L0 Gradient-Preserving Color Transfer
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper presents a new two-step color transfer method which includes color mapping and detail preservation. To map source colors to target colors, which are from an image or palette, the proposed similarity-preserving ... -
L4RW: Laziness-based Realistic Real-time Responsive Rebalance in Walking
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a novel L4RW (Laziness-based Realistic Real-time Responsive Rebalance in Walking) technique to synthesize 4RW animations under unexpected external perturbations with minimal locomotion effort. We first devise a ... -
A Lagrangian Approach to Dynamic Interfaces through Kinetic Triangulation of the Ambient Space
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In this paper, we propose a robust and efficient Lagrangian approach for modeling dynamic interfaces between different materials undergoing large deformations and topology changes, in two dimensions. Our work brings an ... -
Lagrangian Coherent Structures with Guaranteed Material Separation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures ... -
A Lagrangian Particle-based Formulation for Coupled Simulation of Fracture and Diffusion in Thin Membranes
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We propose a Lagrangian particle-based formulation for simulating deformation, fracture, and diffusion in thin membranelike structures, such as aluminium foil, rubbery films, and seaweed flakes. We integrate our model with ... -
Lagrangian Visualization of Flow-Embedded Surface Structures
(The Eurographics Association and Blackwell Publishing Ltd., 2008)The notions of Finite-Time Lyapunov Exponent (FTLE) and Lagrangian Coherent Structures provide a strong framework for the analysis and visualization of complex technical flows. Their definition is simple and intuitive, and ... -
Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We argue that full surface correspondence (registration) and optimal deformations (geodesics) are two related problems and propose a framework that solves them simultaneously. We build on the Riemannian shape analysis of ... -
Landscaper: A Modeling System for 3D Printing Scale Models of Landscapes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Landscape models of geospatial regions provide an intuitive mechanism for exploring complex geospatial information. However, the methods currently used to create these scale models require a large amount of resources, which ... -
Landscapes Synthesis Achieved through Erosion and Deposition Process Simulation
(Blackwell Science Ltd and the Eurographics Association, 1993)This paper describes an original approach to terrain evolution in landscapes synthesis. In order to create some realistic landforms, we simulate geologically contrasted terrains and apply to them deterministic erosion ... -
Langevin Particle: A Self-Adaptive Lagrangian Primitive for Flow Simulation Enhancement
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We develop a new Lagrangian primitive, named Langevin particle, to incorporate turbulent flow details in fluid simulation. A group of the particles are distributed inside the simulation domain based on a turbulence energy ... -
Language for Description of Geometric Configurations
(Blackwell Publishing Ltd and the Eurographics Association, 1990)This contribution is an informal presentation of some concepts, facts, and definitions about general configurations, as well as a description of our proposed GL/0 language for symbolic description of geometric configurations. ... -
Laplace–Beltrami Operator on Point Clouds Based on Anisotropic Voronoi Diagram
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)The symmetrizable and converged Laplace–Beltrami operator () is an indispensable tool for spectral geometrical analysis of point clouds. The , introduced by Liu et al. [LPG12] is guaranteed to be symmetrizable, but its ... -
Laplacian Colormaps: a Framework for Structure-preserving Color Transformations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Mappings between color spaces are ubiquitous in image processing problems such as gamut mapping, decolorization, and image optimization for color-blind people. Simple color transformations often result in information loss ... -
A Laplacian for Nonmanifold Triangle Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We describe a discrete Laplacian suitable for any triangle mesh, including those that are nonmanifold or nonorientable (with or without boundary). Our Laplacian is a robust drop-in replacement for the usual cotan matrix, ... -
Large and Small Eddies Matter: Animating Trees in Wind Using Coarse Fluid Simulation and Synthetic Turbulence
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Animating trees in wind has long been a problem in computer graphics. Progress on this problem is important for both visual effects in films and forestry biomechanics. More generally, progress on tree motion in wind may ... -
Large Scale Terrain Generation from Tectonic Uplift and Fluvial Erosion
(The Eurographics Association and John Wiley & Sons Ltd., 2016)At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. This paper presents the first method in ... -
Large-Scale Integer Linear Programming for Orientation Preserving 3D Shape Matching
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We study an algorithmic framework for computing an elastic orientation-preserving matching of non-rigid 3D shapes. We outline an Integer Linear Programming formulation whose relaxed version can be minimized globally in ... -
Large-Scale Worst-Case Topology Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We propose a novel topology optimization method to efficiently minimize the maximum compliance for a high-resolution model bearing uncertain external loads. Central to this approach is a modified power method that can ... -
