Displaced subdivision surfaces of animated meshes

Abstract

We propose a novel technique for extracting a series of displaced subdivision surfaces sharing the same topology and the same displacement map from a given animated mesh. Our motion-based mesh simplification method creates control meshes with a small number of vertices but keeps the motion information. Extracted control meshes are simpler than the original meshes, and so easier to edit and take less storage. Our method uses only one displacement map for all frames, which greatly reduces the amount of data.
