Abstract:
We present an algorithm for rendering subdivision surface models
of complex scenes in a variety of artistic styles using an interactively
editable particle system. The algorithm is suitable for modeling
artistic techniques explicitly by the user, or automatically by
the system. Our approach can simulate a large number of artistic
effects due to the fact that almost any type of mark made on paper
or canvas can be imitated. Any of our artistic effects is customizable
by the user through a particle editing interface. The algorithm
maintains complete frame-to-frame coherence, a characteristic required
for good animation, and runs at interactive rates on current
computer graphics workstations.
