GWCNN: A Metric Alignment Layer for Deep Shape Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Deep neural networks provide a promising tool for incorporating semantic information in geometry processing applications. Unlike image and video processing, however, geometry processing requires handling unstructured ...
A Parallel Approach to Compression and Decompression of Triangle Meshes using the GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Most state-of-the-art compression algorithms use complex connectivity traversal and prediction schemes, which are not efficient enough for online compression of large meshes. In this paper we propose a scalable massively ...
Computing Contour Trees for 2D Piecewise Polynomial Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Contour trees are extensively used in scalar field analysis. The contour tree is a data structure that tracks the evolution of level set topology in a scalar field. Scalar fields are typically available as samples at ...
Group Representation of Global Intrinsic Symmetries
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Global intrinsic symmetry detection of 3D shapes has received considerable attentions in recent years. However, unlike extrinsic symmetry that can be represented compactly as a combination of an orthogonal matrix and a ...
Data-Driven Sparse Priors of 3D Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a sparse optimization framework for extracting sparse shape priors from a collection of 3D models. Shape priors are defined as point-set neighborhoods sampled from shape surfaces which convey important information ...
Regression-Based Landmark Detection on Dynamic Human Models
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Detecting anatomical landmarks on various human models with dynamic poses remains an important and challenging problem in computer graphics research. We present a novel framework that consists of two-level regressors for ...
Symmetry‐Aware Mesh Segmentation into Uniform Overlapping Patches
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present intrinsic methods to address the fundamental problem of segmenting a mesh into a specified number of patches with a uniform size and a controllable overlap. Although never addressed in the literature, such a ...
A Bi‐Directional Procedural Model for Architectural Design
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
It is a challenge for shape grammars to incorporate spatial hierarchy and interior connectivity of buildings in early design stages. To resolve this difficulty, we developed a bi‐directional procedural model: the forward ...
A Visualization Framework and User Studies for Overloaded Orthogonal Drawings
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
Overloaded orthogonal drawing (OOD) is a recent graph visualization style specifically conceived for directed graphs. It merges the advantages of some popular drawing conventions like layered drawings and orthogonal drawings, ...
Packing Irregular Objects in 3D Space via Hybrid Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Packing problems arise in a wide variety of practical applications. The basic problem is that of placing as many objects as possible in a non-overlapping configuration within a given container. Problems involving irregular ...
