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 ... -

A Temporally Adaptive Material Point Method with Regional Time Stepping
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Spatially and temporally adaptive algorithms can substantially improve the computational efficiency of many numerical schemes in computational mechanics and physics-based animation. Recently, a crucial need for temporal ... -
MPM Simulation of Interacting Fluids and Solids
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The material point method (MPM) has attracted increasing attention from the graphics community, as it combines the strengths of both particle- and grid-based solvers. Like the smoothed particle hydrodynamics (SPH) scheme, ... -
Liquid Splash Modeling with Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)This paper proposes a new data-driven approach to model detailed splashes for liquid simulations with neural networks. Our model learns to generate small-scale splash detail for the fluid-implicit-particle method using ... -
Strain Rate Dissipation for Elastic Deformations
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Damping determines how the energy in dynamic deformations is dissipated. The design of damping requires models where the behavior along deformation modes is easily controlled, while other motions are left unaffected. In ... -
Fast Corotated FEM using Operator Splitting
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we present a novel operator splitting approach for corotated FEM simulations. The deformation energy of the corotated linear material model consists of two additive terms. The first term models stretching in ... -
