libfive VS fscad

Guile/Scheme: https://libfive.com/

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

4. Most examples are written by non-programmers. I have seen a couple of examples of object graph printout programs, instead of building up a list of lists or objects, these programs intertwine navigating through the tree with print indentation.

That said, I just found this repo [1] which looks well written.

On the other hand, CAD software is much more complicated than most systems I interact with. CAD platforms are one of the few remaining software systems that are written for experts. Experienced practioners are very productive [2]. So programming these systems will also be complicated.

FWIW I'm trying to template a bunch of part imports and their layouts. I'm surprised that this isn't built into the system. You can edit variables for almost (almost) every input in the system, you can name variables and elevate them to file wide variables - all without touching programming. I wish importing was parameterized such that upon import I got a chance to edit the filewide variables as parameters in the new document.
