Data Painter: A Tool for Colormap Interaction
(The Eurographics Association, 2017)
The choice of a mapping from data to color should involve careful consideration in order to maximize the user understanding of the underlying data. It is desirable for features within the data to be visually separable and ...
Rendering and Extracting Extremal Features in 3D Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Visualizing and extracting three-dimensional features is important for many computational science applications, each with their own feature definitions and data types. While some are simple to state and implement (e.g. ...
Visualizing the Phase Space of Heterogeneous Inertial Particles in 2D Flows
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
In many scientific disciplines, the motion of finite-sized objects in fluid flows plays an important role, such as in brownout engineering, sediment transport, oceanology or meteorology. These finite-sized objects are ...
A General Illumination Model for Molecular Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Several visual representations have been developed over the years to visualize molecular structures, and to enable a better understanding of their underlying chemical processes. Today, the most frequently used atom-based ...
An Approximate Parallel Vectors Operator for Multiple Vector Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
The Parallel Vectors (PV) Operator extracts the locations of points where two vector fields are parallel. In general, these features are line structures. The PV operator has been used successfully for a variety of problems, ...
Analyzing Residue Surface Proximity to Interpret Molecular Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
The surface of a molecule holds important information about the interaction behavior with other molecules. In dynamic folding or docking processes, residues of amino acids with different properties change their position ...
Core Lines in 3D Second-Order Tensor Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Vortices are important features in vector fields that show a swirling behavior around a common core. The concept of a vortex core line describes the center of this swirling behavior. In this work, we examine the extension ...
Screen Space Particle Selection
(The Eurographics Association, 2018)
Analyses of large 3D particle datasets typically involve many different exploration and visualization steps. Interactive exploration techniques are essential to reveal and select interesting subsets like clusters or other ...
Gradient Field Estimation on Triangle Meshes
(The Eurographics Association, 2018)
The estimation of the differential properties of a function sampled at the vertices of a discrete domain is at the basis of many applied sciences. In this paper, we focus on the computation of function gradients on triangle ...
Adaptive Temporal Sampling for Volumetric Path Tracing of Medical Data
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Monte-Carlo path tracing techniques can generate stunning visualizations of medical volumetric data. In a clinical context, such renderings turned out to be valuable for communication, education, and diagnosis. Because a ...
