@Jason-Sprouse hmm...

The website doesn't have a backend service/process. Everything is handled by the browser, including loading designs.

The only trick is for designs provided an a URL parameter. In this case, the URL is posted to a little script that reads the contents, stores the file locally, and returns the URL to the local file.

Of course, some other backend service could be added.

@Hermann-SW said in Are there JSCAD user callbacks?:

tionality?

Wouldn't that also be displayed in the browser stack trace?

@Hermann-SW You are not alone! I had the same experience, back in March.

@z3dev got my first email from this user group 🙂 and daily digest. That is great news that you got this working.

@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.

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

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

@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

@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 ".

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

For those wondering, @platypii is a new member of the development team. He’s already put together some super nice fixes. In addition, he never sleeps so things are moving along at light speed. 😎

So, please let him know if there’s something missing from JSCAD.

@gilboonet yes, specification for sort functions is to

return zero if a==b return neg or positive number depending if u want to sort ASC or DESC

@gilboonet I finally take advantage of geometries id and class preservation, and created a small js node script that creates a group for all paths having the same class, and at the same time I solve another annoyance that was the impossibility to search by numbers by creating id. That's very nice.
