由于其复杂性和所需的真实性，模拟头发动力学是计算机动画中最具挑战性的任务之一。大量的头发使得计算和渲染非常繁琐，尤其是受到水、火等视觉效果元素的影响。在本文中，我们提出了一种基于物理的模型来捕捉湿发的特征。我们系统中的头发和毛皮可以与水粒子相互作用并改变物理模拟的重量和刚度等参数。然后在每个时间步骤对湿发应用快速内聚过程，以实现逼真的结块效果。我们还引入了一种着色模型，可以为湿发提供令人信服的外观。
Simulating hair dynamics is one of the most challenging tasks in computer animation due to its complexity and required realism. The huge amount of hair make the computation and rendering very cumbersome, especially when influenced by visual effect elements such as water and fire. In this paper we propose a physically-based model to capture the characteristics of wet hair. Hair and fur in our system can interact with water particles and change the parameters such as weight and stiffness for physics simulation. A fast cohesion process is then applied to wet hair at each time step to achieve realistic clumping effects. We also introduces a shading model that produces convincing appearance for wet hair.
