Peter's Head
Modeling: Peter Litwinowicz
Rendering: Gavin Miller
Peter's head was captured using a Cyberware scanner. The one on the right is rendered using a form of accessibility shading. This encodes the distance to the nearest point on the offset surface. Efficient algorithms for computing this are given in my 1994 SIGGRAPH paper.
