Complex Wrinkle Simulation and Robust Surface Remeshing

Abstract

In this thesis, I accurately simulate intricate wrinkles under coarsely meshed thin shells. We first propose a novel wrinkle model that adeptly captures complex, high-frequency wrinkles on coarse meshes, overcoming the resolution constraints of traditional Finite Element Method frameworks. This model is then extended to facilitate the animation of detailed wrinkle dynamics, including the progression of singularities. Moreover, we introduce an advanced remeshing technique that seamlessly converts high-polygon models—common in natural environments—into visually equivalent low-polygon meshes. This technique proves invaluable not only for preprocessing to generate coarse meshes suitable for our wrinkle simulation approach but also for creating models with multiple levels of detail (LOD), a technique widely utilized in the gaming industry.
