  After a problem with spherical triangle implementation (my problem, not JSCAD problem) ...
  https://openjscad.nodebb.com/topic/378/problem-with-subtract-ing-hull-is-this-a-bug/3?_=1660487451987

  ... now spherical triangle works. I called it three times to fill one spherical pentagon:

  ,sp_tria(2,1,15) ,sp_tria(2,15,16) ,sp_tria(2,16,3) ...

  You can see spherical gray polygon from outside, and nothing of spherical polygon breaks into white sphere difference on the inside:
  https://stamm-wilbrandt.de/en/forum/JSCAD.spherical_polygon.js.png

  Click for view+rotate+zoom, design regeneration takes less than 3 seconds on Intel i7 Chrome
  (normally I use chromium-browser on Raspberry Pi OS, will test that in 2 weeks):
  https://www.openjscad.xyz/?uri=https://stamm-wilbrandt.de/en/forum/JSCAD.spherical_polygon.js
  Clicking "Enable Auoto-zoom" and "Enable Auto-rotate" results in nice animation ...

  P.S:
  Next step is to port "vtxt()" for adding text labels to vertex sphere, and "half()" for subtracting cube from inner side of vertex sphere, avoiding vertex to shine through to inside for 3Dprinting later.
  After that is done, I will make "node.tetra.js" create JSCAD output as alternative to sofar OpenSCAD output. Creating C60 with 12 spherical pentagons JSCAD file and measuring design regeneration time for it will answer whether JSCAD is usable for great circle arc edge embedding of planar graphs onto sphere: 12 spherical pentagons is 12*3=36 spherical triangles, is 72 "sp_tria2()" and 36 differences with "hull()" of 6 points (mini cubes) ...

  @Ion-0 it was great to meet up. I'm totally impressed with the amount of effort and engineering that went into the web application. Really cool stuff!

  Let us know how JSCD needs to improve to assist others.

  "https://openjscad.xyz?uri=..." is cool.
  "data:" URI scheme does not work for openjscad.xyz:
  https://en.wikipedia.org/wiki/Data_URI_scheme#Syntax

  I use this working minimal JSCAD file:
  https://www.openjscad.xyz/?uri=https://stamm-wilbrandt.de/en/forum/JSCAD.minimal.js

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

  This URI does not work:
  https://openjscad.xyz/?uri=data:text/html;module.exports=function main(){return require('@jscad/modeling').primitives.sphere({radius: 50})}

  Base64 encoding and using application/json does not work either:
  https://openjscad.xyz/?uri=data:application/json;base64,bW9kdWxlLmV4cG9ydHM9ZnVuY3Rpb24gbWFpbigpe3JldHVybiByZXF1aXJlKCdAanNjYWQvbW9kZWxpbmcnKS5wcmltaXRpdmVzLnNwaGVyZSh7cmFkaXVzOiA1MH0pfQo=

  It would be cool to have "data:" links working with openjscad.xyz, because that would allow to share JSCAD files without storing them anywhere — they are stored as part of the link ...

  For looking where&how to add "data:" scheme: How is "dist/jscad-web.min.js" generated?

  P.S:
  My GraphvizFiddle tool does not support links, but stores graphviz files in URL percent-encoded; click and see:

  @gilboonet that is excellent, it may be possible later on to integrate that one with jscad or at least take your experience for ideas how to improve 2D use-cases in jscad.

  Valine Zeigler
  Greetings Everyone!
  What video or website do you suggest for a total JSCAD beginner.
  Specifically, 5 middle schoolers were challenged to create ancient Egyptian artifacts using jscad.
  How do you suggest we begin?
  Thank you for any references.

  Valine Zeigler Gilbert, Thank you so much. You were so helpful that I found Tinkercad. After watching your video I realized that jscad may be the next step for those who want to dive deeper after learning the basics. Have a great day!
