List of programmatic 3D modelling tools

Code: DSL libraries for CSG, CSG software, ...

• B-Rep – OpenSCAD – OpenSCADs website – (uses CGAL under the hood – C/C++)
  

Interestingly OpenSCAD ...

• ... is a 100% pure/denotative/side-effect-free by design. But as of 2021 it ...
• ... is not a higher order functional language with functions as "first class citizens".

There are quite a few copycat projects of OpenSCAD around.
Unfortunately they all seem to fail to implement a hard guarantee on code purity – (inheriting impurity from their substrate language).
Beyond OpenSCAD of the software artifacts listed here only implicitcad can give hard guarantees on purity (there enforced by types).
