Mantis v0.3 (Mathematica Equation-Fractal tree-Nearest Value-Shortest Tour-Polyhedra-CA)

There are 2Main tools of Mantis v0.3:
1-Mantis_Cellular Automata

*5 Components for generating cellular automata 1d & 2d & 1d Totalistic 3colors + Find the nearest rule in Elementary CA for a list as shown in the image pattern example,and There are 1 component for generate & preview the 1dCA rules.

2-Mantis_Geometry

A) Mantis_Mathematica Equation which enable writing equations as Mathematica technique and get the result as a string
and for using this tool, don't write any equations which has an image result.

B) Mantis_Fractal tree which generate a self similarity branches which can be used as a line-length as a numeric order (for example as fibonacci)(iF you saw an error click on don,t show me this massege again"don,t worry)

C) Mantis_Nearest Value which gives the list of elements(strings or numbers) to which a value is nearest

D) Mantis_Shortest Tour, attempts to find an ordering of points that minimizes the total distance on a tour that visits all of these points once

E) 2 Components for creating 3d Polyhedra objects + Unfolding these objects into planar surfaces.

you can find it in the download section

Good morning, I am currently working with a mathematica model. I would like to transpose this equation on to grasshopper. I tried to do it with the strings... without success. Could you possibly help me ?

you cant send a command that will return an image. Mantis is calling the mathkernel.

so you can replace the parametric plot with Table

Would you have any .gh do help me start because it is fairly complicated to figure out which grasshopper component I am suppose to use. I read the tutorial provided with the install. I get the principle but It doesn't work with what I tried. Thank you for your help.

Here is what I started. Thank you for your help

Does Mathematica have to be open ?

Now it is working, I have replaced the wolframlink.dll into the component grasshopper folder.

However there is now a problem on the geometry itself. A part is missing in the surface. eventhough, the equation in mathematica is giving the right surface.

Could you help me solve that remaining issue.

thank you so much

you have to duplicate the first tree of points and put it again in the last tree and then connect it to the polyline then the loft

or copy the first line at the end of the list with a flip direction

Thank you it does work. However the surface as such is dicrete. I would like to work with the U and V parameter of the surface to work with the domain.

I have figured how to export mathematica.stl into rhino. It does work fine however the discretization make all the faces of the surface different from each other.

With the U and V parameter I can divide the surface into equal faces and I think it will be more convenient to have this. Do you have any ideas on how to achieve that ? Does the question make any sens for you ? thank you very much.
