Bounding Proxies For Shape Approximation

A new bounding shape approximation algorithm that takes as input an arbitrary surface mesh, with potentially complex multi-component structures, and automatically generates a bounding proxy that is tightened on the input and can match even the coarsest levels of approximation, with application to simulation, freeform deformation, and LOD generation.

Spatiotemporal Atlas Parameterization for Evolving Meshes

This work tracks a temporal sequence of textured meshes using local remeshing operations and parametererizes it into a spatiotemporal atlas, which provides a more coherent and compact representation of geometry and texture compared to state-of-the-art results.

FlowRep: Descriptive Curve Networks for Free-Form Design Shapes

FlowRep is an algorithm for extracting descriptive compact 3D curve networks from meshes of free-form man-made shapes. The output networks provide a concise visual description of the underlying surface and can be used as a compact proxy for shape compression, editing, and manipulation.

Functional Characterization of Intrinsic and Extrinsic Geometry

This paper shows that "shape differences" based on functional maps can fully encode the discrete metric of a mesh and introduces an extension using offset surfaces to capture extrinsic distortion.
