Hi James :)

Well...I'm very happy to see that since when (years ago) I started talking about Moi as a "2D workflows" tool, I'm very happy to see that with the AWESOME Node Editor and with your wonderful job now Moi is becoming a very very powerful 2D editor. A very specialized one indeed.

Now, I think that what is still really missing, is an easy and friendly UX.

For example: I need to round the corners of a closed poly line using that particular N.E. script? Ok. All I have to do is to push a BUTTON in the UI or fire a key shortcut, and that's it.

Unfortunately at present, i have to 1) open the N.E. Editor, 2) Load a particular script 3) Select the proper objects 4) Run the script 5) Close the N.E. UI


It could be awesome if N.E. would be much more tightly integrated with Moi's environment.

But I guess that for this update only Max would put his hands on it :)

New Random Point Node

This point generator creates random points in 3D space. On the surface of an Ellipsoid. Or inside an ellipsoid.

Either X,Y, or Z values can be set to zero for a plane point area or a line of random points.

New Delaunay Node:

This node uses a modified delaunator javascript library from:
https://github.com/mapbox/delaunator

The output Lines is for a single line graphics
The Triangles output generates triangles that can be used for planar face surfaces.

Copy the delaunay.js and delaunator.js files to the directory:
C:\Users\<UserName>\AppData\Roaming\Moi\nodeeditor\nodes\extensions

I would like to thank James for helping out with testing and design recommendations.

Hi Marco,

I can add additional url parameters. It will not take a lot of time.
Something like this:
moi.ui.createDialog( 'moi://appdata/nodeeditor/index.html?file=c:\\ne\\node1.nod&step=1&close=1', 'resizeable,defaultWidth:1,defaultHeight:1', moi.ui.mainWindow )

Dither Node

This proposed node would take the output of "ImgSample" node and process the z values into a boolean (1s & 0s) stream , so that the density of 1s in sequence would range from lowest values to highest values. (ie black would be repetitions of 0s, and white would be repetitions of 1s, while greys would be patterned sequences of various combinations of 1s and 0s)

The result would be the conversion of a greyscale image to a series points on the canvas similar to the arrangement of pixels from a photoshop greyscale conversion to bitmap with diffusion dither.



Alternatively, the node could have pointAeeay input and output, extracting the z-values internally.

There are a number of resources online about dithering algorithms, eg: http://www.tannerhelland.com/4660/dithering-eleven-algorithms-source-code/

& of course Codetrain:

I have been dithering in photoShop then importing into "ImgSampler" node to achieve a similar result, but I would be great if this process could be done directly in NE, giving ultimate control on end result.

Have a great weekend

Some new works for the repository for the next week! ;)

Hello Max! Great to hear you again :)

That new feature could be very very useful!

Thanks a lot Max!

Waiting for this welcome update :)

Let us know when it's about to be released, thanks.

Ciao!

Hi Marco,

In nearest future (maybe next week), I will release a minor update. Few bugfixes and a couple of interface features. Nothing special.
Of course I'll add more url parameters, as you asked. I implemented this feature yesterday, everything works well, but I need some time to prepare the current wip version for release.

As I can see, everything goes as I planned. I made an engine core, community make nodes.
I will continue developing NE core. At the moment I try to find a best way to implement a Loop feature. I think it will be useful for fractal generating and many other things.

P.S. And yes, I'm waiting for v4 release :)

Thanks a lot Max for your kind reply :)
It's great to hear that you keep on working on this "magical" piece of code :)

Great news to hear that you did this new "url parameters"!

Yes, the community is doing a SUPER, SUPERB job in creating very powerful and "exotic" nodes!

Waiting for your next release with some UX enhancements (very needed now)


Ciao and thanks!

Hello James!

I write here a reply for your latest post on the "Current NODE EDITOR folder", because I don't know where I can write my thanks to you :)

@You: "...I will replace as new revisions are made to node editor and
as new extension nodes are added, so that the most
current NE folder can always be found here..."



Keep on doing this very good behavior :)

You know that this, is one of my most wanted "good behavior" in this community :)

P.S.

I've lost my actual latest version of the working N.E for the "old" version of Moi (v3)
Could you please provide that N.E. package also for the V3?

Thanks a lot again.

Ciao!

Hi James,
Could this be developed into a CIRCLE PACKING NODE?

@ James
Have you a web site different than Instagram because access is limited when visitor has no Instagram account!

Marco,

>> Could you please provide that N.E. package also for the V3? <<

I've always believed that NE was the same for both v3 & v4,
but if it doesn't work for you with v3, then perhaps not.

I have not used v3 for at least a couple of years,
& sorry, do not have a v3 version of NE to upload.

Pilou,

.>> Have you a web site different than Instagram because access is limited when visitor has no Instagram account! <<

Yes, I have a website: www.jameshargraves.com ,however doesn't show any examples of nodeEditor experimentation. As far as limitation on Instagram, IFAIK you don't need to be registered to view post. I only started using it because the swiping of multiple images seemed like a good way of showing node circuitry, which tend to extend horizontally.

Alex,

.>> Circle Packing <<

Yes I will add this as a node proposal. I first need to contemplate how it might best be implemented.

Thanks

@James
We can see the 36 last images with the Node Editor on Instagram before to be blocked! :)
Better than nothing! :)

As requested by Alex above http://moi3d.com/forum/index.php?webtag=MOI here is a new node proposal for the wishlist.

GeoPack Node

This proposed node would take a field of points and calculate radii of close packing circles at each point. These outputs would serve as inputs for "circle" node, or alternatively "polygon" node. Obviously shapes other than circles will not truly close pack, so a "scale" input is included to adjust sizing of individual elements. I have included a pointArray output, however it may be removed, as the point source output would serve similar function.

I have shown here the "GeoPack" node paired with "Dither" node (proposed earlier: http://moi3d.com/forum/index.php?webtag=MOI&msg=9581.122 ) to create an image based circle packing illustration.

I am fan of Daniel Shiffman (I have seen all its videos! ... Yes i am maybe a little addict... :D

Free Processing (Java) & now Javascript Online (P5*Js) are truelly amazing coding progs!
Processing speeds * 3 than P5*Js for critical projects...
Alas not yet free times for play with them! :(

my little one :) (Drag & Drop an PNG image with a transparent bakground - best if it's 1024* 512 maxi)

another little one :)

Thanks James thats great - is it possible to put a node in to control spacing between circles and maximum and minimum hole size this could be a very valuable tool in the creation of laser cut screens. Regards Alex. Here is a job I completed several years ago I used Grasshopper to achieve similar results.

Nice result! What was the material ? (Metal, wood, cement...)

Alex,

Just to be clear, my post for proposal of "geoPack" node, was just a proposal, not the contribution of a new node. That would be the task of someone more skilled in coding than I.

But to answer your question: the node for controlling min & max radii would be ArrayExt/reRange node (as it happens, this is one of the few nodes that I have actually contributed).

However to achieve a result similar to the images shown, with equi-spaced holes of various sizes, you would simply link you close-packed circle pattern to construct2/offset & apply the desired offset to each circle.

PS The screen looks great BTW.
What is this building? In Sydney? it's OK i found it
