Yes, I wrote co_former with Processing and those 3 libraries. It is not too different from hemeshGui by Amnon Owed, except that mine is stripped down, imports STLs, and has some custom algorithms based on hemesh.
#ccc is the other sketch of mine that adds colour information to produce colorSTLs. For that you need a bit of code found inside toxiclibs, which I’d like to reveal how to implement.
I’m in the process of releasing bits and pieces of code. I’m not an expert code sharer but I’m setting up github and commenting my code so that I can help others out. Is github the thing to do these days? Or do people prefer openprocessing.org? Send me a tweet answer to @m_pf thanks!
