My planar graph playground tool "node.tetra.js" now creates planar graph sphere embeddings for JSCAD/OpenSCAD using the "same" spherical polygon and great circle arc (for graph edges) implementations:

When playing with both models, JSCAD preview mode is much faster than OpenSCAD preview for rotating the model, not sure whether it is a simpler preview or just better. Has anybody noticed similar?

Here is sample JSCAD model to play with online:

@hrgdavor Sure, Hermann-SW.
Should I create the issue against this repo?
https://github.com/jscad/OpenJSCAD.org

9/2022 I created thread on user user callbacks:
https://openjscad.nodebb.com/topic/384/are-there-jscad-user-callbacks?_=1705433092538
Should I create a freature request issue on that as well?

Open some design in openscad.xyz, eg.:
https://openjscad.xyz/?uri=https://stamm-wilbrandt.de/en/forum/JSCAD.minimal.js

Then open the editor and press "shift+enter" to update the view.

processing,
please wait

appears on left side and disappears then.
Now press "shift+enter" again, this time

processing,
please wait

appears, but does not go away.
Appending a space to editor window and pressing "shift+enter" again works once, but does not clean up when pressed 2nd time.

So the update mechanism is not prepared for "shift+enter" cleanup for 2nd, 3rd, ... time on identical source.

Hermann.

I have minimal JSCAD file:

$ cat JSCAD.minimal.js 
module.exports=function main(){return require('@jscad/modeling').primitives.sphere({radius: 50})}
$

I have it online on my webserver as well, and can start openjscad.xyz with it easily, and it just works:
https://openjscad.xyz/?uri=https://stamm-wilbrandt.de/en/forum/JSCAD.minimal.js

Then I tried to use "data" protocol:

$ cat doit
#!/bin/bash
browser=firefox
browser=chromium-browser

$browser "openjscad.xyz?uri=data:text/plain;base64,`base64 -w 0 $1`"
$ ./doit JSCAD.minimal.js 
Opening in existing browser session.
$ 

But that URI does not work:
https://openjscad.xyz/?uri=data:text/plain;base64,bW9kdWxlLmV4cG9ydHM9ZnVuY3Rpb24gbWFpbigpe3JldHVybiByZXF1aXJlKCdAanNjYWQvbW9kZWxpbmcnKS5wcmltaXRpdmVzLnNwaGVyZSh7cmFkaXVzOiA1MH0pfQo=

Is there a reason why data scheme does not work for "?uri=data..."?
If not, can it be enabled?

I ask because this method would allow to share simple JSCAD files in the URL without storing them somewhere ...

I tested, and there is an 8KB URI length limitation on openjscad.xyz. But in case data scheme would work, maybe "...?uri=data:application/gzip,base64;..." would work as well, allowing for scripts with gzipped length of up to 6KB ...

Regards,

Hermann.

P.S:
My GraphvizFiddle tool has a similar Share button approach, allowing to share a design via URL, eg:
https://stamm-wilbrandt.de/GraphvizFiddle/?1705330894960#digraph%20G%20%7Brankdir%3DLR%3B%20JS-%3ECAD%7D%0A

Not exactly what I asked for, but OpenSCAD shows stack trace when right clicking on an object, here for "edge2()":

Has JSCAD similar functionality?

I have a JSCAD model of C36.10 fullerene graph embedded onto sphere:
https://openjscad.xyz/?uri=https://stamm-wilbrandt.de/en/forum/C36.10.concave.jscad

I would like to be able to click on a vertex, and then that vertex should be moved to centroid polar coordinate of its neighbors, like vertex 7 here:

Since JSCAD is JavaScript in browser, it should be possible to add callback for mouse click event.
But is there some helper function that tells me which JSCAD object I have clicked on I can use in callback?

@hrgdavor I tried that with openjscad.xyz and it did not work. But it does work with locally hosted demo.html !
Thanks, until now I had browser console open right, editor in middle and only half of 3D view left. After drag and drop, I can close the editor and see new graphs whenever I run node.tetra.js to produce a different x.jscad. So much easier to work now ...

@hrgdavor I follow up on graph algorithm work I stopped 28 years ago:
https://stamm-wilbrandt.de/en/TR/IAI-TR-93-10.ps.pdf
I built undirected graph library as basis already, it will grow over time. Currently output formats of the tools are SVG, PostScript, and OpenSCAD and JSCAD for sphere embeddings:
https://github.com/Hermann-SW/planar_graph_playground

All planar graphs can be 4-colored (face as well as vertex, faces/vertices sharing an edge have to get different colors), there is a linear time algorithm for 5coloring, and I have built an even simpler 6coloring algorithm: https://github.com/Hermann-SW/planar_graph_playground/blob/main/undirected_graph.js#L311-L332
Yesterday I made 6coloring work for JSCAD sphere embedding, 6coloring for embedding into the plane worked long ago:

6coloring algorithm did use 5 colors only for sphere spherical face coloring (of C60 fullerene) left:
