To get rid of the limitations of a real sand table which is not portable and has high professional requirements of sand painting techniques, also to enhance the naturalness and interest of users' experience, an algorithm of colored sand painting simulation is proposed. The algorithm consists of two main parts: (1) Colored sand painting generation method. It uses HSV and RGB models to express color information. (2) Details processing method. It takes advantages of principle of mass conservation to simulate the sand transfer process and random perturbations for various realistic painting techniques. The experimental results indicate that our algorithm can not only present technique details in a realistic, effective, and realtime manner, but also simulate colored sand painting with fine details.
