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.

@z3dev You can also change the model, Venus has 1000 triangles and takes 30 sec. on my laptop to unfold (ubuntu with Firefox).

@z3dev Sadly, lines already have a color (red for cuts, maroon for mountain fold and green for valley fold).

@gilboonet it is nice to see a multilingual script 🙂

@z3dev
new issue

@neonsnowcat Please try the latest version via www.openjscad.xyz

Hopefully, those missing triangles have returned to earth.

@hrgdavor Thanks a lot that's exactly what I needed,

@hrgdavor Thank you, that's very nice. It's not that I like folding things but it's a process I use to build them with cardboard

I use camera-unproject to do coordinate mapping, but the obtained coordinates are obviously wrong.

code:

const regl = this.$el const handleMouseDown = (e) => { const x = 1 - (e.offsetX / regl.clientWidth) * 2 const y = (e.offsetY / regl.clientHeight) * 2 - 1 const point = vec3.fromValues(x, y, 0.5) const { projection, view, viewport } = this.camera const combinedProjView = mat4.multiply([], projection, view) const invProjView = mat4.invert([], combinedProjView) const result = unproject([], point, viewport, invProjView) console.log('convasSize: ', [regl.clientWidth, regl.clientHeight]) console.log('viewport: ', viewport) console.log('clickPoint: ', [x, y]) console.log('unproject result:', result) } this.$el.addEventListener('mousedown', handleMouseDown.bind(this))

Could it be that I did something wrong?

@z3dev
Ok, I have submitted an issue on github.
https://github.com/jscad/OpenJSCAD.org/issues/916

@jess-yan DXF is a old nasty file format so don’t expect much. JSCAD only converts certain DXF entities. Please see the README here…

https://github.com/jscad/OpenJSCAD.org/tree/master/packages/io/dxf-deserializer

There’s a nice library that will convert from DXF to SVG.

https://github.com/bjnortier/dxf

@z3dev @jess-yan yup. it is not implemented right now. But such feature has a lot more to consider to be implemented.

It may be beneficial to start a discussion on git to see what would be expectation of such functionality and what it would take to implement it.

@jess-yan another good question!

there's an issue with the internal logic of the WEB UI that prevents the 'script' to be shown. it's not that easy to fix either.

you can use the CLI (command line) application to convert the DXF file to a script.

you can find instructions on how to use the CLI in the README file at...
