With the recent development of stains simulation on warp-weft style fabric materials, high realistic visual effects of real-life stains can be plausibly simulated effectively. However, the previous method relies on the limited single solvent dyeing assumption, while in the real world, the fabric is often contaminated by different stains simultaneously. To tackle the multi-stains simulation problem, we propose a novel duel-stage solvents computational model (DSSM-TLM), which essentially extended the triple-layer model (TLM) (Zheng et al. in IEEE Trans Vis Comput Graph 25(7):2471–2481, 2019. https://doi.org/10.1109/TVCG.2018.2832039 ) into a more general version. We demonstrated that various effects, such as oil-water stain mixing or alcohol-water stain mixing, can be simulated correctly first ever. Moreover, the simulation process of our algorithm is consistent with the real multi-solvent liquid diffusion process on a real fabric surface.

纺织品上多溶剂污渍的模拟

随着最近对经纬样式织物材料的污渍模拟的发展，可以有效地模拟真实污渍的高度逼真的视觉效果。然而，以前的方法依赖于有限的单一溶剂染色假设，而在现实世界中，织物经常同时被不同的污渍污染。为了解决多污点模拟问题，我们提出了一种新的双阶段溶剂计算模型（DSSM-TLM），它本质上扩展了三层模型（TLM）（Zheng 等人在 IEEE Trans Vis Comput Graph 25（7 ):2471–2481, 2019. https://doi.org/10.1109/TVCG.2018.2832039 ) 变成更通用的版本。我们证明了可以正确模拟各种效果，例如油水污渍混合或酒精水污渍混合。而且，
