fornjot VS cadhub

I agree 100%.

Truck[1] and Fornjot[2] are recent attempts in the Rust space, both are WIP.

But both seem to be going the traditional way. I.e. B-Rep that can be converted to (trimmed) NURBS.

I think if one wanted to incorporate the last 50 years of computer science, particularly computer graphics, one needed to broaden the feature set considerably.

You need support for precision subdivision surface modeling with variable radius creases (either via reverse subdivision where you make sure the limit surface pass through given constraints or using an interpolating subivision scheme that but has the same perks as e.g. Catmull-Clark).

Then you need to have SDF modeling ofc.

Possibly point based representations. If only as inputs.

And traditional B-Rep.

Finally, the kernel should be able to go back and forth lossless between these representations wherever possible.

And everything must be node-based, like e.g. Houdini. Completely non-destructive.

Fornjot seems like this question was tailored for it: https://www.fornjot.app/

I think some interesting developments are made in that sector in the form of https://github.com/hannobraun/Fornjot and https://github.com/ricosjp/truck. Let's see whether one of those will actually get anywhere near a usable level. Fornjot in particular is shaping up really well.

E.g. Rhai[2] or Lua or whatever.

And I guess if their tech is solid enough, someone will do that eventually and open a PR or fork the project. They do not use an existing geomtry kernel but do everything from scratch which makes this a very interesting endeavour.

There also seems to be a goal overlap between Fornjot and DieselCAD

I have heard of yet another in-development CAD software like OpenSCAD or CADQuery, called Fornjot. Still, these are not ideal.

I'm not opposed to someone else adopting that code and creating that crate though! (Fair warning though, Fornjot might not end up using that crate. We might still go with another approach eventually.)

also it's to early to be off much use to you, but have you heard of https://www.fornjot.app/ ? it's a very in development cad kernel that is also aiming for integration into multiple host languages.

Yes! The website and repository README have a screenshot, and there are screenshots for each model in the models/ directory.

I'm kind of interested in this issue because it's what I immediately wanted when I ran fj-app.

PS.: You may want to contact the guys from CadHub to add Fornjot to their list of code-CAD applications, and maybe take a look at the others I didn't mention if you haven't already. Also I must say that I'm not a dev of CadQuery.

Toothpaste Squeezer at Cadhub.xyz [n.b. cadhub.xyz allows you to edit/render CadQuery/OpenSCAD without installing anything on your PC, not how I do my development but very good for showing others models]

the link for this post takes you to a OpenSCAD model, worth noting there are integrations it CadQuery and JSCAD too.

Hey folks, We recently updated the CadHub homepage https://cadhub.xyz/. Why am I telling you this? Right at the top there is a "hero model" and atm it's a coffee lid and I don't think it's ideal as It's a bit of an odd part in the sense that I don't think it represents a typical CAD model too well. So I'm asking for submissions if anyone would like to have their model featured. I think what would be best would be something reasonably simple but not too simple if you know what I mean.

We absolutely want to add STL download to Cadhub. In fact since your box is hosted on Github, we actually want to build a Github integration/bot that builds and reproduces 3d artifacts with changes to master. But at the same time the customizer will be based on Github if so when you make changes to your repo the customizer will update too.

My usecase is I plan on making it part of https://cadhub.xyz/.

You can let me know your thoughts here, or on twitter, github or discord.

Super early days for me but I'm working on https://cadhub.xyz/, The idea is that it's a community sharing website for the code-cad community (think thingiverse cross codepen). I've got cascadeStudio working for the time being, but eventually, I'd like to add more. and this sounds like a easy way to integrate openJSCAD. (repo is here https://github.com/Irev-Dev/cadhub)an
