Real-time cloth simulation with sparse particles and curved faces

In this paper, we present a novel technique for real-time cloth simulation. The method combines dynamic simulation and geometric techniques. Only a small number of particles (a few hundred at maximum) are controlled using dynamic simulation to simulate global cloth behaviors such as waving and bending. The cloth surface is then smoothed based on the elastic forces applied to each particle and the distance between each pair of adjacent particles. Using this geometric smoothing, local cloth behaviors such as twists and wrinkles are efficiently simulated. The proposed method is very simple, and is easy to implement and integrate with existing particle-based systems. We also describe a particle-based simulation system for efficient simulation with sparse particles. The proposed method has animated a skirt with rich details in real-time.
