BPM: Blended Piecewise Möbius Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We propose a novel Möbius interpolator that takes as an input a discrete map between the vertices of two planar triangle meshes, and outputs a continuous map on the input domain. The output map interpolates the discrete ... -
Deep Deformation Detail Synthesis for Thin Shell Models
(The Eurographics Association and John Wiley & Sons Ltd., 2023)In physics-based cloth animation, rich folds and detailed wrinkles are achieved at the cost of expensive computational resources and huge labor tuning. Data-driven techniques make efforts to reduce the computation significantly ... -
Maximum Likelihood Coordinates
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Any point inside a d-dimensional simplex can be expressed in a unique way as a convex combination of the simplex's vertices, and the coefficients of this combination are called the barycentric coordinates of the point. The ... -
Feature-Preserving Offset Mesh Generation from Topology-Adapted Octrees
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We introduce a reliable method to generate offset meshes from input triangle meshes or triangle soups. Our method proceeds in two steps. The first step performs a Dual Contouring method on the offset surface, operating on ... -
Neural Representation of Open Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Neural implicit surfaces have emerged as an effective, learnable representation for shapes of arbitrary topology. However, representing open surfaces remains a challenge. Different methods, such as unsigned distance fields ... -
HalfedgeCNN for Native and Flexible Deep Learning on Triangle Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We describe HalfedgeCNN, a collection of modules to build neural networks that operate on triangle meshes. Taking inspiration from the (edge-based) MeshCNN, convolution, pooling, and unpooling layers are consistently defined ... -
HexBox: Interactive Box Modeling of Hexahedral Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We introduce HexBox, an intuitive modeling method and interactive tool for creating and editing hexahedral meshes. Hexbox brings the major and widely validated surface modeling paradigm of surface box modeling into the ... -
Graph-Based Synthesis for Skin Micro Wrinkles
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a novel graph-based simulation approach for generating micro wrinkle geometry on human skin, which can easily scale up to the micro-meter range and millions of wrinkles. The simulation first samples pores on the ... -
Singularity-Free Frame Fields for Line Drawing Vectorization
(The Eurographics Association and John Wiley & Sons Ltd., 2023)State-of-the-art methods for line drawing vectorization rely on generated frame fields for robust direction disambiguation, with each of the two axes aligning to different intersecting curve tangents around junctions. ... -
Lightweight Curvature Estimation on Point Clouds with Randomized Corrected Curvature Measures
(The Eurographics Association and John Wiley & Sons Ltd., 2023)The estimation of differential quantities on oriented point cloud is a classical step for many geometry processing tasks in computer graphics and vision. Even if many solutions exist to estimate such quantities, they usually ... -
Partial Matching of Nonrigid Shapes by Learning Piecewise Smooth Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Learning functions defined on non-flat domains, such as outer surfaces of non-rigid shapes, is a central task in computer vision and geometry processing. Recent studies have explored the use of neural fields to represent ... -
Variational Pruning of Medial Axes of Planar Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Medial axis (MA) is a classical shape descriptor in graphics and vision. The practical utility of MA, however, is hampered by its sensitivity to boundary noise. To prune unwanted branches from MA, many definitions of ... -
Attention And Positional Encoding Are (Almost) All You Need For Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2023)The fast development of novel approaches derived from the Transformers architecture has led to outstanding performance in different scenarios, from Natural Language Processing to Computer Vision. Recently, they achieved ... -
VOLMAP: a Large Scale Benchmark for Volume Mappings to Simple Base Domains
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Correspondences between geometric domains (mappings) are ubiquitous in computer graphics and engineering, both for a variety of downstream applications and as core building blocks for higher level algorithms. In particular, ... -
PowerRTF: Power Diagram based Restricted Tangent Face for Surface Remeshing
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Triangular meshes of superior quality are important for geometric processing in practical applications. Existing approximative CVT-based remeshing methodology uses planar polygonal facets to fit the original surface, ... -
Cross-Shape Attention for Part Segmentation of 3D Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a deep learning method that propagates point-wise feature representations across shapes within a collection for the purpose of 3D shape segmentation. We propose a cross-shape attention mechanism to enable ... -
A Shape Modulus for Fractal Geometry Generation
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present an efficient new method for computing Mandelbrot-like fractals (Julia sets) that approximate a user-defined shape. Our algorithm is orders of magnitude faster than previous methods, as it entirely sidesteps the ... -
Factored Neural Representation for Scene Understanding
(The Eurographics Association and John Wiley & Sons Ltd., 2023)A long-standing goal in scene understanding is to obtain interpretable and editable representations that can be directly constructed from a raw monocular RGB-D video, without requiring specialized hardware setup or priors. ... -
Quadratic-Attraction Subdivision
(The Eurographics Association and John Wiley & Sons Ltd., 2023)The idea of improving multi-sided piecewise polynomial surfaces, by explicitly prescribing their behavior at a central surface point, allows for decoupling shape finding from enforcing local smoothness constraints. ...
