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 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.},
