Last year I grew fond of it to design ever more complex models, but started running into limitations: while interactive rendering was fine, the final rendering (creating the STL files to give to the 3D printing slicer) was horrendously slow. A simple declarative programming language defines Constructive Solid Geometry (CSG) operations like unions, intersections, differences, which can be parameterized with loops and variables.
#Openscad for software
It’s essentially a CAD software for programmers with a minimalist UI. OpenSCAD is a popular open-source design tool for 3D printing afficionados (and others).

Rewriting trees to increase laziness and parallelizability.What about multithreading? Or skipping operations altogether? ?.CGAL’s other hidden gem: corefinement functions.CGAL Nef Polyhedra + GMP = so precise it hurts (performance).

Note: opinions expressed here are my own. Make your models more ambitious and report issues / successes here! TL DR: OpenSCAD users: download a nightly build & enable fast-csg in settings for 10x faster render (YMMV).
