Sensor-aware Normal Estimation for Point Clouds from 3D Range Scans
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Normal vectors are essential for many point cloud operations, including segmentation, reconstruction and rendering. The robust estimation of normal vectors from 3D range scans is a challenging task due to undersampling and ... -
Constructing 3D CSG Models from 3D Raw Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The Constructive Solid Geometry (CSG) tree, encoding the generative process of an object by a recursive compositional structure of bounded primitives, constitutes an important structural representation of 3D objects. ... -
Möbius Registration
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Conformal parameterizations over the sphere provide high-quality maps between genus zero surfaces, and are essential for applications such as data transfer and comparative shape analysis. However, such maps are not unique: ... -
Modular Latent Spaces for Shape Correspondences
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We consider the problem of transporting shape descriptors across shapes in a collection in a modular fashion, in order to establish correspondences between them. A common goal when mapping between multiple shapes is ... -
Statistical Modeling of the 3D Geometry and Topology of Botanical Trees
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose a framework for statistical modeling of the 3D geometry and topology of botanical trees. We treat botanical trees as points in a tree-shape space equipped with a proper metric that captures the geometric and the ... -
Principal Geodesic Analysis in the Space of Discrete Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Important sources of shape variability, such as articulated motion of body models or soft tissue dynamics, are highly nonlinear and are usually superposed on top of rigid body motion which must be factored out. We propose ... -
Field-Aligned and Lattice-Guided Tetrahedral Meshing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a particle-based approach to generate field-aligned tetrahedral meshes, guided by cubic lattices, including BCC and FCC lattices. Given a volumetric domain with an input frame field and a user-specified edge ... -
QuadriFlow: A Scalable and Robust Method for Quadrangulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)QuadriFlow is a scalable algorithm for generating quadrilateral surface meshes based on the Instant Field-Aligned Meshes of Jakob et al. (ACM Trans. Graph. 34(6):189, 2015). We modify the original algorithm such that it ... -
Hierarchical Quad Meshing of 3D Scanned Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we present a novel method to reconstruct watertight quad meshes on scanned 3D geometry. There exist many different approaches to acquire 3D information from real world objects and sceneries. Resulting point ... -
Fast Approximation of Laplace-Beltrami Eigenproblems
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The spectrum and eigenfunctions of the Laplace-Beltrami operator are at the heart of effective schemes for a variety of problems in geometry processing. A burden attached to these spectral methods is that they need to ... -
An Explicit Structure-preserving Numerical Scheme for EPDiff
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a new structure-preserving numerical scheme for solving the Euler-Poincaré Differential (EPDiff) equation on arbitrary triangle meshes. Unlike existing techniques, our method solves the difficult non-linear ... -
A Unified Discrete Framework for Intrinsic and Extrinsic Dirac Operators for Geometry Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Spectral mesh analysis and processing methods, namely ones that utilize eigenvalues and eigenfunctions of linear operators on meshes, have been applied to numerous geometric processing applications. The operator used ... -
Learning Fuzzy Set Representations of Partial Shapes on Dual Embedding Spaces
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Modeling relations between components of 3D objects is essential for many geometry editing tasks. Existing techniques commonly rely on labeled components, which requires substantial annotation effort and limits components ... -
Effective Characterization of Relief Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we address the problem of characterizing relief patterns over surface meshes independently on the underlying shape. We propose to tackle the problem by estimating local invariant features and encoding them ... -
Error Propagation Control in Laplacian Mesh Compression
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Laplacian mesh compression, also known as high-pass mesh coding, is a popular technique for efficiently storing both static and dynamic triangle meshes that gained further recognition with the advent of perceptual mesh ... -
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 ... -
Efficient Path Generation with Reduced Coordinates
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Path generation is an important problem in many fields, especially robotics. One way to create a path between a source point z and a target point y inside a complex planar domain W is to define a non-negative distance ... -
Kernel Functional Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Functional maps provide a means of extracting correspondences between surfaces using linear-algebraic machinery. While the functional framework suggests efficient algorithms for map computation, the basic technique does ... -
Topological Function Optimization for Continuous Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a novel approach for optimizing real-valued functions based on a wide range of topological criteria. In particular, we show how to modify a given function in order to remove topological noise and to exhibit ... -
Interactive Curve Constrained Functional Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Functional maps have gained popularity as a versatile framework for representing intrinsic correspondence between 3D shapes using algebraic machinery. A key ingredient for this framework is the ability to find pairs of ...
