Hi Al,

Thanks for the compliment, but to be honest I could do with your help.
I have been trying to introduce multiply points for repulsion, without success.

Although my method worked well for my intents, it is not extendable
(at least, not as far as I can see).

If you are looking for a project, perhaps you could turn your masterful skill toward this.

Hello James and Friends
I took your words to the letter, I did some small manipulation
to your node and I used the Wire as a starting point to sketch this
Construction ... a pretty original Dome I would say ....
James , your Remap macro , will be very useful -

Good Morning Alberto,

>> a pretty original Dome I would say .... <<

Yes, your architectonic reworking of my distorted field was a delight to wake up to. Great work.

However, the distribution of isoCurves around point of repulsion would, in my original, give a less elegant curvature... in fact, plugging the remapped array into z input of pointExt results in a plateaued form which accords with the isoCurves. It is not as pleasing as your form, but allows the localisation manipulation.(ie ZONE widget) see below:




Rather than upload revised .nod file here, I replaced the one attached to my earlier post:
http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1120
It can be switched between 2d & 3d with red switch node.

To make it bulge in a hemispherical form will require some added formula applied to the x and y as well as the z components. Nevertheless at this stage my interest is more, in having the 2D field distorted at multiple points (ie 2 or more points of repulsion). I don't know if that was clear in my last post. (or this one for that matter) This video will clarify: https://www.youtube.com/watch?v=PY4Byucrcpw

>> Remap macro , will be very useful <<
Yes, so useful in fact, that I believe, it should be part of the core toolkit: ie a node, or even better an option of an enhanced ReMap node that include this, as well as remapping of points as exists in Karsten's node and ideally remapping of surfaces (retopologizing).

Anyway, thank you for your inspirational work.
I look forward, as always, to your next creation
James

Hello James, Hello Al,

it's a pleasure to see your works. At the Moment i'm working on the projection node, which can be also used for evaluating the shortest distance of a Point to a curve. So you have to have some patience until I think about a remap/rescale.

Have a nice day
Karsten

"Hello - is it this you looking for - I can see it in your eyes - I can see it in your smile ..."

Not direct the closest distance, but more general. It is the project curve factory and it works also for points to curves. Please test and study. The direction mode takes the x-axis of the frame input. For closestpt it is not necessary.

        function Project()
{
	this.addInput("Objects","objectlist");
        this.addInput("Target","objectlist");
	this.addInput("Frame","pointarray");
	this.addOutput("Out","objectlist");
	this.properties = {ProjectMode:["closestpt","closestpt","direction"]};
}

Project.title = "Project";
Project.desc = "Project";

Project.prototype.onExecute = function()
{
        var obj = this.getInputData(0, moi.geometryDatabase.createObjectList());
        var target = this.getInputData(1, moi.geometryDatabase.createObjectList());
        var f = this.getInputData(2, new pointArray(true));
        var output = moi.geometryDatabase.createObjectList();
	//0 Object
	//1 Objects
	//2 projectmode
	//3 basePt
	//4 TargetPt
	//5 delete inputs
	//6 plane
	//7
	var frame = f.getFrame();

	var pFac= moi.command.createFactory( 'project' );
	pFac.setInput( 0, obj );
	pFac.setInput( 1, target );
	pFac.setDefaultDirection();
	pFac.setInput( 2,this.properties.ProjectMode[0] );
	pFac.setInput( 3, frame.origin );
	pFac.setInput(4,frame.evaluate( 1, 0, 0 ) );
	pFac.update();
        output = pFac.calculate();	
	pFac.cancel();
        this.setOutputData(0, output);
};

LiteGraph.registerNodeType("Construct2/Project", Project);

A nice day to all

Hi Karsten,

Well there was hardly any time for impatience, you've done it....and it is just perfect.

Brilliant stuff as always
James

PS This is an application where reMapRange is useful: allowing greater controls of min/max radii and extrude height.

Karsten,

Your new node is a godsend.....which makes you a....?

Here, a ptArray is deformed with a curve, which makes for a delightfully simple way of generating a parametric surface.

James



PS Karsten, if you are now open for suggestions; this is a big one: it requires 2 nodes to work in unison. Firstly a image import node and secondly a node that converts greyscale values to numArray (à la Max's heightMap script). These num values may be z value for a ptArray, however they may alternatively be radii of circles (Che) or scale values or whatever............ Could Be Good!

This not even a request, just something to get you excited about. In the meantime there is no end of fun possible with your latest node.

Hi Karsten and James
One thing friends ...
the js file for the NE (Project)
where can I find it...
you've already posted it, and I missed ...
thank you
al

Hello Alberto,

>> the js file for the NE (Project)... where can I find it..<<

Copy the code (within grey rectangle) @
http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1128

and paste into the bottom, but just above })(); of Construct2.js code.

Directory:
C:\Users\< user name>
\AppData\Roaming\Moi\nodeeditor\nodes\extensions\construct2.js

Hope this helps
James

PS If you have not already done so, also paste in code for railRevolve and Network.
Code found in posts below:

http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1085

Hi James

I think I'm wrong
I'm in difficulty with the copy and paste operations
that step by step you showed me .. I think I did not understand well
how and where to paste the script ...
can not you send me (construct2.js) already updated with it
script project inserted in .....
like you did with Network and Rail revolve,
then I'll put it in the usual directory ...
Thank you
alberto

Hi Alberto
Please find attached.
Good Luck

Hello Alberto,

Wow, I was not expecting that...really amazing animation
Keep up the great work
James

Good Morning James ,
I have to say the same thing for you ,
sincerely the Voxel file is "unsettling"
(in italiano , direi spiazzante)
Bravo, and original .....
have a nice day
ciao

Hi James,
I have downloaded your remap nod file but getting this error ( ReferenceError: Can't find variable: magnitude)
So not sure if I have all the latest additions to extensions. (I have added the one's posted by Karsten)
Any Idea's what I'm missing.
Barry
