you could do what that program does manually. Take a picture of you're "subject" or sketch it from 2 or 3 axis and then trace around it by manually placing vertecies where they would go. This is how people generally model cars, faces ect. Then you hit a "fill" button all the pollys are added then you just clean it up.
