[Haskell-cafe] CSG options for 3D printing (was: Package takeover: OpenSCAD)

[Graham Klyne]

Hello Brecht,

This is interesting, in that it's the first I've heard of there being an 
OpenSCAD package for Haskell 😯.

I've been doing a fair bit of OpenSCAD design recently, and have frequently felt 
it would be nice express these constructs in Haskell or similar more fully 
featured functional source language.  A previous search uncovered Haskell CSG 
packages, but I didn't see anything suitable for generating 3D printing files.  
(A search just now discovered https://hackage.haskell.org/package/mecha, which 
also offers OpenSCAD output.)

I understand that one of the problems with OpenSCAD as a target language is that 
it only exports to STL files, with no primitive recognition of curved entities.  
I believe there are other 3D model representations (OBJ, 3MF?) that have 
primitives for curved elements, which in turn can be handled more smoothly by 
GCode generation software.

(For non-3D printing folks reading this: GCode being the low level "machine" 
code that drives most personal 3D printers).

Anyway, I've tagged your fork of OpenCSG and will aim to try it out sometime 
😀.   Thanks!
