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.

Gimp 2.99.18 Released: The Last Development Preview Before 3.0
OCCT is definitely difficult.
I am almost as far as you can get from an expert but:
For example the TNP issue derives from OCCT (or something in the stack close to it, I am not exactly sure) not really handling face naming at all.
So if you want to avoid topological naming issues (which is a hard problem in CAD), you apparently have to do some work to track before and after and reconstruct your face naming.
https://wiki.freecad.org/Topological_naming_problem
https://forum.freecad.org/viewtopic.php?t=27278
Then there are various fairly entrenched issues to do with filleting and chamfering. Basically, both these operations will fail (in FreeCAD at least, but it's OCCT at "fault") if a chamfer or fillet would completely consume an existing edge. (It also sometimes creates impossible objects when filleting, or used to).
Booleans can be slow.
And more generally, it seems if you track the FreeCAD project that OCCT can be inscrutable when things fail; error messages aren't the greatest etc.
The flip side of OpenCascade is that it seems to be highly portable and has for example been compiled to JS with Emscripten for this astonishing thing:

It's a monumental open source project, for sure, and it's definitely not nothing that we have an open source CAD kernel; these are projects that perhaps have to extend beyond the working life of an individual developer if they are to be stable. And there are loads of projects built around it.
- Better OpenSCAD?

Show HN: Dslcad a programming language and interpreter for building 3D models
If you haven't seen it you may want to check out https://github.com/zalo/CascadeStudio
From what I see, it is exposing the OpenCascade base commands directly, versus your completely new DSL, but you might be interested in a way to implement your DSL on top of such an interface such as this which takes out a lot of the extra work of having a rendering interface, exports, etc, maybe.

Ask HN: If money was no object what software would you create?
It's nowhere near ready for primetime, but you should take a look at CascadeStudio (https://github.com/zalo/CascadeStudio)

Fornjot – The world needs another CAD program
FreeCAD is GUI-based though, not code-first like Fornjot. A better comparison would be CadQuery (https://cadquery.readthedocs.io/en/latest/intro.html) or Cascade Studio (https://zalo.github.io/CascadeStudio/), both of which are code-first and based on the same CAD kernel as FreeCAD.

Support for Javascript?
It is an actual example from CascadeStudio, but I haven't looked into it enough to know how what actually happens under the hood, but I assume the following:

- PicoGK is a compact and robust geometry kernel for Computational Engineering

Question About Runtime Mesh Editing
You can find a few algorithms online (such as csg.js and libfive), but most of them are either not robust or fast enough for real-time graphics.

Show HN: Make 3D art in your browser using Lisp and math
No; Bauble doesn't know how to "rasterize" SDFs into meshes; it only knows how to raymarch them. It's theoretically possible, but it's a pretty complex problem that would take me much too long to figure out and implement. So Bauble is relegated to just making pretty pictures for now. If you want to produce meshes using SDFs, check out https://libfive.com/

Antimony – computer-aided design tool from the Lisp machine parallel universe
This is a mid-point in Matt Keeter's research.
Start at:
http://mattkeeter.com/research/thesis.pdf
then see:

then Antimony (see the article at: http://hackaday.com/2015/05/29/otherworldy-cad-software-hail... ), then the current effort:
https://github.com/libfive/libfive
(and also see: https://www.gitlab.com/kavalogic-inc/tovero "a binding of Libfive to Common Lisp, including a standalone REPL-based viewer"[https://github.com/Irev-Dev/curated-code-cad] can be integrated with https://www.gitlab.com/kavalogic-inc/clive
Currently I'm using OpenSCAD (w/ BlockSCAD as a front-end: https://www.blockscad3d.com because I prefer a sort of visual representation), but have been stymied by the lack of file I/O (I want to write out G-code).
Still looking for a 3D modeling tool which is:
- a node or block editor
- Learning CAD on Linux
- OpenSCAD 3D rendering just got an order of magnitude faster
- CadQuery –- A Python parametric CAD scripting framework based on OCCT
What are some alternatives?
cadquery - A python parametric CAD scripting framework based on OCCT
jupyter-cadquery - An extension to render cadquery objects in JupyterLab via pythreejs
psml - Python library for OpenSCAD
curv - a language for making art using mathematics
OpenJSCAD.org - JSCAD is an open source set of modular, browser and command line tools for creating parametric 2D and 3D designs with JavaScript code. It provides a quick, precise and reproducible method for generating 3D models, and is especially useful for 3D printing applications.
