我们提出了一种新的方法来模拟运动中衣服上污渍的形成和演变。我们通过将着色溶液的非均匀和/或各向异性均匀化为大块的各向异性扩散张量，准确地捕捉到着色溶液在复杂针织或机织面料上的扩散。通过基于物理的模拟，还考虑了吸收、吸附和蒸发等次要影响。最后，通过评估溶液所受的惯性力(例如离心力和科里奥利力)，捕捉布料运动对污渍形状和演变的影响。运动控制方程直接在变形的三角形网格上进行时间积分，离散非弹性布，以提高效率和稳健性。通过使用脱壳布料模拟，可以通过简化的双向耦合来预计算或积分布料的变形。最后，数值实验通过再现不同织物上污渍的常见形状和行为，证明了我们的结果在实际应用中的合理性。
We propose a novel approach to simulating the formation and evolution of stains on cloths in motion. We accurately capture the diffusion of a pigmented solution over a complex knitted or woven fabric through homogenization of its inhomogeneous and/or anisotropic properties into bulk anisotropic diffusion tensors. Secondary effects such as absorption, adsorption and evaporation are also accounted for through physically-based modeling. Finally, the influence of the cloth motion on the shape and evolution of the stain is captured by evaluating the inertial (e.g., centrifugal and Coriolis) forces experienced by the solution. The governing equations of motion are integrated in time directly on a deforming triangle mesh discretizing the inelastic cloth for efficiency and robustness. The deformation of the cloth can be precomputed or integrated through simplified two-way coupling, by using off-the-shell cloth simulations. Finally, numerical experiments demonstrate the plausibility of our results in practical applications by reproducing the usual shape and behavior of stains on various fabrics.
