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 ... -
A Variational Taxonomy for Surface Reconstruction from Oriented Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The problem of reconstructing a watertight surface from a finite set of oriented points has received much attention over the last decades. In this paper, we propose a general higher order framework for surface reconstruction. ... -
What Makes London Work Like London?
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Urban data ranging from images and laser scans to traffic flows are regularly analyzed and modeled leading to better scene understanding. Commonly used computational approaches focus on geometric descriptors, both for ...
