@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: https://forums.raspberrypi.com/viewtopic.php?p=2030546#p2030546 Until now I played with C20 hand edited for JSCAD, this is newly created C60 fullerene with 60 vertices and 90 edges: https://www.openjscad.xyz/?uri=https://stamm-wilbrandt.de/en/forum/JSCAD.C60_vtype.js 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. [image: 1655194392922-capture-d-%C3%A9cran-du-2022-06-14-10-11-33.png] [image: 1655196467063-capture-d-%C3%A9cran-du-2022-06-14-10-29-42.png] 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

@hrgdavor for the moment i have create only one field and i serialize all datas of form and i check the values in the openjscad script

progress of the mentioned prototype with suport for different wegl libs can be found here: https://github.com/jscad/OpenJSCAD.org/discussions/944 I have just made another step forward: mesh support (but with some quirks ATM) I have some lighting to fix, and also babylonjs for some weird rason uses left handed system (this adds a bit of complexity to the worker to support it properly) Also when switching viewers, if they are different orioentation currently I need to run the script again manually to get properly oriented triangles https://user-images.githubusercontent.com/2480762/162638934-7a945625-420d-4041-98fc-5735fcc34c6b.mp4
