OpenSCAD vs OpenJsCad vs CoffeeScad
Last August 2012 #OpenJsCAD came into existance, and then #CoffeeScad in December 2012, but somehow this doesn’t work, and I like to share my brief experience with all 3 of them:
OpenSCAD: robust, fast preview, slow export of .stl, command-line interface, memory hungry, poor variable handling.
Which leads to a bizarre situation that OpenSCAD is fast to develop a model, but extremely slow at exporting .stl (aka “compilation”), whereas OpenJsCad and CoffeeScad are slower in the preview (csg.js) while developing a model, but faster when exporting to .stl compared to OpenSCAD. In a way, we have the worst case here.
How shall we proceed?
PS: I coded some wrapper for OpenJsCad so .scad can be translated easier to .jscad, code is here: http://www.thingiverse.com/thing:55479
