The real-time simulation of high-resolution cloth is challenging. Speed, stability, and robustness are crucial for creating realistic physical animations at interactive rates. Hierarchical position-based dynamics (HPBD) is a cloth simulation method that focuses on real-time simulation. This article describes a new method that leverages the mesh hierarchy of HPBD to support level of detail (LoD) simulation and rendering. During the rendering of only low-resolution meshes, high-resolution simulation is paused until high-resolution rendering is required. Thus, cloth simulation can be performed effectively using LoD algorithms. The new method is demonstrated using various experimental animations. Both HPBD and LoD are widely used in real-time applications. Combining these two techniques may improve the performance and quality of real-time applications.
