Thread Split: Some posts in this thread have been moved here

Hello,

I want to share a draft or better a proof of concept for some new nodes. They work not stable, has bad performance and are critical to their parameters. So don't try to use it for creating something serious. I am at the beginning to understand the problem in detail. It's something for a boring rainy sunday.

A nice weekend to all

Hi All,
I'm experimenting with animating a mechanism using the quartz node as the cycle actuator (time line).
Can anybody tell me how to have various start points for different movements .
As an example Quartz set to start at 0 and end at 250 how can I trip a start of a movement at 50 and stop at 200.
Any ideas
Barry

Hello Barry,

start Quartz from 0 to 150 and add 50 with a math node? I don't really know what You want to do.

Or something like that, if you want to connect different arrays with values?

Hi. Karsten,
I'm using the quartz node instead of a slider to give my selections movement but as they do not all start at 0.
Some start moving at 0 and others maybe stationary till say 50 then move.
So if you think of the quartz node as a time line and it triggers movements at given points.
I was thinking an if/else node might be my answer ie: if (condition) {  block of code to be executed if the condition is true}
else { block of code to be executed if the condition is false}
Hope this clarifies what I'm trying to achieve.
Cheers
Barry

Hello Barry,

have a closer look to the posted b.nod file or have a look to that one - you can do that with that;-) maybe you can also use the compare node.

Cheers

Hi Karsten,

formfinding node is very impressive. My dearest hope is that showers are forecast for tomorrow (your time) so that you may finesse the coding.At first, I had assumed that Moi was freezing when I tried you examples, but then when I finally saw the results, my heart leaped...truly truly inspiring stuff.
(I have dreamed the dreams of Frei Otto)

Great work!

I'm trying to build a nod using the circular array node.
It appears that the node requires the count input to be an integer.
Is it possible to convert the output of a Math node from floating point to integer?
I've tried using (Int) in the Math function field but that doesn't seem to work.
Is there another way?

Mike.

Hi Mike,

Use Basic/Math node with formula: "round(a)"
to round to near integer,

or floor(a) to round down
or ceil(a) to round up

Hope this helps
James

Thanks!!!

Hello James,

it will take a while until the node will work. At the moment I have some bugs and I'm not a programmer. JavaScript isn't easy to debug. I have to find a solution for fast convergence and a good criterium for equilibrium. Sometimes the algorythm blows the mesh into space. A display after every step won't work, but I don't know why - it would help to understand what's going on - and would be an eye catcher. I don't want to ask the experts, because they have better things to do (v4, Elephants, additional interfaces ...). What to give to the output and which format is also not definded - at the end we want to do something with the result.

So - the winter comes here and that will help to focus to such things.

Have a nice day

Hello Barry,

here is another example that demostrates the workflow. If it isn't useful for you you can maybe relax with it.

Have a nice day

Hi Karsten,
thanks it is relaxing however the node workings are beyond me.
I have tried to create an if/else node but it does not output when it reaches 100.
Could you have a look please if only for your entertainment.
I did try to enter it within the formula section in the maths node but no go.
As they say a little knowledge is dangerous thing.
Again many thanks
Barry

Hello Barry,

to understand the nodefile it is neccesary to think in positions of your objects. Then select the matching positions of your objects with the idxSelect nodes -controlled with the Quartz node.
Thats all.

I will have a look to your idea and try to understand it, but not today, it's late in the evening and I had some beer while watching TV(Soccer - Worldchampionship qualifing:-).

So have a nice evening
Karsten

Hello Barry,

you don't Need a new node for that - have a look to the example. Compare and split will do that what you want. Have also a look to the RMB on split.

Have a nice day

Hi Karsten,
thanks will experiment with it.
Just out of interest could you explain why when using my if/else node it did not work when value of 'a' was 100 or over.
It's set to if (a>b) {out = (a-b)} else {out = 0}
I know it's my coding and inexperience but it will help my learning curve.
Many thanks
Barry

Hello Barry,

your variables a and b are Arrays! If you want to compare elements of the arrays you have to Access the single elements with e.g. a[5]<b[0].

What the result of a<b is? I don't know. The this.properties.mode things are only useful for the multiprocess functionality Max implemented.

I think you have to implement a multiprocess function (Standard Long) or do it manually when you only want to compare all elements of the "a" Array with one single value of "b" (b[0].

for (var i=0; i<a.length;i++) if(a[i]<b[0]) doSomething();

I hope that helps for further steps.

Have a nice day
Karsten

p.s.: out is also an Array - so use out.push(a[0]-b[0]);-)

Hello Friends
Continuing exploring Minimal Surfaces,
in particular of the Scherk Singly Periodic
and the possibility of aggregating of the base module,
particularly in the most popular Saddle Tower,
I would like to share with you this interesting one
transformation...
a Twisted Torus of the Basic Saddle (Low Poly)
with the possibility of increasing the branches of the tower itself.....
file at this link:
http://www.mediafire.com/file/sf3u5jrbc9dc5jc/Twisted_Scherk_witn_n%C3%82%C2%B0_branch.rar
Good depth.......
Have a nice evening to all

Hi AL!

I have a problem with all the nodes that you have posted lately.

None of them work with the latest 0.97.... version of NE.

Every time I load one of your node file, the "Run" button of NE is always disabled.

Instead if, for example, I create a new node or load one of the latest Max's node (Macro.nod for example) all works fine.

Please check this screencapture, it is relative to the node you posted at http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.603



Maybe I'm missing something...

This is the content of my "C:\Program Files (x86)\MoI 3.0\ui\nodeeditor.v.0.97.2017.10.05\nodes\extensions"
and "C:\Program Files (x86)\MoI 3.0\ui\nodeeditor.v.0.97.2017.10.05\nodes\extensions\libs" folders





And this is the code I have into index.html file of NE :

loadScripts('core','lang, compatibility, colors, geometry, main, editor');
loadScripts('nodes','macros, basic, logic, points, curves, solids, construct, transform, objects, interface');
loadScripts('nodes/extensions/libs','*');
loadScripts('nodes/extensions','*');
loadScripts('core','init, ext.*');

Could you help me ?

Thanks.

Ciao!

Hi Marco
the file posted,I did it with 0.96 Version....
I downloaded Version 0.97, but I'm not using it yet
ciao
