Abstract
Conventional digital painting systems rely on procedural rules and physical
simulation to render paint strokes. We present an interactive, data-driven painting
system that uses scanned images of real natural media to synthesize both new
strokes and complex stroke interactions, obviating the need for physical
simulation. First, users capture images of real media, including examples of
isolated strokes, pairs of overlapping strokes, and smudged strokes. Online, the
user inputs a new stroke path, and our system synthesizes its 2D texture appearance
with optional smearing or smudging when strokes overlap. We demonstrate
high-fidelity paintings that closely resemble the captured media style, and also
quantitatively evaluate our synthesis quality via user studies.
