I wonder how hard it would be to convert something like that into a 3D model. I reckon a lot of people would rather sculpt than muck around with modeling software. I am kind of surprised the big bucks companies don't model everything in the game and scan it all in already.
Anyway. I'd hate to be a full time 3D modeler. But sculptor, that might not be so insufferable. I don't know if it would work for CGI movies though, since they don't use polygons. But I reckon polygons to parametric surface conversion software is pretty good nowadays.
