Extraction and Visual Analysis of Seismic Horizon Ensembles
(The Eurographics Association, 2013)Seismic interpretation is an important step in building subsurface models, which are needed to efficiently exploit fossil fuel reservoirs. However, seismic features are seldom unambiguous, resulting in a high degree of ... -
Extraction of Crack-free Isosurfaces from Adaptive Mesh Refinement Data
(The Eurographics Association, 2001)Adaptive mesh refinement (AMR) is a numerical simulation technique used in computational fluid dynamics (CFD). It permits the efficient simulation of phenomena characterized by substantially varying scales in complexity ... -
Extraction of Critical Points and Nets Based on Discrete Gradient Vector Field
(Eurographics Association, 2002)In this paper we address the problem of representing the topology of discrete scalar fields defined on triangulated domains. To this aim, we use the notion of discrete gradient vector field that we have introduced in [4] ... -
Extraction of Distinguished Hyperbolic Trajectories for 2D Time-Dependent Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2020)This paper does two main contributions to 2D time-dependent vector field topology. First, we present a technique for robust, accurate, and efficient extraction of distinguished hyperbolic trajectories (DHT), the generative ... -
Extraction of Dominant Extremal Structures in Volumetric Data Using Separatrix Persistence
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Extremal lines and surfaces are features of a 3D scalar field where the scalar function becomes minimal or maximal with respect to a local neighborhood -
Extraction Of Feature Lines On Surface Meshes Based On Discrete Morse Theory
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We present an approach for extracting extremal feature lines of scalar indicators on surface meshes, based on discrete Morse Theory. By computing initial Morse-Smale complexes of the scalar indicators of the mesh, we obtain ... -
Extraction of Robust Voids and Pockets in Proteins
(The Eurographics Association, 2013)Voids and pockets in a protein refer to empty spaces that are enclosed by the protein molecule. Existing methods to compute, measure, and visualize the voids and pockets in a protein molecule are sensitive to inaccuracies ... -
Extraction of Typographic Elements from Outline Representations of Fonts
(Blackwell Science Ltd and the Eurographics Association, 1996)Digital typefaces for computer graphics and multimedia applications should be capable of supporting operations such as font variations, transformations. deformations and blending. A powerful implementation of such operations ... -
Extração de informação de texto formal para a modelação expedita de edifícios monumentais
(The Eurographics Association, 2021)A extração de informação a partir de descrições textuais para a modelação procedimental de ambientes urbanos é apresentada com solução para os edifícios antigos. No entanto, este tipo de edifício carece de maior cuidado ... -
Extrapolating Large-Scale Material BTFs under Cross-Device Constraints
(The Eurographics Association, 2015)In this paper, we address the problem of acquiring bidirectional texture functions (BTFs) of large-scale material samples. Our approach fuses gonioreflectometric measurements of small samples with few constraint images ... -
Extreme Feature Regions for Image Matching
(The Eurographics Association, 2018)Extreme feature regions are increasingly critical for many image matching applications on affine image-pairs. In this paper, we focus on the time-consumption and accuracy of using extreme feature regions to do the ... -
Extreme Model Simplification for Forest Rendering
(The Eurographics Association, 2005)Models of large forest scenes are of a geometric complexity that surpasses even the capabilities of current high end graphics hardware. We propose an extreme simplification method which allows us to render such scenes in ... -
Extrinsic Self-Calibration of Time-of-Flight Cameras using a Combination of 3D and Intensity Descriptors
(The Eurographics Association, 2011)Time-of-Flight (ToF) cameras are able to simultaneously record intensity and depth images at a high frequency. Many applications require images that are recorded from different viewpoints. In order to consolidate the ... -
An Eye Gaze Model for Dyadic Interaction in an Immersive Virtual Environment: Practice and Experience
(The Eurographics Association and Blackwell Publishing Ltd., 2004)This paper describes a behavioural model used to simulate realistic eye-gaze behaviour and body animations for avatars representing participants in a shared immersive virtual environment (IVE). The model was used in a study ... -
An Eye on Perceptual Graphics: Eye-Tracking Methodology
(The Eurographics Association, 2013)Eye-tracking technology has evolved considerably over the last decade. The tutorial provides attendees with stateof- the-art advancements and their relevance to computer graphics research, one of the most important being ... -
Eye Reconstruction and Modeling for Digital Humans
(2018)The creation of digital humans is a long-standing challenge of computer graphics. Digital humans are tremendously important for applications in visual effects and virtual reality. The traditional way to generate digital ... -
Eye Tracking Visualization
(The Eurographics Association, 2015)Eye tracking has become a widely used method to analyze user behavior in marketing, neuroscience, human-computer interaction, and visualization research. Apart from measuring completion times and recording accuracy rates ... -
Eye-Centered Color Adaptation in Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Color adaptation is a well known ability of the human visual system (HVS). Colors are perceived as constant even though the illuminant color changes. Indeed, the perceived color of a diffuse white sheet of paper is still ... -
An Eye-Tracking Study on Sparklines within Textual Context
(The Eurographics Association, 2018)Sparklines are placed in documents but their usability is rarely evaluated in their immediate context of paragraphs of text. We conducted an eye-tracking study to measure readability and understandability of four different ... -
