Hi Psygorn,
After much looking, rectangle2 node was located here:

http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1710

There are 4 "new" nodes in file >>>>>>>>>>>>>>"shapes.zip".<<<<<<<<<<<<<<<
(Wayne's shape nodes???)
Unzip the file, and copy the 4 .js files to your %AppData% folder.
For Windows 10, ...AppData\Roaming\nodeeditor\nodes\extensions.

I am so rusty at nodeeditor, it may be that these 4 nodes are not yet integrated into nodeeditor menus. Not sure.
They are coded to hook themselves into the Curves2 menu...
(Circle2, Star2, Polygon2, and Rectangle2)

Hello Brian,

Thank you for your reply, I found those nodes u mentioned. however, I did not find idSelect! and I did not achieve the same results as James did!

Here is what James has achieved: https://www.instagram.com/p/CK8Qb6XsHOa/

and I have attached the Node file to this reply, please take a look at it. ( I know you are rusty but I believe you might be able to help me to recreate what James had recreated)

Hi Psygorn.
Something like this.

Hi WN,

Yes! u are a wizard!

Thank you!

:-)

(Gods of nodeEditor heard my call :-)

By the way, I have a question,

In James Instagram post, it seems the generated mesh does not have a seem line, is it because it is rendered? or is it because of his node?

Psygorn,



Yes the .nod file generated a seamless mesh.
Unfortunately I long ago deleted the original file,
but I will rebuild and post over the weekend.

Thank you James :-)

And I wonder could that pattern be applied to a torus?

And how can I get a decent understanding of nodes? from where should I start? to me it looks like dark magic! :-)

Since a torus is a rectangle plane that is rolled up, then curled around, it should be easy to make up a voronoi torus. See previous hex patterns on torus, nodes.

<< from where should I start?

Make very small ones, reload yet made, and training 26 h / 24 h ! :)
And of course https://moiscript.weebly.com/biblio-elephant.html
Bon courage!

PS It's more easy to use a Node(s) than create it!
This one by r2d3 is a true gem: you can animate anything along any path! :)

Psygorn,

As Brian says it is easy to flow a pattern to torus since it homologous to a rectangle.
The trick however to make the voronoi pattern seamless over the surface, is to repeat
the random point field offset in both dimensions, generating the pattern and intersecting with
the original frame prior to applying flow.

.nod file attached.

Thank you James,

Hi James,
I'm only getting half the torus with a voronoi pattern ?
Also I noticed that the inputs to the randompts node does not update in the panel in the nodeditor but does update the drawing.
Perhaps its my version of the nodeditor.
Anyway thanks for posting have a good Xmas.
Cheers
Barry

Hi Barry-H,

I noticed that too but I think with a little bit of tweaking u can have a torus voronoi-ed all over :-)

I have to confess I don't know about the nodes or how they work at the moment! I just hope this could be helpful.

Possibly James could provide a deeper explanation :-)

Hi Drillbit,
yes I had got a result also by tweaking the rectangle sizes.
Cheers

Barry / Psygorn,

I am unable to repeat the pattern on half issue that you have experienced.
Nevertheless I made a small change to NOD file scaling original rectangle
rather than generating a 2nd rectangle, though it is unlikely that this is the problem.

What is more likely is that the issue is copying of point field into 4 quadrants
prior to generating the voronoi pattern. This should be possible to do with a
single "MovePts" node but it fails to work, necessitating the use of 2 such nodes in series.

It would appear that this 2nd move (copying) is not registering for you.
I am not sure if the reason I have not experienced the same problem is due to the fact
that I am using beta version for Mac M1 processor.

There is one more thing I could try: converting points to point object and then copying them
into quadrants before reconverting back to point field. I imagine that this would radically
increase the computation load since new geometry would be generated with each "MovePts"
operation.

But first let me know if problem persists with this new NOD file

Have a great weekend

Thank you James.

For what it is worth, my computer is still generating half of the torus with unperforated inner and outer skins.

Thank you James,

However, as bemfarmer mentioned the issue still exists!

Hello James,

I tried to recreate one of your works.

you can see it here: https://www.instagram.com/p/CCo6mQUJxkN/

But I ran into that problem.

you can see the Error here: https://moi3d.com/forum/index.php?webtag=MOI&msg=9581.240

Psygorn,

Try this version.
I have repeated original point field via math operation to x & y data.

It works for me...but then again so did my last NOD file.
I have been unable to reproduce the error that everyone else seems to have.
