Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Text-to-CAD: Risks and Opportunities
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.

Truck: CAD Kernel in Rust
I think you confuse the book/tutorial with the documentation on docs.rs.
My impression is that the former is very much a work in progress. I never looked at it until now.
The latter (and the examples in the resp. crates) is what you want to look at to see the kernel being used. E.g. https://github.com/ricosjp/truck/blob/master/truck-modeling/...
The main README has links to all the documentation of the crates.

CAD Sketcher, free and open-source project bringing CAD like tools to Blender3d
There are two Rust projects working on parametric kernels I'm aware of.
The first one, Truck[1] seems to have a company behind it, Ricos Ltd, that look like they to know what they're doing[2]. The tweet shows their product using functionality from Truck (the frontend is not OSS AFAIK).
Fornjot is an ambitious project IMHO. Their kernel is in a separate crate[3].
As for OSS code that could be a good base to either use (or port to something like Rust) for someone to write their own kernel is Ayam [4], the oldest OSS 3D NURBS modeler that is still being developed.

Fornjot (code-first CAD in Rust) - Weekly Dev Log - 2022-W21
I've been following your project with interest and was wondering if you were familiar with Truck. Its another project implementing a CAD kernel in Rust.

Fornjot – The world needs another CAD program
I will definitely keep reading and learning, as well as gaining practical implementation experience. We'll have to see how that goes, and what the solution will end up being.
> Another direction you could take is to define just the API, and use the opencascade kernel (like FreeCAD) until the rest of your code is ready.
A CAD kernel is the central dependency for any CAD program, and I feel that it would be wrong to just use one and accept its limitations. I need to be able to take ownership, to work on it directly. OpenCASCADE is a huge pile of C++ code, which is the opposite of all that. (Not saying it's wrong to use in general, just that I'm the wrong guy to work on a huge pile of C++ code.)
I've considered using Truck[1], but decided not to do that for now. I really want to see what I can come up with. If that doesn't work out, at least I'll be in a much better decision to decide what other option would be best.

Hey Rustaceans! Got an easy question? Ask here (3/2022)!
For a specific example: I am interested in working with 3D objects using Rust (maybe this is too ambitious for a newbie!) so I found a CAD kernel crate called truck which seems to be crate built of smaller crates and implementations of other libraries. How would you go about finding the most relevant info and where to start? Should I start by understanding all the smaller parts such as the gui/gpu rendering modules, or is that irrelevant and I can focus on figuring out the top level?

Text-to-CAD: Risks and Opportunities
https://github.com/gumyr/build123d :
> Build123d is a python-based, parametric, boundary representation (BREP) modeling framework for 2D and 3D CAD. It's built on the Open Cascade geometric kernel and allows for the creation of complex models using a simple and intuitive python syntax. Build123d can be used to create models for 3D printing, CNC machining, laser cutting, and other manufacturing processes. Models can be exported to a wide variety of popular CAD tools such as FreeCAD and SolidWorks.
> Build123d could be considered as an evolution of CadQuery where the somewhat restrictive Fluent API (method chaining) is replaced with stateful context managers* - e.g. with blocks - thus enabling the full python toolbox: for loops, references to objects, object sorting and filtering, etc.*

Ask HN: What would you show an interviewer if they asked you for code samples?
A template language that I wrote for generating HTML. Meant to be included as a C++ library. https://github.com/Ghoti-io/Tang
Plenty of other C++ code of mine is on Github (such as a bunch of utility stuff, a thread pool, and a HTTP server that I'm writing from scratch), even though I would only call myself an intermediate C++ programmer. I just happen to like the language.
Or, if I had to throw other stuff into the mix, a fairly recent patch to Manim (Python) that got accepted (https://github.com/ManimCommunity/manim/pull/3155).
If I were really pressed, I would dig up a lot of my Drupal (PHP) stuff that I did years ago.
