Generalized Matryoshka: Computational Design of Nesting Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper generalizes the self-similar nesting of Matryoshka dolls (''Russian nesting dolls'') to arbitrary solid objects. We introduce the problem of finding the largest scale replica of an object that nests inside itself. ... -
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 ... -
Isometry-Aware Preconditioning for Mesh Parameterization
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper presents a new preconditioning technique for large-scale geometric optimization problems, inspired by applications in mesh parameterization. Our positive (semi-)definite preconditioner acts on the gradients of ... -
Modeling and Exploring Co-variations in the Geometry and Configuration of Man-made 3D Shape Families
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We introduce co-variation analysis as a tool for modeling the way part geometries and configurations co-vary across a family of man-made 3D shapes. While man-made 3D objects exhibit large geometric and structural variations, ... -
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 ... -
Restricting Voronoi Diagrams to Meshes Using Corner Validation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Restricted Voronoi diagrams are a fundamental geometric structure used in many applications such as surface reconstruction from point sets or optimal transport. Given a set of sites V and a mesh X with vertices in Rd ... -
The Shape Variational Autoencoder: A Deep Generative Model of Part-segmented 3D Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We introduce a generative model of part-segmented 3D objects: the shape variational auto-encoder (ShapeVAE). The ShapeVAE describes a joint distribution over the existence of object parts, the locations of a dense set of ... -
Spectral Affine-Kernel Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In this paper, we propose a controllable embedding method for high- and low-dimensional geometry processing through sparse matrix eigenanalysis. Our approach is equally suitable to perform non-linear dimensionality reduction ... -
Stochastic Heat Kernel Estimation on Sampled Manifolds
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The heat kernel is a fundamental geometric object associated to every Riemannian manifold, used across applications in computer vision, graphics, and machine learning. In this article, we propose a novel computational ... -

Ternary Sparse Matrix Representation for Volumetric Mesh Subdivision and Processing on GPUs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In this paper, we present a novel volumetric mesh representation suited for parallel computing on modern GPU architectures. The data structure is based on a compact, ternary sparse matrix storage of boundary operators. ...
