Nonphotorealistic Rendering by Q-mapping

Peter Hall

(University of Cardiff)

Nonphotorealistic rendering is an emerging as an important research direction for Computer Graphics. The goal is to produce images that are characteristic of hand-crafted pictures. Much previous work in this area has progressed by emulating physical media such as pen-and-ink, is two-dimensional, and relies on user-interaction. We introduce Q-mapping, a method that automatically renders nonphotorealistic images from three-dimensional models. Q-mapping can draw, paint, photograph, can create natural textures such as fur, and (importantly) it has its own unique styles. Its styles all derive from a single "texture" that automatically adapts to suit lighting conditions. It has uses in Scientific Visualisation and Computer Graphics.
