Simulation of Fabric Wetting Based on Particle Sampling

This article proposes a novel simulation method for fabric wetting. Firstly, in order to achieve the wetting effect of the interaction between liquid and fabric, a fast sampling method for fabric boundaries is proposed, which analyzes and samples the edges and interior of the fabric triangle during the preprocessing process. Then the forces of the sampled particles and fluid particles were calculated, and the forces of the sampled particles were applied to each vertex of the fabric triangle. Finally, update the positions and velocities of fluid particles and cloth particles. In order to make the animation more realistic and simulate the wetting animation effect, the fabric sampling particles were modeled as the basic water absorption unit, and the entire wetting process was simulated using a three-step simulation method.
