  PicoGK is a compact and robust geometry kernel for Computational Engineering

Indeed, which is why I suggested an eDSL rather than a full-blown DSL. C# is decent at embedding domain-specific languages (fluent APIs are simple eDSLs and are fairly common). You can see the need even from their simple examples:

Although I just noticed that they also support defining objects via implicit functions, so that's neat:

• manifold

  19 611 9.0 C++

  Geometry library for topological robustness (by elalish)

Small in a relative sense compared to some larger codebase.

Here's a bit on Manifold:

and the author's blog is interesting:

In the README there is a section title "On the shoulders of giants" that probably points to the main reason. This project is a layer overtop https://www.openvdb.org/

  25 11 7.8 OpenSCAD

  OpenSCAD library for moving a tool in lines and arcs so as to model how a part would be cut using G-Code.

While I certainly appreciate the virtues of a Domain Specific Language, and that OpenSCAD has been wildly successful because of its limitations, the limitations are downright infuriating at times.

An interesting potential alternative (which hopefully won't result in a fork) is adding Python:

which I've had some success with:

ImplicitCAD is interesting --- and the (new?) ability to open files from GitHub is _amazing_ (OpenSCAD recently gained that same facility, _and_ it supports the customizer: https://seasick.github.io/openscad-web-gui/?https://raw.gith... ), but it's a heavy lift given the need to work out how to edit files, preview them, and so forth.
