| Abstract | Many painters today are going digital, because of the convenience and ease of experimentation that painting software gives. Existing software such as Corel Painter already effectively simulates the effects of various art media, including chalk, pencil, and oil. Add some after effects, such as embossing and lighting, and an untrained eye would find it difficult to distinguish between paintings created digitally and those created conventionally. Nevertheless, tools for creating digital Eastern brushwork are still lacking, as some artists and researchers realize, 1-4 primarily because existing brush models can’t simulate the delicate realtime brush deformations needed for this traditional art. Our goal is to effectively simulate the process of brush painting—particularly the dynamics of a brush tuft—so that artists can use a virtual brush to paint with spirit—that is, in a lively, dynamic, brisk way (see the “Eastern Brushwork” sidebar). We’ve designed an efficient deformable brush model with spreading bristles that works in real time with consumer-level hardware. (The preliminary results of this work are available elsewhere. 5 A 3D virtual brush’s bristles bend and spread realistically like a real Eastern paint brush.

Our research thus far focuses on brush modeling and ink depositing from brush to paper. The simulation of ink diffusion on paper, another important feature of Eastern brushwork, is a future goal. Ultimately, we expect a complete painting system to lead to new graphics tools for ■ creating digital brushwork with spontaneity and personal style, ■ rendering high-resolution Eastern fonts with the aesthetic quality of real calligraphy, and ■ rendering 3D objects in an Eastern painting style. Why 3D? It’s possible to draw any shape using a 2D mark-making method by either dragging curve control points or painting with variable dab size. Moreover, simulating Nelson S.H.
