肥皂泡因其脆弱的性质和丰富多彩的外观而受到广泛赞赏。自然科学和计算机图形学已经全面研究了薄膜和泡沫的机械行为，以及薄液体层的光学特性。在本文中，我们专注于肥皂膜内的材料流动的动力学，这导致迷人的，非常详细的图案。该流动的特征在于表面活性剂浓度和Marangoni表面张力之间的复杂耦合。我们提出了一种新的化学力学模拟框架植根于润滑理论，它利用自定义的半拉格朗日平流求解器，使肥皂膜动力学的模拟球形气泡在自由流动，以及根据体力，如重力或外部空气流。通过将我们的模拟结果与在工作室环境中录制的真实世界肥皂泡视频进行比较，我们表明我们的框架首次紧密地再现了实验中也观察到的各种动态效果。
Soap bubbles are widely appreciated for their fragile nature and their colorful appearance. The natural sciences and, in extension, computer graphics, have comprehensively studied the mechanical behavior of films and foams, as well as the optical properties of thin liquid layers. In this paper, we focus on the dynamics of material flow within the soap film, which results in fascinating, extremely detailed patterns. This flow is characterized by a complex coupling between surfactant concentration and Marangoni surface tension. We propose a novel chemomechanical simulation framework rooted in lubrication theory, which makes use of a custom semi-Lagrangian advection solver to enable the simulation of soap film dynamics on spherical bubbles both in free flow as well as under body forces such as gravity or external air flow. By comparing our simulated outcomes to videos of real-world soap bubbles recorded in a studio environment, we show that our framework, for the first time, closely recreates a wide range of dynamic effects that are also observed in experiment.
