looks really usefull :)

Wow! Awesome... Was wondering about csg for a long time.

ok before everybody get too excited, im using http://www.openscad.org
its a scripting language for doing cad that relies on the following to libraries: http://www.opencsg.org/ and https://www.cgal.org/
cgal is known for not being very fast (but quite accurate), so its far from being realtime.

the scripting syntax matches quite well with chaining node after node. i just pass strings from node to node and create up the script.

i tried also to use implicit cad (another scripted cad tool) which has some nice features like rounded edges with boolean mesh operations and should be faster than openscad, but i havent be able to compile it (its based on haskell).

anyways besides of the speed issues its quite usefull for generating parametric designs for 3d printing. the mesh output is very clean.

yeah :)

How I look forward!
