Non-photorealistic rendering techniques for motion in computer games

ABSTRACT

Still images can portray motion by using a stylized technique. Most of these techniques are commonly used for dynamic images as well (e.g., for cartoons). Typically, an artist abstracts the motion of a specific scene or animation to illustrate movement. Depicting motion in real-time environments is no less essential, and therefore a similar approach is desirable. Our approach is focused on three methods to stylize motion: squash-and-stretch, multiple images, and motion lines. A discussion of these methods for depicting motion in dynamic images and an implementation are presented in this paper. Finally, we discuss the results and conclude with the outlook for further development.
