OK...I'm really impressed by my experiments with Autodesk's 123D suite of apps. This is mostly math, and not much artistry on my part, but the results are outstanding. I took about 12 pics of my Clint Eastwood lifecast with my iPad and the 123D Catch app output a pretty swell 3D model. This model was then export to my Zbrush program for a quick render. As a basis for a clean, workable 3D model...this is perfect. I wish I had this tech a few years ago!
