Hi Marco,

I have been buoyed by your kind words, although I don't
believe I am deserving of comparison with Max on any level.
Nevertheless, I'm greatly appreciative of your encouragement.

Thank you (& Mik)
James

You're welcome James! I think that you deserve due recognition :)

Ciao!

Hello Friends
An exploration, I think quite interesting,
of a fascinating and particular surface in my opinion, Dupin Cyclide Ring -
how many interested people find the file at this link:

Good depth to everyone
Have a nice day to all

a Macro that I think can be useful ..
at least I hope..

Hi Al et al,

That's very cool. I was impressed by door mechanism video on dezeen: https://www.dezeen.com/2014/02/11/door-reinvented-with-folding-mechanism-by-klemens-torggler/
but even better to see it animated in NE. Great work.


Maybe you can help me with a problem.
I have been trying to get my head around voronoi tessellation.
(I recognise that this may be a redundant exercise if/when Max converts his script to a node)

I have started with a mesh of triangles*, applied planar, extracted edges,
getStframe, generate 3ptCircle and find centers with BoundingBox node.

Now it is a matter of drawing lines between centers.
This involves incrementally taking pointDist for each point with the rest
and drawing the shortest (extract Min - compare - split),
then repeating for new minimum distance (2nd shortest) & again for 3rd shortest.

I have not included the nod file because frankly it is not even close to working as I desire.
Perhaps this is beyond NE as is, but I thought you or someone else might have an idea of how to proceed.

James

*Ideally, what I want to do is input a field of points and apply a Delaunay triangulation as my starting point;
though if that was possible, the same code could probably achieve voronoi meshing as well.

Very cool door!

Hello James
Many Thank you for your appreciation .... -

About Voronoi, I also tried to do something,
but I did not go further than you ...
My problem is that I can not sort with a logic (that is
very special), the points obtained as centers of the Circles
circumscribed to the source triangles, to obtain the ngon poly ...
I saw on the web the creation of the progressive field using
Lloyd's algorithm ... I have to say real poetry, almost magic
but all of this higher mathematica ..... unfortunately very far from my level-
I hope that Max or Karsten can soon give us this Node
Have a nice evening

This Delaunay and Voronoi stuff could be interesting in the future imho,
in case you could process also images with that in MoI, based on a point
set.

I played today with some old tools on my Mac and came up with the
idea to laser cut those Delaunay / Voronoi Designs, because i have
found a service which is imho pretty cheap and has lot's of materials
to choose from.

Hi All,

I deleted my last post because I was getting sidetracked, & the solution was much more obvious.
It is to find circumCircle centre and draw lines to midPts of triangle edges like so.



I will do some further development of this approach, but I think I'm on the right track.

Hi James
I think it's the right method ...
divide the sides of each triangle in the middle, join the center
with these points ...(so far I have arrived here too)
but,what is the final method to obtain distinct poly ngon ?
for me this is the obstacle to overcome

Hi Al (and others),

I have attached nod file for generating voronoi pattern from field of tessellated triangles (also attached).
This turned out to be far less complicated than originally thought. The real problem to solve now is converting
a field of points to delaunay triangulation.
