libfive VS tovero

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.

Start at:

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

From another random git commit I found it it seems the project moved to being hosted on gitlab.com under the account name "kavalogic-inc" but all the repos got deleted: - https://gitlab.com/kavalogic-inc

A recent question on AutoCAD lisp pointed to the libfive C++ library with C bindings. It's GitHub page points to the Tovero 3D Modeling system (link on Gitlab). That project is not found on Gitlab.

Or https://libfive.com/, which is less clunky (but no longer OpenSCAD-based).

I thought that early on, and looked (several times!) for something else besides OpenSCAD that would fill the bill (i.e. language-based CAD). There were some dozen projects, and most of them had been abandoned. The closest I got was in using libfive, an f-rep system with a binding to Scheme. But it was too easy for me to cause it to put out no shape at all, and to take a long time doing it.
