Hi Brian

Should have said "

Requires Max's latest interface.js found here:
http://moi.maxsm.net/files/nodeeditor/interface.js

". Does now!

Let me know if that does not fix issue.

Note:
Loading a node assemblage with an obsolete node, and then saving the node assemblage from the nodeeditor canvas, may result in a node assemblage which will not work, even after the updated interface.js node has been added to the nodeeditor nodes directory.
The defective node (and assemblage) may look exactly like the good node. Re-upload the node assemblage from its original source.

Thank you James.
I had not updated the interface.js on Home computer.
I'd saved your cog node, from the nodeeditor canvas, making my copy defective.
Updated interface.js.
Defective node still would not work.
Downloaded your cog node AGAIN, from your forum post.
Now the cog node works fine.

Hello Brian,

maybe caused by JSON. If the Infos for the node are not completly availiable while saving?

Have a nice day

Circles projected to sphere by stereographic projection are not closed. (Nor for conformal map to torus.)
Maybe an isclosed check, and if so a close command...

- Brian

The node "separateObj" seems to have a bug.
The node is blocking passage of circles and ellipses, which are closed curves, in a demo of ConformalMapT

It was fairly easy to get the conformal mapping of circles and ellipses to be closed.

The Separate factory only produces output for curves which can be separated.

The separate node needs to be altered, to pass on closed curves which are made up of only one segment, (including elementary circles and ellipses, etc.)
Closed polygons should be separated for the conformal mapping. (and stereo project?)
So test for isClosed, and also check for crv.getSubObjects().length ==1.

Is there a test to tell when a curve can be separated?
EDIT: Michaels previous answer from: https://moi3d.com/forum/index.php?webtag=MOI&msg=8818.8
"The segments of a curve are returned by the getSubObjects() method which is available on every object type in MoI. A curve always has at least one segment. To see if it's made up of multiple segments you could do crv.getSubObjects().length > 1."

After study of Karsten and James code from last December, here is my modification of the
"Separate" node. The code belongs in the objects2.js file of nodeeditor.

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

    separateObj.title = "separateObj";
    separateObj.desc = "separateObj";

    separateObj.prototype.onExecute = function ()
    {
		var inObj = this.getInputData(0, moi.geometryDatabase.createObjectList());
        var out = moi.geometryDatabase.createObjectList();

        if (inObj.length > 0)
		{
            out = factory('separate', inObj); // Segments of Multi Subsegment curves.
        	for ( var i = 0; i < inObj.length; i++)
			{
				if ( inObj.item(i).getSubObjects().length === 1)
					out.addObject(inObj.item(i)); // Single SubSegment curves.
			}
	
		}
        this.setOutputData(0, out);
    }

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

I think that the problem is that the Separate factory only works on geometry objects in the geometry database.
Separate will work on the InObj array of objects, as ONE entity, but not on each curve item in the array, (without more programming).
The above code outputs, to out_slot, the results of the Separate factory, consisting of the segments of curves with more than one sub_segment.
Each inObj object in the input slot is then tested to see if it has only one sub_segment, and if so, said curve is added to the output out_slot.
(This likely does change the order of the curves.)

The conformal mapping is now working well with various input curves. I'm back to Normals...

Hi,
is there a way of producing an isect node or a way of extracting the edges from the surface I have produced using
the intersection node.
Cheers

Hello Barry,

objects2\extractEdges
objects2\intersectObj

Have a nice day

Hi Karsten,
your faster than Usain Bolt.
Many thanks
Barry

One of these days, an updated set of extension nodes, which can be found:-), would be nice.
I'm still doing some very minor "tweeking" on a few nodes...

Hi All,

I've done a psy-code-lic little gyro to trip out to.
(with extra degree of freedom to anim below)

Bigger version at https://www.instagram.com/nodeology/

Haves a great weekend

Hello James,

That's a really cool effect, with only a few nodes - more or less. Good to see you are back!

Have a nice day
Karsten

What I really need is a heated mouse, or a heated mouse box :-)
Maybe a mini heat pad...
- Brian

Maybe the Gyro node could be modified to take as input "Get by Style" node, or similar node?

Does it possible to make this sort of thing with Elephant ?

A bridge between 2 faces with a sort of variable adaptaion?
(and of course if the 2 faces are different that will be a must! !)

Hello Pilou,
no it's not possible. I've started some subD nodes in the past, but they are all outdated and dosen't work at the moment.
Furthermore the node Editor has not the Level of interaction like such a software.
Have a nice day
Karsten

THX for the efforts! ;)

Hello,
a few beginner's questions:
- is there a node bundle that works with latest beta, of February 26. Exactly, I'd like to get fillets. During this weekend I've tried to combine the code of node editor v.1.0.rc3.2018.03.09 which works nicely, together with code from construct2.js files downloaded from this thread, however only with limited success, MoI 4 beta is complaining about minimum fillet radius, sub-object naming node is missing. Obviously I'm doing something wrong, here.
- is it possible to have a node, able to import something directly from hard disk, like 3dm file or new subd from obj file into MoI. If so, we'll have a sort of usable referencing system.
- any plans for commercial version of these nodes - once such system will be enabled to work smoothly, I'd believe it will be able to dramatically improve the strength of MoI.
