I really like IceSL and think its getting too little attention: https://icesl.loria.fr/ https://icesl.loria.fr/ It uses lua to be scriptable much like openscad, but it's got GPU support, so you can also describe surfaces as signed distance fields - in shader code... It doesn't seem to be open source (yet?), but there are contributors listed [0] (it came out of inria, the french university, sylvain lefebvre being the lead dev[1]) Check out %appdata%\IceSL\icesl-models or thingiverse[2] for examples. edit: formatting [0] https://icesl.loria.fr/about/ [1] https://www.antexel.com/research [2] https://www.thingiverse.com/search?q=icesl
