This paper presents a real-time non-photorealistic rendering technique that provides expressive depictions of 3D city models, inspired by the tradition of artistic and cartographic depictions typically found in bird’s-eye view and panoramic maps. We define a collection of city model components and a real-time multi-pass rendering algorithm that achieves comprehensible, abstract 3D city model depictions based on edge enhancement and stylization, color-based and shadow-based depth cues, and procedural facade texturing. Non-photorealistic rendering facilitates the implementation of effective visual interfaces to urban spatial information and associated thematic information going beyond the Virtual Reality paradigm and offering a huge potential for graphics design. Primary application areas include city and landscape planning, cartoon worlds in computer games, and tourist information systems.
