Molecular visualizations are a principal tool for analyzing the results of biochemical simulations With modern GPU ray casting approaches it is only possible to render several millions of atoms at interactive frame rates unless advanced acceleration methods are employed But even simplified cell models of whole-cell simulations consist of at least several b

Rigid adherence to pre-specified thresholds and static graphical representations can lead to incorrect decisions on merging of clusters As an alternative to existing automated or semi-automated methods, we developed a visual analytics approach for performing hierarchical clustering analysis of short time-series gene expression data Dynamic sliders control
The interaction of three-dimensional linked hydrophilic polymers with surrounding solvents in time-dependent data sets is of great interest for domain experts and current research in molecular dynamics These polymers are called hydrogels, and their most characteristic property is their swelling in aqueous solutions by absorbing the solvent Their conformati
Arguments are structures of premises and conclusions that underpin rational reasoning processes Within complex knowledge domains, especially if they are contentious, argument structures can become large and complex Visualization tools have been developed that support argument analysts and help them to work with arguments Until recently, arguments were man
Choosing a single similarity threshold for cutting dendrograms is not sufficient for performing hierarchical clustering analysis of heterogeneous data sets In addition, alternative automated or semi-automated methods that cut dendrograms in multiple levels make assumptions about the data in hand In an attempt to help the user to find patterns in the data a
In this paper, we discuss the reproducibility of our work presented at EuroVis 2014 [LKEP14], which describes an illustrative rendering method tailored to molecular surfacesWe distinguish between the reproducibility of the data sets that were used for figures and performance analysis and the reproducibility in the sense of re-implementing the method For th
In this paper we present a technique for interactively rendering transparent molecular surfaces We use Puxels, our implementation of per-pixel linked lists for order-independent transparency rendering Furthermore, we evaluate the usage of per-pixel arrays as an alternative for this rendering technique We describe our real-time rendering technique for tran
Structural properties of molecules are of primary concern in many fields This report provides a comprehensive overview on techniques that have been developed in the fields of molecular graphics and visualization with a focus on applications in structural biology The field heavily relies on computerized geometric and visual representations of three-dimensio
Forensic case analysis and in court presentation requires comprehensible illustrations and animations of findings and their relations to the course of events Often this can only be achieved by adding textual descriptions From a systems point of view, this requires automated label placement functionality for scenes composed of translucent polyhedral models
Passive eye-pose estimation methods that recover the eye-pose from natural images generally suffer from low accuracy, the result of a static eye model, and the recovery of the eye model from the estimated iris contour Active eye-pose estimation methods use precisely calibrated light sources to estimate a user specific eye-model These methods recover an acc
In this paper, we show how to capture an actor with no intrusive trackers and without any special environment like blue set, how to estimate its 3D-geometry and how to insert this geometry into a virtual world in real-time We use several cameras in conjunction with background subtraction to produce silhouettes of the actor as observed from the different cam

Recent large-scale particle-based simulations are generating vast amounts of data posing a challenge to visualization algorithms One possibility for addressing this challenge is to map particles into a regular grid for volume rendering, which carries the disadvantages of inefficient use of memory and undesired losses of dynamic range As an alternative, we

Heritage sites (such as prehistoric burial cairns and standing stones) are prolific in Europe; although there is a wish to scan each of these sites, it would be time-consuming to achieve Citizen science approaches enable us to involve the public to perform a metric survey by capturing images In this paper, discussing work-in progress, we present our automa
