Hi Alice found a paper
http://folk.uib.no/mna024/papers/sketch/EG05_Masry.pdf ( use of tetgen for scetches ) ( I believe there are a lot other papers, but they seem need to be included into application ) and also recalled ( after looking into http://code.arc.cmu.edu/archive/dmgftp/public_html/publications/pdfs/acadia98-mdg.pdf ), that UnlimitedClay by Farsthary ( which is about to be out some day look for him mails in archive ) might be of some use at least you might request him how his code might be used in your case - because he builds meshes like pushing clay ( so no polygon rendering ) the difference is that he also dynamically changes them and you need just to fill what is rendered by pen.
