Dynamic Chinese Ink Rendering Based on Fluid Simulation

The Chinese ink-painting is a unique branch of non-photo realistic rendering(NPR)[1] and focused by researchers for its eastern Chinese style. However, most people only pay attention to static ink rendering, and the dynamic ink rendering process has been little concerned. As the development of fluid simulation, the interaction of different kinds of fluid or fluid and solid can be simulated better, faster and more clearly. But few people made use of fluid simulation into ink rendering. In this paper, we analyze Navier-Stokes equations, ray casting and CUDA, combine them to simulate Chinese ink rendering. We mainly use fluid simulation to simulate the physical properties and the co actions of ink and other material, also to improve the visual effects and speed, the GPU technology and ray casting are applied. Finally we completed a 2D ink simulator, a 3D ink simulator and try to use them to express the style of ink, and get some effect.
