Its not so tough deciding what's porn and what's not. The 'Miller' test for whats obscene or not uses a local standard (ie, what do the local folks think) as well as a national standard (what do people across the country think). From reading above, seems there's no difficulty determining what folks think. I don't care much for the stuff that crosses the line. Nudes can be good art when done with graphite or sculpting and kept tasteful. I've not seen that kind of talent in 3d nudes ever. Something about the media that just isn't the same as hand crafted work. Heck, most look like cheap cartoons which clearly focus on the erotic rather than the beauty.
