James you're becoming a "true master" of this kind of "mathematical art"!

Congrats!

In this period of my life honestly this is not a CG topic that's so much interesting to me, but I want to tell you that your contribution to this particular area of Moi, the NodeEditor, is really amazing!
I think it's (almost) on the same level of what Max did with all his amazing scripts.

Thanks for your passion!

I can sign Marco's words!

Respect!

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

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.
James

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
