Thanks to the browser cache I was able to run the script again and it already had all values loaded and I only needed to change the slider that was badly positioned.

@gilboonet vool 🙂 . Nice to see it working

@z3dev I finally resolved it by not using transforms and directly compute the center of the rectangles, that way the geometry sides were ok without any need to transform. I hope to be able to reuse that code for same kind of simple designs.

@gilboonet the example looks fine. You can create, rotate, transform all the math objects..

Now comes the fun part... curves, distances, etc. There are little tidbits of logic throughout the library. You can find some of the basic calculations in the primitives, I.e. arc, circle, sphere, etc.

And of course, let us know if you have questions.

@hrgdavor That would be great. For the moment I'm certainly going to try to do the same thing using svg into vanilla js.

@z3dev Bonjour,
j'ai bien réussi à créer cette forme avec les "paths / expand / offset".
mais cela me pose beaucoup de problèmes pour la suite, à savoir, le positionnement des perçages. En effet c'est compliqué car l'angle de pliage peut varier en fonction des utilisateurs.

J'ai trouvé une fonction OPENSCAD qui effectue exactement ce que je souhaite. Est-il possible de mettre cela en place sur JSCAD

Je n'arrive pas bien à comprendre la logique de son code qui est "en vrac" dans la description de la vidéo.

Je vous remercie pour le temps que vous consacrerez à ma demande.

@Hermann-SW Thanks for all the super insights to your designs. It has been great to see you continue and improve the designs, and finally have a great base for more designs.

I haven't seen anyone compare JSCAD to OpenSCAD viewers. We continue to improve the viewer (and modeling library) so it's really nice to have some complements. 😃

We have had some recent performance improvements, based on @platypii and @briansturgill changes. And we have more planned ahead.

@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 ...

I implemented optional JSCAD output for planar graph playground "node.tetra.js", details here:

Until now I played with C20 hand edited for JSCAD, this is newly created C60 fullerene with 60 vertices and 90 edges:

More vertices and edges than for C20, but design regeneration still done in less than 10 seconds on Intel it Linux Chrome!

@ajw1970 super!

I'm interested in the final application. Why did you want to use Babylon for rendering? And do you further plans to create some online designs?

@z3dev ok, thank you very much for your feedback

@hrgdavor Thank you, I will try from this demo.html file. I already used that file at early stage of V2 to take snapshots of a scene to create an animation, but I'm not sure I understood it all.

I changed my obj importer code to make it work with obj without groups. Now I can start to colorize my models by code. And there's one nice thing about that : I can use that faces coloring to store a volume's unfold pattern.

@udif great question!

There are three main objects; geom3, geom2, and path2. You can create empty versions of these…

const a = geom3.create() const b = geom2.create() const c = path2.create()

@gilboonet that is definitely something worth considering either as part of jscad or an addon library. I think we will have better idea after I have some time to cooperate with you on your project. It is definitely an interesting use-case, and a real project will give much needed insight on how to proceed with it.
