    Fast and Exact Continuous Collision Detection with Bernstein Sign Classification

    We present a geometrically exact CCD algorithm based on the exact geometric computation paradigm to perform reliable Boolean queries. Our algorithm is more than an order of magnitude faster than prior exact algorithms. We evaluate its performance for cloth and FEM simulations on CPUs and GPUs, and highlight the benefits.

    Co-Constrained Handles for Deformation in Shape Collections

    We present a method for learning custom deformation handles for an object, from a co-analysis of similar objects. Our approach identifies the geometric and spatial constraints among the different parts of an object, and makes this information available through abstract shape handles that enable users to prescribe deformations.

    Local Barycentric Coordinates

    We propose a new barycentric coordinate with local control based on total variation formulation. The proposed barycentric coordinates is local and smooth. These properties are quite important for many applications like mesh deformation and texture mapping. Besides, it would save a lot of storage memory with our local barycentric coordinates.

    Robust Iso-Surface Tracking for Interactive Character Skinning

    We present a novel approach for interactive character skinning relying on the recent implicit skinning framework. Our method introduce an iso-surface tracking algorithm enabling plausible skin elasticity, skin contacts between limbs as well as muscular bulge. The skin behavior is fully automatic and avoids the tedious definition of skinning weight.

    Skinning Cubic Bezier Splines and Catmull-Clark Subdivision Surfaces

    Smooth space deformation has become a vital tool for the animation and design of 2D and 3D shapes. Unfortunately, linear blend skinning methods do not trivially extend to deforming vector graphics. We propose an efficient, variational solution that keeps splines as splines and subdivision surfaces as subdivision surfaces.
