libfive VS libredwg

You probably have already seen this, but I would take a look at libfive for inspiration

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.

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/

This is a mid-point in Matt Keeter's research.

then Antimony (see the article at: http://hackaday.com/2015/05/29/otherworldy-cad-software-hail... ), then the current effort:

(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

I have a much better and oracti al solution: https://github.com/LibreDWG/libredwg/blob/7d9fc3da44bbdb60a4...

free is way too slow if not needed, so detect valgrind via its API. Just on valgrind to the unnecessary free dance. ASAN's memleak detector is disabled via its env.

Perl5 does its final destruction similarly, only when it has important destructors (like IO, DB handles and such) to call.

Now even for your local github action:

Behind the scenes we’re using the open source LibreDWG library to run a number of AutoCAD native commands such as DATAEXTRACTION.

I use it for reverse engineering unknown struct layouts for DWG classes. A field packing problem.

I'm using picat, a better Prolog dialect, and generate the facts automatically from C to generate the field layouts via picat automatically.

optimization problems as in compilers are extremely natural in Prolog.
