View-Dependent Particles for Interactive Non-Photorealistic Rendering

Authors:Cornish, Derek, Department of Computer ScienceUniversity of Virginia Luebke, David, Department of Computer ScienceUniversity of Virginia

We present a novel framework for non-photorealistic rendering based on view-dependent geometric simplification techniques. We represent the model as a system of particles, which may optionally overlay a polygonal surface. A hierarchical view-dependent clustering algorithm regulates the number and placement of these particles, which are rendered as strokes in the final image. This algorithm thus unifies several tasks common in artistic rendering, such as placing strokes, regulating the screen-space density of strokes, and ensuring inter-frame coherence in animated or interactive rendering. View-dependent callback functions determine which particles are rendered and how to render the associated strokes. The resulting framework is interactive and extremely flexible, letting users easily produce and experiment with many different art-based rendering styles.
