Walk‐Through Illustrations: Frame‐Coherent Pen‐and‐Ink Style in a Game Engine

In this paper we show how a game engine designed to generate photorealistic images can be extended to produce non‐photorealistic and hybrid renditions. We introduce new hardware‐based methods to accomplish pen‐and‐ink illustrations. The combination of the highly optimized processing of a game engine and the use of hardware for NPR algorithms yields real‐time animation of pen‐and‐ink illustrations.
