My Common Lisp program Tovero uses Libfive as the backend for modeling 
and *is* SDF (signed distance field) based.  I also wrote the direct 
Guile viewer for Libfive, which can be used under in a Geiser REPL in 
Emacs, as I mentioned in my previous post:

This replaces Libfive's Studio editor.

Thanks--I hadn't seen this, and seems like a promising idea.

My other project project, Clive, provides a interface toolkit from SGI's 
Open Inventor (used in FreeCAD), for direct 3D interaction outside of 
Emacs.  Open Inventor is a quite powerful scene graph system.  My 
website on common-lisp.net doesn't do it justice--and I need to do more 
demos of it--but I have been extensively modifying it and haven't had time.

My understanding is that Dylan's Deuce has enhancements to GNU Emacs' 
buffer model which facilitates multimedia embedded directly in the 
editor, and is derived from ZWEI--an older Lisp based Emacs. It would be 
fun to get it running someday:

QEmacs is interesting too--it can embed videos using FFMpeg (developed 
by Bellard too!) directly in an editor window.  It has C based functions 
based on a subset of GNU Emacs, which might be fairly straightforward to 
wrap in Guile or other Scheme implementation for a lightweight Emacs system.
