Abstract
When I was invited to take on the role of associate editor in chief for special issues, I knew that my predecessors, Maureen Stone and Holly Rushmeier, were going to be tough acts to follow. CGA virtual worlds, real sounds (July/August 2002); nonphotorealistic rendering (July/August 2003); haptic rendering (March April 2004); point-based graphics (July/ August 2004); and smart depiction for visual communication (May/June 2005). Over the past fi ve years, CGA see Figure 2). For July/August 2009, Norm Badler and I coedited a special issue on virtual populace, which was my fi rst introduction to editing a CG&A special issue—a most enjoyable and rewarding experience.
