Cost Minimizing Local Anisotropic Quad Mesh Refinement
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Quad meshes as a surface representation have many conceptual advantages over triangle meshes. Their edges can naturally be aligned to principal curvatures of the underlying surface and they have the flexibility to create ... -
DFR: Differentiable Function Rendering for Learning 3D Generation from Images
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Learning-based 3D generation is a popular research field in computer graphics. Recently, some works adapted implicit function defined by a neural network to represent 3D objects and have become the current state-of-the-art. ... -
Fabricable Unobtrusive 3D-QR-Codes with Directional Light
(The Eurographics Association and John Wiley & Sons Ltd., 2020)QR code is a 2D matrix barcode widely used for product tracking, identification, document management and general marketing. Recently, there have been various attempts to utilize QR codes in 3D manufacturing by carving QR ... -
Generating Adversarial Surfaces via Band-Limited Perturbations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Adversarial attacks have demonstrated remarkable efficacy in altering the output of a learning model by applying a minimal perturbation to the input data. While increasing attention has been placed on the image domain, ... -
Integer-Grid Sketch Simplification and Vectorization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)A major challenge in line drawing vectorization is segmenting the input bitmap into separate curves. This segmentation is especially problematic for rough sketches, where curves are depicted using multiple overdrawn strokes. ... -
Interactive Sculpting of Digital Faces Using an Anatomical Modeling Paradigm
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Digitally sculpting 3D human faces is a very challenging task. It typically requires either 1) highly-skilled artists using complex software packages for high quality results, or 2) highly-constrained simple interfaces for ... -
Interpolated Corrected Curvature Measures for Polygonal Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2020)A consistent and yet practically accurate definition of curvature onto polyhedral meshes remains an open problem. We propose a new framework to define curvature measures, based on the Corrected Normal Current, which ... -
Learning Part Boundaries from 3D Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a method that detects boundaries of parts in 3D shapes represented as point clouds. Our method is based on a graph convolutional network architecture that outputs a probability for a point to lie in an area that ... -
Nonlinear Deformation Synthesis via Sparse Principal Geodesic Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper introduces the construction of a low-dimensional nonlinear space capturing the variability of a non-rigid shape from a data set of example poses. The core of the approach is a Sparse Principal Geodesic Analysis ... -
A Parametric Analysis of Discrete Hamiltonian Functional Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In this paper we develop an in-depth theoretical investigation of the discrete Hamiltonian eigenbasis, which remains quite unexplored in the geometry processing community. This choice is supported by the fact that Dirichlet ... -
Properties of Laplace Operators for Tetrahedral Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Discrete Laplacians for triangle meshes are a fundamental tool in geometry processing. The so-called cotan Laplacian is widely used since it preserves several important properties of its smooth counterpart. It can be derived ... -
Topology-Aware Surface Reconstruction for Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present an approach to incorporate topological priors in the reconstruction of a surface from a point scan. We base the reconstruction on basis functions which are optimized to provide a good fit to the point scan while ...
