Abstract:
Artists and illustrators can evoke the complexity of fur or vegetation
with relatively few well-placed strokes. We present an algorithm
that uses strokes to render 3D computer graphics scenes
in a stylized manner suggesting the complexity of the scene without
representing it explicitly. The basic algorithm is customizable
to produce a range of effects including fur, grass and trees, as we
demonstrate in this paper and accompanying video. The algorithm
is implemented within a broader framework that supports procedural
stroke-based textures on polyhedral models. It renders moderately
complex scenes at multiple frames per second on current
graphics workstations, and provides some interframe coherence.
