Hi Karsten,

It seems that snaggit13 was causing the "Hole", so your latest code seems to be just fine, and enables Light and Default Dark nodeeditor, along with the ne doc dropdown.

Hi All,

Much nicer than a recent stucco expanded metal purchase.

Hi James
for what little it is worth ..
amazing result

Thanks Al

It is worth a lot,

After 2 weeks of intermittent coding, study of many nodes, mostly by Karsten, and hundreds of corrections, a node for LineWeb was created.
There are many comments in the code, which could be removed.

In addition to the LineWeb node, a simple demo node program is attached.
Copy the LineWebNode.js file in the nodeeditor Extensions folder.
This will place the LineWeb node in the Construct2 menu.
(Construct2 could also be edited to include the LineWeb node code.) Maybe Karsten or James will do this, after the node is tested?

Testing has been minimal.
Input of other objectlist types has not be tested, nor is there any code to check for other types of objectlists.

For simple curve nodes such as Line, Circle, Star, Polygon, Curve/Interpcurve, ..., wired to an Output node, what color will the curve be drawn in?

If the Output node has "--" set for Style color, the color drawn will be the Style color currently in effect for MoI:
a. when the curve output is Wired to said Output node. And Run.
b. when the curve output is Rewired to said Output node.
c. when the node program is re-Loaded and Run.

If the Output node has a Style color set in it's Info box, that will be the color drawn, at Run, or during Run, over-riding a previously wired MoI Style color.
In the current session, Switching the Output node Style color set in it's Info box back to "--", reverts to the MoI Style color previously in effect, (even if MoI Style was changed, and there was no rewire.) (The previous wired color is "remembered" for the current MoI nodeeditor session.)

Normal Distribution, Bell Curve.

UnwrapCurve node, with majority of the code from UnwrapCurve script of Michael, made compatible with nodeeditor.

Learned that script (sub) functions are located in nodeeditor basicFunctions.js. LengthSq was not in there,
but magnitude(vec) was, as well as normalizeVec(vec) and scaleVec(vec,factor).

dir.scale( 1.0 / magnitude(dir) ); code did not work properly, (Lines and curves had Unwrap length squared, but circles and stars yielded the correct Unwrap length.)

but, dir = scaleVec( dir,1/magnitude(dir) );, did work properly.

(Limited testing)
There is no code to restrict input to curves...

2 Trivial questions just for concept! :)

Does Elephant can call an existing command like the last InsertCircle by Michael ?
http://moi3d.com/forum/messages.php?webtag=MOI&msg=9266.88

If by miracle yes, send it a wished radius value can be possible?

Of course i can make differently even without the InsertCircle (because you must click at each time) ;)
Array on Curve + Boolean Union made that very well! ;)



(about Array on Curve just (re) discovered that you can move the Base's & Offset's Points during the run of it! :)

Hi Pilou,

re:
> Does Elephant can call an existing command like the last InsertCircle by Michael ?

No, not quite exactly - Elephant does not call a "command" in MoI its nodes call MoI's script functions which is also what commands call.

But it is possible to make a node that does the same thing that "InsertCircle" does though, by using the same script that the command uses. Basically it's packaged up differently.

Thx for explanations! :)

Hello Pilou,

you don't need a special node. You can do it with the known ones.

Have a nice day

Oh yeah - InsertCircle doesn't really do very much, just creates a circle and does boolean union. So yeah like Karsten says those things are available in current nodes.

But just in general the node editor doesn't call a particular MoI "command" directly by the command name, it calls script code just like a command calls script code.

- Michael

Sure :)
Now Nodes can take any selection and made an Boolean Union ? I suppose yes :)

Here is a recreational .nod file to create Mutual Pursuit Curves for your favorite creatures, one of which is located at each corner of a regular polygon.
Each creature "chases" the creature located counterclockwise.

After creating the curves with nodeeditor, switch to regular MoI entry. Then LineWeb can be used on each pair of curves, to create geometric patterns.
Tiling the patterns makes interesting graphics. Planar colors is another option.
(I may do a logarithmic array of points on a line/curve, and/or a logarithmic or geometric series of points for LineWeb.)
The inner ends of the curves can form a mini polygon. The origin is a limit. The curves are some sort of log curves.

- Brian

The main link, which shows several patterns, is: https://www.mathcurve.com/courbes2d.gb/poursuite/poursuitemutuelle.shtml

The equations used were from the linked German site: https://did.mat.uni-bayreuth.de/material/verfolgung/node5.html
Translation can be done in Chrome browser.
Translation can also be done in the Windows 10 Microsoft Edge, but it is necessary to install the free Microsoft Edge translate app. (Fairly easy to do and enable.)
(The various equations on different sites are fairly obtuse to understand.)
