some sporty shades… The goal here is to use subd where it’s appropriate, and use nurbs where appropriate, This will require some thought and planning to allow yourself the creative freedom to iterate, and not commit to nurbs too early. Aim for Lightness, get as much as you can out of as few faces as possible. remove stuff and simplify where ever you can… bonus for rendering it up in v7 rhino render.
Hint, pro shade designers start from the lenses (or so I’ve been told) I started from the frames and finished with the lenses, after doing it wrong, I can see why you work from the lenses out…
this model with the rendering took about 1.5 hrs and included a lot of iterating and general mucking about to get a shape that I was semi happy with.
