Curve node may be used instead of polyline.
- Brian

---

Hello Karsten,

Thank you for your help, it works perfectly.

To use the curve segments as discreet sweep rails,
it was necessary to alter your Construct2/Sweep node
changing processInOut to "Long" as shown below.

Nodes/Extensions/contruct2.js LINE 62
var data = this.processInOut("Long", this.multiProcess, null, null);

Will this adversely effect its functionality?




Hi Brian,
<<Curve node may be used instead of polyline.>>

Yes, polyline was only a stand in for the purpose of clarity.
Also, Points/InterpPts node before curve node gives a more pleasing result at thread ends.

Keep on Noding

Hello James,

Yes it will effect the functionality. The node is able to process also 2 or more profiles and 1 or 2 Rails. It seems that the sweep factory uses some internal autoplacement? to distribute the profile to the rail, if this change is working for you (Just a guess - would need more details). I tried to avoid this . To distribute the profile you can use something like that:



I've chosen this way to make it possible to place also individual profiles to each rail. I don't know if this way is the right one.

Have a nice day
Karsten

Hello Karsten,

Yeah, I had realised that it was not necessary to alter your sweep node;
but rather just use "Long" MODE on Max's original sweep node.
I've restored your node to "Short"

Also, it's not necessary to use getCurveSFrame, if sweep profile is remote from rails.
Please find nod file attached.

Now I need to index perpendicular threads.

Thanks for your help.

Yep! That's right! It's early in the morning here;-)

Hello All,

Weave in both direction and wrapped over curved surface
(nod file attached)

Works with most up-to-date mod which can be found here:

Keep on Noding

James, you have written an interesting node!

I'll note that it took well over a minute to work on my Windows7 computer.
The result was 15508 kb.

(Reducing warp to 9 and weft to 13 ran faster, but with less detail in the result.)

Hi All MOI NODE-STERS

It would be great if some of the NODE developers could perhaps start a YOUTUBE channel taking beginners through the process of this tool set seems lots of development has gone in its functions expanding but little or no documentation other than forum drilling.

Could be a good new audience.

great to see the development.

Hi Brian,

Your point is well taken...so I have replaced weaveWrap.nod in my earlier post
with new version: WARP=13 & WEFT=19, as well as changing profile to hexagon.
This has greatly accelerated drawing to screen.

If fine mesh detail is desired, it is best to STOP the node running, change the inputs
and then press RUN.

You also reminded me that I should have mentioned that the WARP & WEFT input
need to be odd numbers to weave properly.

Thank you
James

Hi,
I'm trying to create my own node but having studied existing maths node
still cannot get the input values into the formula I want to perform.(I am a novice )
Attached is my pathetic attempt any advice much appreciated.

Hi,
got a bit further now have the inputs and formula working and giving an output
but the output is not working with the move node ?
HELP

Hi Barry,
I'm too much a novice to help now, but will study on it after work.
You must be close.
It is nice to modify something that already works...

- Brian

Hi Brian,
yes please have a look.
When I checked the outputs of N,P1,P2 i'm not getting any value.
So the formula's are not working and I can't find something similar to work to.
Anyway it's a challenge to learn more.
Thanks
Barry

Hello Barry,
starting with node programming isn't easy, but you have started it already - congratulation and welcome to the world of nodes. The problems in your file, is that your variables (inputs are numarrays) missing the element indexing - Always keep in mind that you are working with arrays!!!. To access the first element you have to use xxx[0]. Have a look in the attached file. The arrays are the requirement for multiprocessing data, even if they were not needed in this case. the same goes for the output.

Have a nice day
Karsten

p.s.: The variable R isn't used in your formula - If you use netbeans for programming or something similar, such things will be highlighted.

With Karstens change to varHelix, the bottle will move along x
(I renamed selected to bottle...)

I guess you are trying to move the bottle along x, to match the rotation of the helix?

Or are you trying to move the bottle around the helix?

To form the helix curve, it needs x,y,z points feeding interpcurve...
I guess you could output dx, dy, and dz to the move node...

- Brian, confused

Hi Karsten,
thanks I would not have found the answer without your help.
There was still a problem with the variable P1 formula which just needed
an extra pair of brackets.
Just to clarify the [0] points to the first value in the numberarray ?
Also does this turn var Zt=[];into an array?
So again many thanks.

Brian yes the node is for Z(t) movement of your Variable Pitch Helix.
I just wanted to see if I could cut the amount of connections that
my original nod file had by doing the movement calcs within the node.
I've attached a working node.
Cheers
Barry

Hello Barry,

>>>>Also does this turn var Zt=[];into an array?
Yep! It's the same like var Zt=new Array(); only shorter:-)

>>>> Just to clarify the [0] points to the first value in the numberarray ?
That's correct! The numarray is a Standard JS-Array. PointArrays are a Special datatype!

Have a nice day

Hello Friends ,
a lot of Node, so much patience but,
In the end , I think it was worth the Pen.... , as Pilou says , it's like as charm....
Tasselate a dome,
steel frame and glasses , triangular parametric pattern

best

That's Richard Buckminster dome! ;)

But seems there is something to increase!
If I am not wrong seems only 5 levels of triangulation are possible?
So maybe an another algorithm to find ?

And a complet dome ?
A truncated dome with Top/Bottom size circle variable ?



Ps Make a space inside the address link! ;)
so your link becomes (more speedy for user! ;)
