3D Motion Completion in Crowded Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Crowded motions refer to multiple objects moving around and interacting such as crowds, pedestrians and etc. We capture crowded scenes using a depth scanner at video frame rates. Thus, our input is a set of depth frames ... -
3D Shape Segmentation and Labeling via Extreme Learning Machine
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a fast method for 3D shape segmentation and labeling via Extreme Learning Machine (ELM). Given a set of example shapes with labeled segmentation, we train an ELM classifier and use it to produce initial segmentation ... -
As-Conformal-As-Possible Surface Registration
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a non-rigid surface registration technique that can align surfaces with sizes and shapes that are different from each other, while avoiding mesh distortions during deformation. The registration is constrained ... -
Blue-Noise Remeshing with Farthest Point Optimization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a novel method for surface sampling and remeshing with good blue-noise properties. Our approach is based on the farthest point optimization (FPO), a relaxation technique that generates high quality ... -
Clever Support: Efficient Support Structure Generation for Digital Fabrication
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce an optimization framework for the reduction of support structures required by 3D printers based on Fused Deposition Modeling (FDM) technology. The printers need to connect overhangs with the lower parts of the ... -
Compressed Manifold Modes for Mesh Processing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces compressed eigenfunctions of the Laplace-Beltrami operator on 3D manifold surfaces. They constitute a novel functional basis, called the compressed manifold basis, where each function has local support. ... -
Cross-Collection Map Inference by Intrinsic Alignment of Shape Spaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Inferring maps between shapes is a long standing problem in geometry processing. The less similar the shapes are, the harder it is to compute a map, or even define criteria to evaluate it. In many cases, shapes appear as ... -
Designing N-PolyVector Fields with Complex Polynomials
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce N-PolyVector fields, a generalization of N-RoSy fields for which the vectors are neither necessarily orthogonal nor rotationally symmetric. We formally define a novel representation for N-PolyVectors as the ... -
Discrete 2-Tensor Fields on Triangulations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Geometry processing has made ample use of discrete representations of tangent vector fields and antisymmetric tensors (i.e., forms) on triangulations. Symmetric 2-tensors, while crucial in the definition of inner products ... -
An Efficient Approach to Correspondences between Multiple Non-Rigid Parts
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Identifying multiple deformable parts on meshes and establishing dense correspondences between them are tasks of fundamental importance to computer graphics, with applications to e.g. geometric edit propagation and texture ... -
Efficient Encoding of Texture Coordinates Guided by Mesh Geometry
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we investigate the possibilities of efficient encoding of UV coordinates associated with vertices of a triangle mesh. Since most parametrization schemes attempt to achieve at least some level of conformality, ... -
Exploring the Geometry of the Space of Shells
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We prove both in the smooth and discrete setting that the Hessian of an elastic deformation energy results in a proper Riemannian metric on the space of shells (modulo rigid body motions). Based on this foundation we develop ... -
Feature-Preserving Surface Completion Using Four Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a user-guided, semi-automatic approach to completing large holes in a mesh. The reconstruction of the missing features in such holes is usually ambiguous. Thus, unsupervised methods may produce unsatisfactory ... -
Freeform Honeycomb Structures
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Motivated by requirements of freeform architecture, and inspired by the geometry of hexagonal combs in beehives, this paper addresses torsion-free structures aligned with hexagonal meshes. Since repetitive geometry is a ... -
Functional Fluids on Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Fluid simulation plays a key role in various domains of science including computer graphics. While most existing work addresses fluids on bounded Euclidean domains, we consider the problem of simulating the behavior of an ... -
Learnt Real-time Meshless Simulation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a new real-time approach to simulate deformable objects using a learnt statistical model to achieve a high degree of realism. Our approach improves upon state-of-the-art interactive shape-matching meshless ... -
Pattern-Based Quadrangulation for N-Sided Patches
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose an algorithm to quadrangulate an N-sided patch with prescribed numbers of edge subdivisions at its boundary. Our algorithm is guaranteed to succeed for arbitrary valid input, which is proved using a canonical ... -
Piecewise-Planar 3D Reconstruction with Edge and Corner Regularization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a method for the 3D reconstruction of a piecewise-planar surface from range images, typically laser scans with millions of points. The reconstructed surface is a watertight polygonal mesh that conforms ... -

Pseudo-Spline Subdivision Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Pseudo-splines provide a rich family of subdivision schemes with a wide range of choices that meet various demands for balancing the approximation power, the length of the support, and the regularity of the limit functions. ...
