Diffusion curves are effective 2D vector-graphics primitives, for creating smoothly-shaded drawings with rich colors and unique styles. Conventional drawing systems for diffusion curves often require users to successively layout curve geometry and then specify colors, which is rather tedious for complex drawings. This paper proposes a novel multi-touch sketching interface for efficient design of 2D vector graphics with diffusion curves. In sharp contrast to previous interfaces, we develop a family of multi-touch gestures, allowing users to simultaneously sketch multiple diffusion curves and also to interactively edit and tune curve geometry and colors. Our experiments show that this not only brings novel painting experience to users but also provides a practical and effective tool for vector graphics design, useful for styles like silk painting, Disney cartoon, art poster, and photo-realistic effects. Lastly, we conduct a user study to explore the interface's intuitive and efficient drawing capability with both professional 2D artists and novice users.
