Interactive cage generation for mesh deformation

Abstract

Many previous efforts have been focused on generating optimal coordinates for cage deformation; cage generation for 3D models has been relatively understudied. We introduce an efficient complete pipeline to generate high quality cages for 3D models with arbitrary topological complexities, including high genus models and those without perceptible skeletal structures. Specifically, starting from user-specified cut slides, our method automatically optimizes the consistent, orthogonal orientations of cage cross sections. Then, through automated cage meshing and refining, it can further improve the cage quality by tackling the cage coverage issue and bounding the input model with a controllable tightness. Our experiments demonstrate this approach is efficient and robust to handle a variety of 3D models including human-like, animal, and high genus models.
