Non-photorealistic rendering of ink painting style diffusion

By mixing water and ink properly, ink painting obtains different concentrations to show the contrast of an object. It presents an effective rendering algorithm for ink painting that include contour drawing and interior shading to simulate the Chinese drawing. Paint model consists of water and pigments with different physical and optical characteristics. Paper and brush are modeled by multi-layers for realistic painting simulation. It proposed describes hairy brush behavior by the curving spring model on the base of the mechanical model simulation writing brush, and proposed the rice paper model to simulate by the fiber structure by considering rice paper thickness influence to water ink proliferation, In our simulation, water and pigments are not only transferred passively among paper surface, palette, and brush bristle but are also moved actively inside the paper. Experiment result for rendering example demonstrates this system can render images in impressively good non-photorealistic rendering styles.
