WOW! this is the most realistic 3D pics I've ever seen! I didn't notice until I opened up a picture, and even then it took me a moment to realize why the edges looked strange.
I don't know what software is used for these, but I bet is this: blender, 3d studio max, auto cad or whatever. But this is really impressive, I tought it was real porn until I saw the caracter was artificial. Whoever was working with this, this is really good. This guy can work in Pixar, Dreamworks or other studio.
