I'm writing a book on 3D Technology in Fine Art and Craft. I'm featuring a section on The Digital Michelangelo project and have a question. Professor Levoy talks about the drill marks in the hairline on this section of the David.
Can someone please explain why these would be there. I know nothing about carving in stone or about the process of Michelangelo.
Thanks in advance. http://graphics.stanford.edu/project...-w-laser-s.jpg
