abstract = {Drawing surfaces using hatching strokes simultaneously conveys
material, tone, and form. We present a real-time system for
nonphotorealistic rendering of hatching strokes over arbitrary
surfaces. During an automatic preprocess, we construct a sequence
of mipmapped hatch images corresponding to different tones,
collectively called a tonal art map. Strokes within the hatch
images are scaled to attain appropriate stroke size and density at
all resolutions, and are organized to maintain coherence across
scales and tones. At runtime, hardware multitexturing blends the
hatch images over the rendered faces to locally vary tone while
maintaining both spatial and temporal coherence. To render strokes
over arbitrary surfaces, we build a lapped texture parametrization
where the overlapping patches align to a curvature-based direction
field. We demonstrate hatching strokes over complex surfaces in a
variety of styles.},
