Approximate Symmetry Detection in Partial 3D Meshes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Symmetry is a common characteristic in natural and man-made objects. Its ubiquitous nature can be exploited to facilitate the analysis and processing of computational representations of real objects. In particular, in ... -
Interactive Image-Guided Modeling of Extruded Shapes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)A recent trend in interactive modeling of 3D shapes from a single image is designing minimal interfaces, and accompanying algorithms, for modeling a specific class of objects. Expanding upon the range of shapes that existing ... -
Multiple Shape Correspondence by Dynamic Programming
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a multiple shape correspondence method based on dynamic programming, that computes consistent bijective maps between all shape pairs in a given collection of initially unmatched shapes. As a fundamental distinction ... -
Anisotropic Geodesics for Live-wire Mesh Segmentation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an interactive method for mesh segmentation that is inspired by the classical live-wire interaction for image segmentation. The core contribution of the work is the definition and computation of wires on surfaces ... -
Structure Aware Visual Cryptography
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Visual cryptography is an encryption technique that hides a secret image by distributing it between some shared images made up of seemingly random black-and-white pixels. Extended visual cryptography (EVC) goes further in ... -
Polyline-sourced Geodesic Voronoi Diagrams on Triangle Meshes
(The Eurographics Association and John Wiley and Sons Ltd., 2014) -
Hybrid Particle-grid Modeling for Multi-scale Droplet/Spray Simulation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a novel hybrid particle-grid method that tightly couples Lagrangian particle approach with Eulerian grid approach to simulate multi-scale diffuse materials varying from disperse droplets to dissipating ... -
Advanced Hybrid Particle-Grid Method with Sub-Grid Particle Correction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper proposes a novel hybrid particle-grid approach to liquid simulation, which uses the fluid-implicitparticle (FLIP) method to resolve the liquid motion and a grid-based particle correction method to complement ... -
G2 Surface Interpolation Over General Topology Curve Networks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The basic idea of curve network-based design is to construct smoothly connected surface patches, that interpolate boundaries and cross-derivatives extracted from the curve network. While the majority of applications demands ... -
Adaptive Multi-scale Analysis for Point-based Surface Editing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a tool that enables the direct editing of surface features in large point-clouds or meshes. This is made possible by a novel multi-scale analysis of unstructured point-clouds that automatically extracts ... -
shade.js: Adaptive Material Descriptions
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In computer graphics a material is a visual concept that is parameterizable and should work for arbitrary 3D assets and rendering systems. Since provided parameters and attributes as well as the capabilities of rendering ... -
Sub-Pixel Anti-Aliasing Via Triangle-Based Geometry Reconstruction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Anti-aliasing has recently been employed as a post-processing step to adapt to the deferred shading technique in real-time applications. Some of these existing algorithms store supersampling geometric information as geometric ... -
Editing and Synthesizing Two-Character Motions using a Coupled Inverted Pendulum Model
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This study aims to develop a controller for use in the online simulation of two interacting characters. This controller is capable of generalizing two sets of interaction motions of the two characters based on the relationships ... -
Sky Based Light Metering for High Dynamic Range Images
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Image calibration requires both linearization of pixel values and scaling so that values in the image correspond to real-world luminances. In this paper we focus on the latter and rather than rely on camera characterization, ... -
Using Physically Based Rendering to Benchmark Structured Light Scanners
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Structured light scanning is ubiquituous in 3D acquisition. It is capable of capturing high geometric detail at a low cost under a variety of challenging scene conditions. Recent methods have demonstrated robustness in the ... -
Environment-Adaptive Contact Poses for Virtual Characters
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel method to generate a virtual character's multi-contact poses adaptive to the various shapes of the environment. Given the user-specified center of mass (CoM) position and direction as inputs, our method ... -
Locomotion Skills for Insects with Sample-based Controller
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Natural-looking insect animation is very difficult to simulate. The fast movement and small scale of insects often challenge the standard motion capture techniques. As for the manual key-framing or physics-driven methods, ... -
Template-Based Sampling of Anisotropic BRDFs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)BRDFs are commonly used to represent given materials' appearance in computer graphics and related fields. Although, in the recent past, BRDFs have been extensively measured, compressed, and fitted by a variety of ana- ... -
