Abstract:

Chinese brush is an important tool in the digitalizing Chinese traditional ink-ash art. Based on the analysis of brush traits, a model of springparticle lengthening for simulation of Chinese brush is presented. The geometrical structure of brush is characterized more realistically with a spring which gradually increases in length. A dynamic equation of brush deformation is established based on the Newton’s second law, and solved with the Verlet integral method to improve computation efficiency. Simulations results show that the presented method for simulating Chinese brush and its movement is realistic and effective.
