Shape Proxies: Modeling the World’s Geometry With High Level Approximations

Room: Science Park Building 3, Room 063
Among the various flavors of shape analysis, shape approximation methods offer versatile frameworks to capture the essence of a 3D shape with a compact set of numbers, sometime called proxy. In this talk, I will give an overview of recent results we achieved regarding shape approximation of 3D surfaces, including Sphere Meshes, which help simplifying complex objects at extreme levels, providing multi-resolution spatial interfaces for interactive modeling systems and automatic processing chains. I will also discuss constrained approximation with Bounding Proxies, which leverage mathematical morphology for generating simplified meshes that contain their input and can be used for physical simulation, cage-based deformation or level-of-detail rendering. Finally I will extend the discussion to the general graphics pipeline and give insights on how shape proxies can be key components for numerous applications in the era of massive 3D models and smart computer graphics tools.
