General Point Sampling with Adaptive Density and Correlations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ... -
Generalized Matryoshka: Computational Design of Nesting Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper generalizes the self-similar nesting of Matryoshka dolls (''Russian nesting dolls'') to arbitrary solid objects. We introduce the problem of finding the largest scale replica of an object that nests inside itself. ... -
Generating Tile Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Tile maps are an important tool in thematic cartography with distinct qualities (and limitations) that distinguish them from better-known techniques such as choropleths, cartograms and symbol maps. Specifically, tile maps ... -
Geometric Detection Algorithms for Cavities on Protein Surfaces in Molecular Graphics: A Survey
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)Detecting and analysing protein cavities provides significant information about active sites for biological processes (e.g. protein–protein or protein–ligand binding) in molecular graphics and modelling. Using the ... -
Geometric Stiffness for Real-time Constrained Multibody Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper focuses on the stable and efficient simulation of articulated rigid body systems for real-time applications. Specifically, we focus on the use of geometric stiffness, which can dramatically increase simulation ... -
Global Feature Tracking and Similarity Estimation in Time-Dependent Scalar Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present an algorithm for tracking regions in time-dependent scalar fields that uses global knowledge from all time steps for determining the tracks. The regions are defined using merge trees, thereby representing a ... -
Glyph-Based Comparative Stress Tensor Visualization in Cerebral Aneurysms
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present the first visualization tool that enables a comparative depiction of structural stress tensor data for vessel walls of cerebral aneurysms. Such aneurysms bear the risk of rupture, whereas their treatment also ... -
GPU Ray Tracing using Irregular Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present a spatial index structure to accelerate ray tracing on GPUs. It is a flat, non-hierarchical spatial subdivision of the scene into axis aligned cells of varying size. In order to construct it, we first nest an ... -
A GPU-Adapted Structure for Unstructured Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)A key advantage of working with structured grids (e.g., images) is the ability to directly tap into the powerful machinery of linear algebra. This is not much so for unstructured grids where intermediate bookkeeping data ... -
Gradient-based Steering for Vision-based Crowd Simulation Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Most recent crowd simulation algorithms equip agents with a synthetic vision component for steering. They offer promising perspectives through a more realistic simulation of the way humans navigate according to their ... -
Gradient-Domain Photon Density Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The most common solutions to the light transport problem rely on either Monte Carlo (MC) integration or density estimation methods, such as uni- & bi-directional path tracing or photon mapping. Recent gradient-domain ... -
Graffinity: Visualizing Connectivity in Large Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Multivariate graphs are prolific across many fields, including transportation and neuroscience. A key task in graph analysis is the exploration of connectivity, to, for example, analyze how signals flow through neurons, ... -
Graph Layouts by t-SNE
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose a new graph layout method based on a modification of the t-distributed Stochastic Neighbor Embedding (t-SNE) dimensionality reduction technique. Although t-SNE is one of the best techniques for visualizing ... -
Graphs in Scientific Visualization: A Survey
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)Graphs represent general node‐link diagrams and have long been utilized in scientific visualization for data organization and management. However, using graphs as a visual representation and interface for navigating and ... -
GraSp: Combining Spatially-aware Mobile Devices and a Display Wall for Graph Visualization and Interaction
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Going beyond established desktop interfaces, researchers have begun re-thinking visualization approaches to make use of alternative display environments and more natural interaction modalities. In this paper, we investigate ... -
Group Modeling: A Unified Velocity‐Based Approach
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)Crowd simulators are commonly used to populate movie or game scenes in the entertainment industry. Even though it is crucial to consider the presence of groups for the believability of a virtual crowd, most crowd simulations ... -
Group Representation of Global Intrinsic Symmetries
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Global intrinsic symmetry detection of 3D shapes has received considerable attentions in recent years. However, unlike extrinsic symmetry that can be represented compactly as a combination of an orthogonal matrix and a ... -
Group-Theme Recoloring for Multi-Image Color Consistency
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Modifying the colors of an image is a fundamental editing task with a wide range of methods available. Manipulating multiple images to share similar colors is more challenging, with limited tools available. Methods such ... -
