Hi Karsten,

I have attempted to create a node based on RemoveDuplicates script.
however without success. Below is my attempt:

// RemoveDup
function RemoveDup()
{
this.addInput("In","objectlist");
this.addOutput("Out","objectlist");
}

RemoveDup.title = "RemoveDup";
RemoveDup.desc = "RemoveDup";

RemoveDup.prototype.onExecute = function()
{
var inObj = this.getInputData(0, moi.geometryDatabase.createObjectList());
var output = moi.geometryDatabase.createObjectList();
if ( inObj.length> 0 ) output = factory ('removeduplicates', inObj);
this.setOutputData(0, output);
}

LiteGraph.registerNodeType("Objects2/RemoveDup", RemoveDup);


Now, only if this would be a welcome distraction for you,
I would appreciate if you could steer me right.

I have so missed your contributions to NE in your long absence.
I know you have a lot on your plate, so if this is something that
you can't turn your mind towards right now, then no worries.

Hope you're well

Hello James,

After some problems in my life or with my wife, I had to find a new orientation - I think a well known problem. Now it's getting better and better and I see the light at the end of the tunnel - I hope it's not a train;-)

To your problem:

At first: I think removeduplicate needs a second input - a tolerance value, but that won't solve the problem alone. I suspect that this factory don't give a geometry list back - it works directly to the geometry database. So we have to use a workaround - 1. write the input to the database. 2 call the factory. 3 delete the input list (otherwise the database locks removing). 4. commit the factory 5. get the left objects (singletons) back and copy them in a list. 6 delete the singletons also from the database. 7 give the list to the output.

It's only a first idea - give me some days please and I will have a closer look.

I hope you are well and remain with kind regards!
Karsten

Hi Friends
I want to share with you my research in the field of "OpticalArt"
exploiting the potential of the Quartz node (truly amazing tool....
honor to Max)
A particular double propeller, as opposed moving creates the effect
looked for...
The propeller can be either a Polysurf or a Subdsurf

Have a nice day to all

Hi All,
A new Node Editor derived pattern experiment: Equilateral Triangular grid with scale of individual triangles determined by 3 attractors.

Oh & Thanks Michael for the new update

Hi James
have you read my last message in this thread ?
Thanks a lot

Hi Finema,

>> have you read my last message in this thread ? <<.

Yes, but if I remember correctly an earlier version was working for you.

I'm sorry I didn't respond. I was developing a hopefully foolproof method
but am first awaiting for another's input. Stray tuned.

Have a great weekend
James

Hi James,
yes the V6 work correctly.
Thanks a lot and have a great WE too.

Hello James,
would you please check this code:

// RemoveDup
    function RemoveDup()
    {
        this.addInput("In", "objectlist");
        this.addInput("Tolerance", "numarray");
        this.addOutput("Out", "objectlist");
        this.properties = {Tolerance: [0.005]};
    }

    RemoveDup.title = "RemoveDupCrv";
    RemoveDup.desc = "RemoveDupCrv";

    RemoveDup.prototype.onExecute = function ()
    {
        var inObj = this.getInputData(0, moi.geometryDatabase.createObjectList());
        this.properties.Tolerance = this.getInputData(1, this.properties.Tolerance);
        var output = moi.geometryDatabase.createObjectList();
        var temp = moi.geometryDatabase.createObjectList();
        if (inObj.length > 0) {
            var tempname = getUID(6);
            for (var i = 0; i < inObj.length; i++)
                inObj.item(i).name = tempname;
            moi.geometryDatabase.addObjects(inObj);
            var fac = moi.command.createFactory('removeduplicates');
            fac.setInput(0, inObj);
            fac.setInput(1, this.properties.Tolerance[0]);
            inObj = moi.geometryDatabase.createObjectList();
            fac.commit();
            moi.geometryDatabase.selectNamed(tempname);
            temp = moi.geometryDatabase.getSelectedObjects();
            var originXYZ = moi.VectorMath.createPoint(0, 0, 0); //Helppoint for a identical copy
            output = factory('copy', temp, originXYZ, originXYZ, true);
            var delfac = moi.command.createFactory('delete');
            delfac.setInput(0, temp);
            delfac.commit();
        }
        this.setOutputData(0, output);
    };

    LiteGraph.registerNodeType("Objects2/RemoveDupCrv", RemoveDup);

Have a nice day

Hi Karsten, if you put that inside of a <code></code> block here in the forum it should preserve the spacing/tab/indenting.

Otherwise HTML has the tendency to collapse white space.

Hello Michael,

thank you for the tip! Done:-)
I'm not familar with this stuff (CCS, HTML, PHP, ...)!

Have a nice day
Karsten

Hi Karsten

Thank you for the code. It does exactly what I wanted it to do, so cheers.

I cannot express how grateful I am for your efforts on my behalf.
Forever in your debt,
Thanks James

Hello James,

the removeduplicates factory uses a tolerance value to check if a curve is identical. I set the default value to the limit, what for MoI is identical in general (threshold 0.005 - someone should disagree, if I'm wrong). If you set it to 0, the factory can't find identical objects and the node gives everything back. The factory works only for curves and not for points, faces .... -please try the attached node file. If you need something for points as well - we have to program it.

Have a nice day
Karsten

p.s.: In my installation your example shows 3 points as result independent from the tolerance? What version of MoI you use 4.0Beta?

Hi Karsten,

Sorry for the confusion, my last example was different than my intention.
I thought the 3 points were all at the origin, and so I have removed the
comments & attachments from my last post so as to not perpetuate the
confusion. I should have double checked my work.

The node file is perfect as is.
Thanks again
James

PS I am using v4

---

Good to hear. I've tested it with V3.0 - so there were some doubts.

Hi All

More pattern experiments: now stretcher pattern mapped to surface; remaining planar.

Hello James!

Actually I don't have time to follow the Project Elephant "saga" but from time to time, when I can take a look at this thread, I see that you and the other guys are creating amazing stuff!

My congrats!!

Very interesting James !

Hi Friends
Scrolling through the M_RectangularGrid
posted different time ago, I noticed
that everything could be greatly lightened,
in terms of weight of the resulting file ....
how many interested people find this link:

the updated Macro
Good Work everyone

Hi Friends
I want to share this new macro
