Simulating oriental black-ink painting

"Soft" brushes respond elastically to the force exerted by an artist against the paper. When modeled, they effectively simulate oriental black-ink painting, eliminating unnatural spline curve editing. The interactive modeling algorithm for soft brushes lets users resize brushes and choose a particular color, texture, or type of bristles. With this unique approach, a user produces brush strokes by brush movement. Unlike the flat-brush based approach, here 3D visual information comes from the elastic deformation of bristles on the paper-crucial information in black-ink painting. We look first at the modeling process for soft brushes, then at how to effectively apply them in black-ink painting.
