A Subspace Method for Fast Locally Injective Harmonic Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a fast algorithm for low-distortion locally injective harmonic mappings of genus 0 triangle meshes with and without cone singularities. The algorithm consists of two portions, a linear subspace analysis and ...
Hierarchical Functional Maps between Subdivision Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We propose a novel approach for computing correspondences between subdivision surfaces with different control polygons. Our main observation is that the multi-resolution spectral basis functions that are often used for ...
Intrinsic Symmetry Detection on 3D Models with Skeleton-guided Combination of Extrinsic Symmetries
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
The existing methods for intrinsic symmetry detection on 3D models always need complex measures such as geodesic distances for describing intrinsic geometry and statistical computation for finding non-rigid transformations ...
Generating 3D Faces using Multi-column Graph Convolutional Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In this work, we introduce multi-column graph convolutional networks (MGCNs), a deep generative model for 3D mesh surfaces that effectively learns a non-linear facial representation. We perform spectral decomposition of ...
Polycube Shape Space
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
There are many methods proposed for generating polycube polyhedrons, but it lacks the study about the possibility of generating polycube polyhedrons. In this paper, we prove a theorem for characterizing the necessary ...
Exact Constraint Satisfaction for Truly Seamless Parametrization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In the field of global surface parametrization a recent focus has been on so-called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of ...
Subdivision Schemes for Quadrilateral Meshes with the Least Polar Artifact in Extraordinary Regions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
This paper presents subdivision schemes with subdivision stencils near an extraordinary vertex that are free from or with substantially reduced polar artifact in extraordinary regions while maintaining the best possible ...
Structural Design Using Laplacian Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We introduce a method to design lightweight shell objects that are structurally robust under the external forces they may experience during use. Given an input 3D model and a general description of the external forces, our ...
Object Partitioning for Support-Free 3D-Printing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Fused deposition modeling based 3D-printing is becoming increasingly popular due to it's low-cost and simple operation and maintenance. While it produces rugged prints made from a wide range of materials, it suffers from ...
Dual Sheet Meshing: An Interactive Approach to Robust Hexahedralization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
The combinatorial dual of a hex mesh induces a collection of mutually intersecting surfaces (dual sheets). Inspired by Campen et al.'s work on quad meshing [CBK12,CK14], we propose to directly generate such dual sheets so ...
