Definition

Non-photorealistic rendering denotes image synthesis techniques that apply illustrative, stylistic, and artistic depiction techniques to generate visual representations that partially or completely dismiss photorealism in favor of abstraction. With non-photorealistic rendering cartography and GIS obtain an innovative technology for designing and implementing of user and task oriented visualization systems and applications; it facilitates the implementation of visualization techniques that take into consideration, for example, cartographic design principles and specifics of geoinformation display.

Terminology

Since around 1990, NPR has established itself as a key category and discipline in computer graphics. Most researchers agree that the term “non-photorealistic” is not satisfactory because the notion of realism itself is not clearly defined nor its complement, the non-photorealism.
