well travis, you're right, almost no organic surfaces in reality are perfect, but, it's much faster and more effective to work with nurbs. When I lokk at the models, brayetech did in the above thread, I like 'em, but they almost got no muscle definition and I think, when it comes to this part of work (adding detail without destroying the main look of the model), NURBS are much more effective. Then there's the programming-part. Did you ever started programming in openGL or sth. similiar ? Whenn you program visualisation-routines for SDSFs you writing crap most the time. NURBS are much more simple to use. In th end, it's in the decision of the artists what to use for their images/anims. Most work is done by the antialiasing-routines no matter which method you use.
