Realistic Simulation of Stains on Cloth

Although many works have been done on fluid simulation, little attention has been paid to the staining effect on cloth. In this paper, we present a novel method for realistic simulation of stain effects on cloth, including diffusion of stain on cloth, as well as evaporation, deposition, adsorption, etc. We introduce a new model called NSEAM(Navier-Stokes equations for anisotropic media) to represent the movement of stain. To simulate the anisotropic texture of cloth, we adopt a multi-layer model. With our method, the interaction between stain and different types of cloth can be realistically simulated in real-time. Experimental results validate our simulation model.
