    Sphere-Meshes: Shape Approximation using Spherical Quadric Error Metrics

    We propose sphere-meshes, a new shape approximation model based on the linear interpolation of spheres on a mesh sub-structure, together with a new bottom-up approximation algorithm tailored by a the Spherical Quadric Error Metric (SQEM), with application to multi-resolution freeform shape modeling.

    Sparse Localized Deformation Components

    We propose a method that extracts sparse and spatially localized deformation modes from an animated mesh sequence. This enables editing of captured mesh animations, such as faces, full body motion, cloth animations, and muscle deformations. We present its benefit further for statistical geometry processing and biomechanically meaningful animation editing.

    Urban Pattern: Layout Design by Hierarchical Domain Splitting

    We present a framework for generating street networks and parcel
    layouts. Our goal is the generation of high-quality layouts that can
    be used for urban planning and virtual environments.
