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. ... -
Real-time Bas-Relief Generation from Depth-and-Normal Maps on GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)To design a bas-relief from a 3D scene is an inherently interactive task in many scenarios. The user normally needs to get instant feedback to select a proper viewpoint. However, current methods are too slow to facilitate ... -
Remeshing-assisted Optimization for Locally Injective Mappings
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Constructing locally injective mappings for 2D triangular meshes is vital in applications such as deformations. In such a highly constrained optimization, the prescribed tessellation may impose strong restriction on the ... -
Robust Region Detection via Consensus Segmentation of Deformable Shapes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We consider the problem of stable region detection and segmentation of deformable shapes. We pursue this goal by determining a consensus segmentation from a heterogeneous ensemble of putative segmentations, which are ... -
Semi-sharp Creases on Subdivision Curves and Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We explore a method for generalising Pixar semi-sharp creases from the univariate cubic case to arbitrary degree subdivision curves. Our approach is based on solving simple matrix equations. The resulting schemes allow for ... -
SUPER 4PCS: Fast Global Pointcloud Registration via Smart Indexing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Data acquisition in large-scale scenes regularly involves accumulating information across multiple scans. A common approach is to locally align scan pairs using Iterative Closest Point (ICP) algorithm (or its variants), ... -
Supervised Learning of Bag-of-features Shape Descriptors Using Sparse Coding
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method for supervised learning of shape descriptors for shape retrieval applications. Many contentbased shape retrieval approaches follow the bag-of-features (BoF) paradigm commonly used in text and image ... -
Transductive 3D Shape Segmentation using Sparse Reconstruction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a transductive shape segmentation algorithm, which can transfer prior segmentation results in database to new shapes without explicitly specification of prior category information. Our method first partitions ...
