Abstract:
We present a novel framework for non-photorealistic
rendering (NPR) based on view-dependent geometric
simplification techniques. Following a common thread in
NPR research, we represent the model as a system of
particles, which will be rendered as strokes in the final
image and which may optionally overlay a polygonal
surface. Our primary contribution is the use of a
hierarchical view-dependent clustering algorithm to
regulate the number and placement of these particles.
This algorithm unifies several tasks common in artistic
rendering, such as placing strokes, regulating the screenspace
density of strokes, and ensuring inter-frame
coherence in animated or interactive rendering. Viewdependent
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.
