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. 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. 　All phenomena of our ink painting system are simulated in real-time so user can freely manipulate brush bristle to add paint or interact with paint for painting. Furthermore, we propose two methods to accelerate ink simulation. Both methods are implemented using special functionalities on the modern graphics hardware. As a result, our speedup implementation ranges from 3 to 10 times faster than original one.
