the max set to true he maximum value of all the points within the attractor's range is being added to all the points outside the attractors range so there are no null points a valueis constantly added. However in this case it would be useful to set a conditional in the code so whenever the points are all outside the attractor's range the maintain their original coordinates. so thanks once again for pointing this out..

Best,
M.

Hi Marios,

thanks for great tool. But....

Could you explain the logic of a attractor range?

In my example when points out of attr range and cheked Max it's allright(more or less), but when cheked Min all values are crashed.

And why Sattelite component dont working with one geometry?

Humm Marios Thanks For your invitation, i will going to test it  congrats cuz looks interesting

Hey Marios. Just downloaded your tools. The Attractor tools have very convenient length and vector outputs so that it can be used to easily create scalar and vector fields. 

Grasshopper has so many plugins now... the snowball keeps getting bigger and bigger!
