@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 ...

@cncandi It looks like you made a copy of the JSCAD website. That's really customize to support drag-n-drop, loading projects, URL options, etc. It's probably not what you really want.

Take a look at the websites and frameworks mentioned here.

Let us know if you have any more questions.

@Hermann-SW Good questions...

The website has a little Perl script that does the download of the requested file, and checks the content. This does two things; only know file types are allowed, and this goes around CORS.

https://github.com/jscad/OpenJSCAD.org/blob/master/packages/web/remote.pl

I guess that supporting data URL would be possible, but there would have to be some similar checks for data type, etc.

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!

@David-Bolt The latest release has a change which retains the webworker thread. So, debugging should be easier now.

@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.

@david-bolt one suggestion from what i've tried could be to set the camera position for regular perspective camera further away as an orthographic camera is just a perspective camera at infinity

Yes, this becomes quite limiting if one has to have users download, unzip, and drag & drop. Kind of defeats the purpose of projects. Also you'd have to deal with updates.
Very cumbersome for non-tech users.
It would be nice if you could include directories or even zip files in the URL.

@platypii Thank you for this investigation. I remember that I tried to get JSCAD to union those groups but then it loses colors. I use Wings 3d to colorize my models, and it does not split them into separate objects (on my screenshot I have only one geometry), only materials are separated into groups.

I splitted the model into 3 geometries and then exported it to .obj and the difference is that it contains 3 lines starting with "o " that defines start of an object. Maybe for the moment JSCAD translate lines starting with "g " like "o ".

We're almost at 2000 commits too! 1997 commits now.

@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
