@Lukasz – there is a post by @villares on making the JCSG Constructive Solid Geometry library work with Processing in both Java and Python modes.

> For years I have looked for CSG in Processing… then I found a nice Java CSG candidate library and George Profenza in minutes made it work with Processing: I’m very happy smiley And it even works with my beloved Processing Python Mode: [https://github.com/villares/py.processing-play/tree/master/3D/demo\_JCSG\_py](https://github.com/villares/py.processing-play/tree/master/3D/demo_JCSG_py) Now the next step, I guess, would be someone skilled in the ancient Processing Library template & repository maintenance arts to wrap it and make it…

You should also look at the discussion on his Stackoverflow post with the original question and an amazing detailed answer by @George. @Chrisir also made a demo – I’m not sure, but he may also use JCSG in some of his movies?
