QEM-Filtering: A New Technique for Feature-Sensitive Terrain Mesh Simplification
(The Eurographics Association, 2010)Terrain simplification generates multi-resolution models, from which - traditionally - irregular or semi-regular triangulations are extracted to render a terrain at a suitable level of detail. Recent terrain simplification ... -
Quality Metrics for Information Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The visualization community has developed to date many intuitions and understandings of how to judge the quality of views in visualizing data. The computation of a visualization's quality and usefulness ranges from measuring ... -
Quality Metrics to Guide Visual Analysis of High Dimensional Genomics Data
(The Eurographics Association, 2020)Studies of genome sequenced data are increasingly common in many domains. Technological advances enable detection of hundreds of thousands of biological entities in samples, resulting in extremely high dimensional data. ... -
A Quality-Preserving Cartesian to Body-Centered Cubic Downsampling Transform
(The Eurographics Association, 2015)The body-centered cubic lattice is the optimal sampling lattice in three dimensions. However, most volumetric datasets are acquired on the well-known Cartesian cubic lattice. In order to leverage the approximation capabilities ... -
Quantifying Uncertainty in Multivariate Time Series Pre-Processing
(The Eurographics Association, 2019)In multivariate time series analysis, pre-processing is integral for enabling analysis, but inevitably introduces uncertainty into the data. Enabling the assessment of the uncertainty and allowing uncertainty-aware analysis, ... -
Quantifying Visual Abstraction ality for Stipple Drawings
(Association for Computing Machinery, Inc (ACM), 2017)We investigate how the perceived abstraction quality of stipple illustrations is related to the number of points used to create them. Since it is di cult to nd objective functions that quantify the visual quality of such ... -
Quantitative Analysis of Voxel Raytracing Acceleration Structures
(The Eurographics Association, 2014)In this work, we provide a comprehensive analysis of GPU acceleration structures for voxel raytracing. We compare the commonly used octrees to BVH and KD trees, which are the standard in GPU triangle raytracing. Evaluating ... -
A Quantitative Assessment of the Impact on Spatial Understanding of Exploring a Complex Immersive Virtual Environment using Augmented Real Walking versus Flying
(The Eurographics Association, 2007)When an immersive virtual environment spans an area that is larger than the available physical space for real walking, one may use an augmented walking method such as Seven League Boots to enable participants to explore ... -
Quantitative Comparison of Treemap Techniques for Time-Dependent Hierarchies
(The Eurographics Association, 2017)Hierarchical data in which leaf nodes have associated attributes appear in several applications. Rectangular Treemaps (RTs) were designed to display this type of data by tightly packing cells representing the tree nodes, ... -
Quantitative Evaluation for Edge Bundling Based on Structural Aesthetics
(The Eurographics Association, 2016)This study proposes a method to evaluate the efficiency of edge bundling. Edge bundling is important to improve visual clutter of edge visualization. However, the evaluation of edge bundling is based only on qualitative ... -
Quantitative Validation of Physically Based Deformable Models in Computer Graphics
(The Eurographics Association, 2018)This paper presents a novel software framework for quantitative validation of physically-based deformable models in computer graphics. In the majority of previous studies, validation is qualitative (through visual ... -
Quasi-3D cell-based Animation
(The Eurographics Association, 2003)We present a method for image compositing and rendering using 2D geometric shapes or raster images as input primitives, disposed in a 3D environment around which the camera can move. An animation system has been implemented ... -
Quaternion Fourier Transform for Character Motions
(The Eurographics Association, 2015)The Fourier transform plays a crucial role in a broad range of signal processing applications, including enhancement, restoration, analysis, and compression. Since animated motions comprise of signals, it is no surprise ... -
Query by Visual Words: Visual Search for Scatter Plot Visualizations
(The Eurographics Association, 2016)Finding interesting views in large collections of data visualizations, e.g., scatter plots, is challenging. Recently, ranking views based on heuristic quality measures has been proposed. However, quality measures may fail ... -
QuickSES: A Library for Fast Computation of Solvent Excluded Surfaces
(The Eurographics Association, 2019)Recently, several fast methods to compute Solvent Excluded Surfaces (SES) on GPUs have been presented. While these published methods reportedly yield interesting and useful results, up to now no public, freely accessible ... -
Random Sparse Coded Aperture for Lensless Imaging
(The Eurographics Association, 2014)This paper develops a computational lensless imaging system based on a random sparse coded aperture. The camera consists of a thin mask with a coded pattern and a standard sensor array. The proposed coded aperture contains ... -
RankASco: A Visual Analytics Approach to Leverage Attribute-Based User Preferences for Item Rankings
(The Eurographics Association, 2022)Item rankings are useful when a decision needs to be made, especially if there are multiple attributes to be considered. However, existing tools either do not support both categorical and numerical attributes, require ... -
RankBooster: Visual Analysis of Ranking Predictions
(The Eurographics Association, 2020)Ranking is a natural and ubiquitous way to facilitate decision-making in various applications. However, different rankings are often used for the same set of entities, with each ranking method placing emphasis on different ... -
Rapid Sketch-based 3D Modeling of Geology
(The Eurographics Association, 2013)We present and compare two different approaches for performing rapid 3D geological modeling. The ad-hoc approach is based on a composition of many specialized modeling functions, while the generic approach provides one ... -
