Rachel Probert's CRA-W Experience
Non-Photrealistic Rendering (NPR) is the way that graphics hardware, guided by software, draws pictures on your screen. The polygons, some generated on your Graphics Processing Unit and some by Software are passed to buffers which render them on screen. Before it is complete however, silhouettes and other shadows must be drawn. Much of the current research in this area focuses on how to choose the shadows to be drawn. The most successful Rendering software has won an Academy Award! for significant advancements to the field of motion picture rendering as exemplified in Pixars RenderMan. the Pixar site discusses their RenderMan software and the movie-making process they designed.
This is only a partial list of the papers I have read, it may grow as more become internet ready.
Bruce and Amy Gooch's work is cited repeatedly as a way to find and render silhouettes.There is also some interesting collaborative work done with other Research Scientists and Proffesors at 'The U', take a look at Interactive Technical Illustration . Their book, Non-Photorealistic Rendering is a good place to begin reading on the basics of NPR.
