Hi All,

I have also included in ArrayExt.js a full* set of logic gates(based on Max's "Compare" node) :
AND(a,b)
OR(a,b)
NAND(a,b)
NOR(a,b)
XOR(a,b)
XNOR(a,b)

They perform boolean logic and hence are made to operate on 1 (true) & 0 (false) inputs,
however any number greater than 0 will be interpreted as a 1 and any number not will be interpreted as 0.

*There is no distinct NOT gate, however either NAND or NOR gates will perform this function by wiring input (whether 1 or 0) into both inputs.

These node options would allow the simulation of electronic circuitry, if one was so inclined.
Other than that they may be utilised for testing certain conditions to trigger events.

James



UPDATED: New ArrayExt.js attached with bug fix

Hello friends
I want to share this exercise with you
referring to the Brainstorming Confluence Park Pavillon
from the site _ Parametric House.com _
I recreated everything with EI and I added the Flooring ...
The compositions are two enough to properly switch

Have a nice evenig to all

Ps- James , nice work with the new Array Ext ,
congratulations.....

Hello James.

Thank you for your feedback and your contribution to the common cause.
It's really fun to do.

Vladimir.

Hi All,

Continued experimentation with interwoven patterns on surfaces. (nod file attached)

James

PS. Michael thanks for the V4 update. Everything is working great!

Hi Friends
a simple umbrella .....

Hi All,

I have included a new "Shell" node in the attached construct2.js

ATM shell offset is parametric but only in normal direction. Flipping the direction is easily achieved by pairing with "Flip" node (also included)

At a later date, I will see if I can add "centreline" mode, but for now it suits my purposes.

By way of demonstration, I applied shelling to nod file previously posted (with coarser pattern and no subd smoothing) . Please also find attached.

A great weekend to all,
James



UPDATED: another simple example of shell node attached

Hi All,

I have updated construct2.js to include additional new "Extend" node which performs analogous to "Constuct/Extend" tool: extending a curve to meet a boundary curve or surface.

Have a great weekend
James

Good morning James
excellent work with the New Extension Construct2
I have a problem, as you will see from the screnshot , opening your files
shell, I get an error message .......
Does it depend on some awkward setting in my program?
I simply replaced it in the UI / Nodeeditor folder
your new script to replace the existing one

Thanks in advance

Hi All,

Al (Speedy 2000) has drawn my attention to the fact that shell node only works in V4.
I will endeavour to fix this issue, but it may be a while.

All the best to everyone,
James

Hello James,
please try this code. It seems there is sometimes a timing problem with the copy/paste stuff. Very untested.

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

 extractPts.title = "extractPts";
 extractPts.desc = "extractPts";

 extractPts.prototype.onExecute = function()
 {
 var inObj = this.getInputData(0, moi.geometryDatabase.createObjectList());
 var output = moi.geometryDatabase.createObjectList();
 var selPts = moi.geometryDatabase.createObjectList();
    var originXYZ = moi.VectorMath.createPoint(0, 0, 0);
var temp = moi.geometryDatabase.createObjectList();
	         var pts = new pointArray(false);
//////
	 moi.geometryDatabase.selectAll();
	var existings=moi.geometryDatabase.getSelectedObjects(); //Locking the database objects
	 moi.geometryDatabase.deselectAll();
////////
	 if (inObj.length > 0 )
 {  var tempname=getUID(6);
for(var i=0;i<inObj.length;i++){temp.addObject(inObj.item(i));temp.item(i).name=tempname;};
moi.geometryDatabase.addObjects(temp);
temp.setProperty('showPoints', 1);
moi.geometryDatabase.selectAll();
temp.setProperty('selected', 0);
existings.setProperty('selected', 0);
 moi.geometryDatabase.copyToClipboardCommand(temp); 
moi.geometryDatabase.pasteFromClipboard();
//setTimeout( doNothing, 500);
 selPts=moi.geometryDatabase.getSelectedObjects();
for(var i=0;i<selPts.length;i++)pts.pushPoint(selPts.item(i).pt);
if(selPts.length>0)output = factory('copy',selPts,originXYZ,originXYZ,true);
 moi.geometryDatabase.selectNamed(tempname);
        temp=moi.geometryDatabase.getSelectedObjects();
	moi.geometryDatabase.deselectAll();
        var delfac = moi.command.createFactory( 'delete' );
	delfac.setInput( 0, temp );
	delfac.commit();
	delfac.cancel();
	existings=moi.geometryDatabase.createObjectList();
 } 
 this.setOutputData(0, output);
this.setOutputData(1, pts);
 }
 LiteGraph.registerNodeType("Objects2/extractPts", extractPts);

Have a nice day
Karsten

p.s.: For V4 Michael will give us some new features in the API that will make a lot of things easier.

Thanks Karsten,

Work perfectly....I wish I had your skills. You're a champion!

Thanks again
James

Hi Karsten
this morning I saw a bit of light at the bottom
to the tunnel ..... I managed to insert your script
extrPts in Object2 -Alleluja
it works great, even with the V3 ,
you are a GREAT , and believe me ,
your "forced" absence has been very heavy
have a nice day

Ps:
Courage;
We say ... dead a pope it does another one

Hi All,

I have rewritten "Shell" node for multiprocessing and reattached "construct2.js" to earlier post:
http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1258

Here is an experiment where shelling is varied across an array of hexagon extrudes
in response to proximity of 3 attractors. Although similar could be achieved by offsetting or scaling curves prior to extrude, shelling makes the process much simpler.

James

Also requires "reRange node" in arraysExt.js to be found here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1251

Nice result!

Hi All,

I have been trying without success to write a simple node for assign a style to geometry.
See my attempt below:

// SetStyle
function SetStyle()
{
this.addInput("obj","objectlist");
this.addInput("idx","numarray");

this.addOutput("Out","objectlist");
}

SetStyle.title = "SetStyle";
SetStyle.desc = "SetStyle";

SetStyle.prototype.onExecute = function()
{
var objects = this.getInputData(0, moi.geometryDatabase.createObjectList());
var index = this.getInputData(1,index);

var output = objects.setProperty('styleIndex', index);

this.setOutputData(0, output);
}
LiteGraph.registerNodeType("Objects2/SetStyle", SetStyle);

The aim here is quite modest, but ideally the node would not just assign existing indexed styles but instead add new styles with RGB inputs prior to assignment.

Any help would be appreciated
James

Hi James, this line looks a little suspicious to me:

var index = this.getInputData(1,index);

That's passing in index which I guess is undefined at that time, and then assigning the return value to index too?

For adding new styles, you can use either:

var style = moi.geometryDatabase.addStyle();

or

var style = moi.geometryDatabase.findStyle( 'name', true /* Create if not found */ );

The second one will return an existing style if there is already one with that name, or create a new one if none of that name currently exist.

Then on a style there are read/write properties for .name and .color and the style's index value is a read only property .index .


Does that help with anything? Let me know if you're still stuck.

- Michael

Hello James,

Have a look to this:

    // SetStyle
 function SetStyle()
 {
 this.addInput("obj","objectlist");
 this.addInput("idx","numarray");

 this.addOutput("Out","objectlist");
	  this.properties = {Style: [0]};
 }

 SetStyle.title = "SetStyle";
 SetStyle.desc = "SetStyle";

 SetStyle.prototype.onExecute = function()
 {
 var objects = this.getInputData(0, moi.geometryDatabase.createObjectList());
        this.properties.Style = this.getInputData(1, this.properties.Style);
//for(var i=0; i<objects.length; i++)objects.item(i).styleIndex = this.properties.Style[0];
objects.setProperty('styleIndex', this.properties.Style[0]);
 var output = objects;
 this.setOutputData(0, output);
 }
 LiteGraph.registerNodeType("Objects2/SetStyle", SetStyle);

Have a nice day
Karsten

p.s.: Don't forget - you are working with Arrays!!! It's not like arays in C, where the adress/name points to the first element;-)
