Full Version: Getting all points of a curve using a script

Show messages:  1-13  14-33  34-42

Hi Max,

although it doesn't do what I need (I don't care about control points and need in between points ON the curve. The next Beta will allow this.) your script is very interesting. Thanks.

Hey Martin,
After you get your points by array on curve or whatever method, you can get the xyz coords for your router in a file by using "savePointFile".

You can then use a spreadsheet program like excel to add any particular command values to the xyz coords listed.

Thanks BurrMan.

Martin, this is exactly what you want :))

function GetCurveControlPoints(curve)
{
	var gd = moi.geometryDatabase;
	var obj = gd.getObjects();
	obj.setProperty( 'showPoints', false); 
	curve.showPoints = true; 
	gd.selectAll();
	obj.setProperty( 'selected', false);
	
	var objectpicker = moi.ui.createObjectPicker();
	objectpicker.allowEditPoints();
	objectpicker.done();
	gd.copyToClipboardCommand( objectpicker.objects );
	gd.pasteFromClipboard();	
	var points = gd.getSelectedObjects();
	gd.removeObjects(points);			
	
	curve.showPoints = false; 
	return points;
}

var curves = moi.geometryDatabase.getObjects().getCurves();	
for ( var f = 0; f < curves.length; ++f)
{
	pts = GetCurveControlPoints(curves.item(f));
	for ( var p = 0; p < pts.length; ++p)
	{
		var factory = moi.command.createFactory( 'text' );
		factory.setInput(0, moi.VectorMath.createFrame ( pts.item(p).pt) );
		factory.setInput(1, ' xyz('+ Math.round(pts.item(p).pt.x*10)/10 + ', ' + Math.round(pts.item(p).pt.y*10)/10 + ', ' + Math.round(pts.item(p).pt.z*10)/10+ ')');
		factory.setInput(2, 'Arial');
		factory.setInput(5, 'curves' );
		factory.setInput(6, 0.5);
		factory.setInput(7, 1);
		factory.commit();
	}
}

Max,
He wants the points "on the curve", not the weighted control points. Thats a great script.

Ops, sorry.. Now I see.
Anyway, no problem :) I know how to get it. ;)

""""""" I know how to get it.""""""""

I would be happy to get that. It would be a very cool script.

Maybe a way to set the tolerance of the "samples" would be very cool too, so it's adjustable. May need a gui for that.

Excellent!

---

Those are the points Max.

Do you think you could make a checkbox to add/leave the point data labels(Like in the previous script)? That would make it ultimate for me....

Thanks again for sharing your scripts.

---

Waht is the correct shortcut for this script?!;)

thanks

---

You can put that script in a text file with an extension of .js and give it any name you want, like "anyname.js", then place that in the commands folder, then in the shortcut editor, you add your shortcut with a command of anyname. (leave the js part out of the command)

---

I sure would love to have the labels option version of the last one posted..............

---

ok, commands folder, I did made in in the ui folder, ok, sorry ... but I was a long abstinent ;) and I use first time scripts in moi

---

new version of the script.

---

The zip file appears to be empty. ?

Brian, thank you. Reuploaded. :)

Max,
That is Banner! Thanks for taking the time to do that, and also share it....

I see you made a "copy to clipboard" for the labels which is very slick.....

I suppose there would need to be one more tweak to the labeling? I didn't think about how they would stack up on various curves/situations and MoI's texts are not "blocks", so they can become kindof unmanageable.

I was trying to imagine how that would/could be handled. It may get too complex/unwieldy to give each text block an "object name" of it's value, as it's created? Or it would have to be a vertically constrained list. The only real option would be to have them orient off the positions normal, and have a "distance away from point" value for closer sets, to remain separated.

It may just remain a great option for points that aren't too close....... It can provide some quick communication in the viewport.....

Anyway, thanks again. Nice.

Somptuous!
