The goal is not the display of multiple data dimensions, but user comprehension of the multi-dimensional data. This paper explores several techniques for perceptually motivated procedural generation of shapes to increase the comprehension of multi-dimensional data. Our glyph-based system allows the visualization of both regular and irregular grids of volumetric data. A glyph's location, 3D size, color, and opacity encode up to 8 attributes of scalar data per glyph. We have extended the system's capabilities to explore shape variation as a visualization attribute. We use procedural shape generation techniques because they allow flexibility, data abstraction, and freedom from specification of detailed shapes. We have explored three procedural shape generation techniques: fractal detail generation, superquadrics, and implicit surfaces. These techniques allow from 1 to 14 additional data dimensions to be visualized using glyph shape.} } @InCollection{Herman:EGvissym99-SIV, crossref = {EGvissym99-proc}, author = {I. Herman and M. S.

How can we provide orientational cues so that a user can understand the location of the current viewpoint in a large data set?

The texture generator allows local control of orientation and length of the synthesized texture (the orientation and length of filaments). This texture model is then used to represent 2D vector fields. We can use orientation, length, density and color attributes of our furlike texture to visualize local orientation and magnitude of a 2D vector field. The visual representations produced are satisfying since complete information about local orientation is easily perceived. We will show that the technique can also produce LIC-like texture.

The task of the visualization system is to extract the features from all frames, to determine the correspondence between features in successive frames, and finally to visualize the tracking results. This paper describes a tracking system that uses feature data to solve the correspondence problem. It tracks feature paths and determines their evolution in time. The feature data consists of basic attributes such as position, size, and mas. For each set of attributes a number of correspondence functions can be tested which results in a correspondence factor. This factor makes it possible to quantify the goodness of the match between two features in successive time frames.

One of the culprits that introduce uncertainty in the visualization pipeline is the visualization algorithm itself. Uncertainties introduced this way usually arise from approximations and manifests themselves as artifacts in the resulting images. In this paper, we focus on comparing different direct volume rendering (DVR) algorithms and their artifacts as a result of DVR algorithm selections and their associated parameter settings. We present a new data level comparison methodology that uses differences in intermediate rendering information. In particular, we extend the traditional image level comparison techniques to include data level comparison techniques. In image level comparisons, quantized pixel values are the starting point for comparison measurements. In contrast, data level comparison techniques have the advantage of accessing and evaluating the intermediate 3D information during the rendering process. Our data level approach overcomes limitations of image level approaches and provide capabilities to compare application dependent details as well as general rendering qualities. One of the key challenges with our data level comparison approach is finding a common base for comparing the rich variety of DVR algorithms. In this paper, we present how a projection algorithm can be used as a base for comparing other DVR algorithms.In addition, a set of projection-based metrics are derived to quantify the comparison measurements among DVR algorithms. The results presented in this paper complement our earlier findings where a ray-based approach was used as the base for comparing other DVR algorithms.} } @InCollection{Udeshi:EGvissym99-PMP, crossref = {EGvissym99-proc}, author = {T.

This surface is subsequently rendered with an attached graphics hardware accelerator such as the SGI Infinite Reality. For even moderate data sets, Marching Cubes can generate an extraordinary number of polygons, which take time to construct and to render. As the isovalue is changed, the resulting surface, and perhaps the topology, is modified making display lists impractical. Current generation of high-end graphics adapters, such as the SGI Infinite Reality, have a quoted maximum polygon rendering rate of around 10M polygons/second. However, in practice this rate is difficult to achieve primarily due to geometry traversal (appropriate display list) and pixel coverage of the polygons. As a result, when viewing isosurfaces of large, greater than 1GByte, data sets rendering becomes a bottle neck. We have recently seen the attachment of multiple graphics adapters on high-end SGI Onyx2 supercomputers. The multiple graphics pipes can be used for multiple users or they can be combined to provide a single user the power of parallel rendering. Until recently, there has not been much experimentation with this configuration for polygon rendering. To address the rendering bottleneck, we have developed a multipipe strategy for parallel rendering using a combination of CPUs and parallel graphics adaptors. The multipipe system uses multiple graphics adapters in parallel, the so called {\em SGI Onyx2 Reality Monster}. In this paper, we discuss the issues of using the multiple pipes in a Sort-Last fashion which out performs a single graphics adaptor for a surprisingly low number of polygons.} } @InCollection{Clyne:EGvissym99-IDV, crossref = {EGvissym99-proc}, author = {J.

The usual way to compensate for the loss of spatial and occlusion information in MIP images is to view the data from different view points by rotating them.As the generation of MIP is usually non-interactive, this is done by calculating multiple images offline and playing them back as an animation. In this paper a new algorithm is proposed which is capable of interactively generating Maximum Intensity Projection images using parallel projection and templates. Voxels of the data set which will never contribute to a MIP due to their neighborhood are removed during a preprocessing step. The remaining voxels are stored in a way which guarantees optimal cache coherency regardless of the viewing direction. For use on low-end hardware, a preview-mode is included which renders only more significant parts of the volume during user interaction.

Information visualization makes it possible to exploit such historical data about past projects to help in the planning stages of future software projects.} } @InCollection{He:EGvissym99-IBF, crossref = {EGvissym99-proc}, author = {T.

This paper describes a web-based visualization tool on the basis of a kinematic simulation. The tool allows the visualization of the surface of an already ground workpiece as well as the changing shape of the workpiece during the grinding process. Two methods for the visualization of the grinding-objects are implemented. One method describes the scene with the Virtual Reality Modeling Language, the other one uses a renderer to create the images.} } @InCollection{Haase:EGvissym99-WWM, crossref = {EGvissym99-proc}, author = {H.

The brain shift is a brain deformation phenomenon, that occurs during surgical operations on the opened head. This deformation makes navigation within the brain very difficult for the surgeon, as preoperative magnetic resonance images invalidate very quickly after the beginning of the operation. Up to now not enough is known about this deformation phenomenon in order to come up with solutions for corrective action. The aim of the tool which is presented here is to prepare ground for a better understanding by visualizing the deformation between two 3D brain data sets, where one has been taken preoperatively and the second one during the operation after the brain shift has occured. We propose a new method for the modeling of the deformation by means of efficient distance determination of two deformable surface approximations. Color coding and semi-transparent overlay of the surfaces provides qualitative and quantitative information about the brain shift. The provided insight may lead to a prediction method in future.} } @InCollection{Walter:EGvissym99-AQC, crossref = {EGvissym99-proc}, author = {S. Walter and G. Stra{\ss{}}mann and M.

In financial data analysis, however, analysts still primarily rely on a set of statistical performance parameters in combination with traditional line charts in order to evaluate assets and to make decisions, and information visualization is only very slowly entering this important domain. In this paper, we analyze some of the standard statistical measures for technical financial data analysis and demonstrate cases where they produce insufficient and misleading results that do not reflect the real performance of an asset. We propose a technique for visualizing financial time series data that eliminates these inadequacies, offering a complete view on the real performance of an asset. The technique is enhanced by relevance and weighting functions according to the users' preferences in order to emphasize specific regions of interest. Based on these principles we redefine some of the standard performance measures. We apply our technique on real world financial data sets and combine it with higher-level financial analysis techniques such as performance/risk analysis, dominance evaluation, and efficiency curves in order to show how traditional techniques from economics can be improved by modern visual data analysis techniques.} } @inproceedings{EuroVis07:27-34:2007, crossref = {EuroVis07-proc}, author = {Ming Hao and Umeshwar Dayal and Daniel Keim and Tobias Schreck}, title = {{Multi-Resolution Techniques for Visual Exploration of Large Time-Series Data }}, pages = {27-34}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/027-034.pdf}, DOI = {10.2312/VisSym/EuroVis07/027-034}, abstract = {Time series are a data type of utmost importance in many domains such as business management and service monitoring. We address the problem of visualizing large time-related data sets which are difficult to visualize effectively with standard techniques given the limitations of current display devices. We propose a framework for intelligent time- and data-dependent visual aggregation of data along multiple resolution levels. This idea leads to effective visualization support for long time-series data providing both focus and context. The basic idea of the technique is that either data-dependent or application-dependent, display space is allocated in proportion to the degree of interest of data subintervals, thereby (a) guiding the user in perceiving important information, and (b) freeing required display space to visualize all the data. The automatic part of the framework can accommodate any time series analysis algorithm yielding a numeric degree of interest scale. We apply our techniques on real-world data sets, compare it with the standard visualization approach, and conclude the usefulness and scalability of the approach.} } @inproceedings{EuroVis07:35-42:2007, crossref = {EuroVis07-proc}, author = {Jimmy Johansson and Patric Ljung and Matthew Cooper}, title = {{Depth Cues and Density in Temporal Parallel Coordinates }}, pages = {35-42}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/035-042.pdf}, DOI = {10.2312/VisSym/EuroVis07/035-042}, abstract = {This paper introduces Temporal Density Parallel Coordinates (TDPC) and Depth Cue Parallel Coordinates (DCPC) which extend the standard 2D parallel coordinates technique to capture time-varying dynamics. The proposed techniques can be used to analyse temporal positions of data items as well as temporal positions of changes occurring using 2D displays. To represent temporal changes, polygons (instead of traditional lines) are rendered in parallel coordinates. The results presented show that rendering polygons is superior at revealing large temporal changes. Both TDPC and DCPC have been efficiently implemented on the GPU allowing the visualization of thousands of data items over thousands of time steps at interactive frame rates.} } @inproceedings{EuroVis07:43-50:2007, crossref = {EuroVis07-proc}, author = {Petra Neumann and Annie Tat and Torre Zuk and Sheelagh Carpendale}, title = {{KeyStrokes: Personalizing Typed Text with Visualization }}, pages = {43-50}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/043-050.pdf}, DOI = {10.2312/VisSym/EuroVis07/043-050}, abstract = {With the ubiquity of typed text, the style and much of the personality of handwriting has been lost from general communication.

Through case studies we show how our visualization uses a hybrid layout along with varying transparency, colour, and size to reveal the lattice structure, expose the inherent uncertainty in statistical processing, and help users make better-informed decisions about statistically-derived outputs.} } @inproceedings{EuroVis07:59-66:2007, crossref = {EuroVis07-proc}, author = {Christian Heine and Gerik Scheuermann}, title = {{Manual Clustering Refinement using Interaction with Blobs }}, pages = {59-66}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/059-066.pdf}, DOI = {10.2312/VisSym/EuroVis07/059-066}, abstract = {The huge amount of different automatic clustering methods emphasizes one thing: there is no optimal clustering method for all possible cases. In certain application domains, like genomics and natural language processing, it is not even clear if any of the already known clustering methods suffice. In such cases, an automatic clustering method is often followed by manual refinement. The refined version may then be used as either an illustration, a reference, or even an input for a rule based or other machine learning algorithm as a new clustering method. In this paper, we describe a novel interaction technique to manual cluster refinement using the metaphor of soap bubbles, represented by special implicit surfaces (blobs). For instance, entities can simply be moved inside and outside of these blobs. A modified force-directed layout process automatically arranges entities equidistant on the screen. The modifications include a reduction to the expected amount of computation per iteration down to O(|V| log |V|+|E|) in order to achieve a high response time for use in an interactive system. We also spend a considerable amount of effort making the display of blobs fast enough for an interactive system.} } @inproceedings{EuroVis07:67-74:2007, crossref = {EuroVis07-proc}, author = {Daniel Archambault and Tamara Munzner and David Auber}, title = {{Grouse: Feature-Based, Steerable Graph Hierarchy Exploration }}, pages = {67-74}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/067-074.pdf}, DOI = {10.2312/VisSym/EuroVis07/067-074}, abstract = {Grouse is a feature-based approach to steerable exploration of a graph and an associated hierarchy.

Grouse preserves the input hierarchy, which provides meaningful information to the user when its metanodes correspond to features of interest. When a metanode in the hierarchy is opened, a limited number of metanodes are laid out again along the path between the opened node and the root. We demonstrate the effectiveness of Grouse on datasets from IMDB, the Internet Movie Database, where nodes are actors and cliques represent movies. The combination of feature-based layout and limited relayout computation does not fragment features in the hierarchy and improves the number of levels in the hierarchy that can be seen at once over previous approaches.} } @inproceedings{EuroVis07:75-82:2007, crossref = {EuroVis07-proc}, author = {Yaniv Frishman and Ayellet Tal}, title = {{Online Dynamic Graph Drawing }}, pages = {75-82}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/075-082.pdf}, DOI = {10.2312/VisSym/EuroVis07/075-082}, abstract = {This paper presents an algorithm for drawing a sequence of graphs online.

The interface consists of three components which abstracts the complexity of exploring in temporal, variable, and spatial domain, respectively. The first component displays time histograms of the data, helps the user identify timesteps of interest, and also helps specify time-varying features. The second component displays correlations between variables in parallel coordinates and enables the user to verify those correlations and possibly identity unanticipated ones. The third component allows the user to more closely explore and validate the data in spatial domain while rendering multiple variables into a single visualization in a user controllable fashion. Each of these three components is not only an interface but is also the visualization itself, thus enabling efficient screen-space usage. The three components are tightly linked to facilitate tri-space data exploration, which offers scientists new power to study their time-varying, multivariate volume data.} } @inproceedings{EuroVis07:123-130:2007, crossref = {EuroVis07-proc}, author = {Jorik Blaas and Charl P.

Images can then be generated via tetrahedral projection or raycasting. A current shortcoming in VS-based operations is the need for a very high level of subdivision to represent fine detail in the mesh and to obtain a high-fidelity visualization. However, we have discovered that the subdivision process itself can be closely simulated with radial basis functions (RBFs), making it possible to replace the finer subdivision levels by a coarser aggregation of RBF kernels. This reduction to a simplified assembly of RBFs subsequently enables interactive rendering of volumetric subdivision shapes within a GPU-based volume splatting framework.} } @inproceedings{EuroVis07:147-154:2007, crossref = {EuroVis07-proc}, author = {Markus Schedl and Peter Knees and Klaus Seyerlehner and Tim Pohle}, title = {{The CoMIRVA Toolkit for Visualizing Music-Related Data }}, pages = {147-154}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/147-154.pdf}, DOI = {10.2312/VisSym/EuroVis07/147-154}, abstract = {We present CoMIRVA, which is an abbreviation for Collection of Music Information Retrieval and Visualization Applications.

Principal component analysis (PCA) is used to decompose the datacube into several discriminating components. We represent these extracted features as abstract geometric shapes and use three parameters to allow for data exploration. The first parameter thresholds the spectral contribution at which an extracted component is visualized. The level of detail the shapes is controlled by a second parameter and a third parameter determines at which density-level the extracted feature is represented. This new visualization technique enables an analyst to select the most relevant spectral correlations and investigate their specific spatial distribution.

The proposed techniques are used in the visual analysis of the Terashake 2.1 earthquake simulation data, and they have been shown to be very effective in revealing the relevant information in this data.} } @inproceedings{EuroVis07:259-266:2007, crossref = {EuroVis07-proc}, author = {Michael ten Caat and Natasha M.

A measure for this synchrony is electroencephalography (EEG) coherence, computed between pairs of signals as a function of frequency. Existing high-density EEG coherence visualizations are generally either hypothesis-driven, or data-driven graph visualizations which are cluttered. In this paper, a new method is presented for data-driven visualization of high-density EEG coherence, which strongly reduces clutter and is referred to as functional unit (FU) map. Starting from an initial graph, with vertices representing electrodes and edges representing significant coherences between electrode signals, we define an FU as a set of electrodes represented by a clique consisting of spatially connected vertices. In an FU map, the spatial relationship between electrodes is preserved, and all electrodes in one FU are assigned an identical gray value. Adjacent FUs are visualized with different gray values and FUs are connected by a line if the average coherence between FUs exceeds a threshold. Results obtained with our visualization are in accordance with known electrophysiological findings. FU maps can be used as a preprocessing step for conventional analysis.} } @inproceedings{EuroVis07:267-274:2007, crossref = {EuroVis07-proc}, author = {Konrad Muehler and Mathias Neugebauer and Christian Tietjen and Bernhard Preim}, title = {{Viewpoint Selection for Intervention Planning }}, pages = {267-274}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/267-274.pdf}, DOI = {10.2312/VisSym/EuroVis07/267-274}, abstract = {Viewpoint selection is crucial for medical intervention planning. The interactive exploration of a scene with 3d objects involves the systematic analysis of several anatomic structures. Viewpoint selection techniques enhance the display of the currently selected structure. For animations in collaborative intervention planning and surgical education, the authoring process may be significantly enhanced if ?good' viewpoints for important objects as well as for the whole scene are chosen automatically.We describe a viewpoint selection technique guided by parameters like size of unoccluded surface, importance of occluding objects, preferred region and viewpoint stability. The influence of these parameters may be flexibly adjusted by weights. Parameter maps indicate the influence of the current parameter settings on the viewpoints. For selected applications, the weights may be predefined and reused for other cases. We also describe an informal user study which was accomplished to understand if our viewpoint selection strategies produce adequate results from the users' point of view.} } @inproceedings{EuroVis07:275-282:2007, crossref = {EuroVis07-proc}, author = {Michael Burns and Martin Haidacher and Wolfgang Wein and Ivan Viola and Eduard Groeller}, title = {{Feature Emphasis and Contextual Cutaways for Multimodal Medical Visualization }}, pages = {275-282}, URL = {http://www.eg.org/EG/DL/WS/VisSym/EuroVis07/275-282.pdf}, DOI = {10.2312/VisSym/EuroVis07/275-282}, abstract = {Dense clinical data like 3D Computed Tomography (CT) scans can be visualized together with real-time imaging for a number of medical intervention applications. However, it is difficult to provide a fused visualization that allows sufficient spatial perception of the anatomy of interest, as derived from the rich pre-operative scan, while not occluding the real-time image displayed embedded within the volume. We propose an importance-driven approach that presents the embedded data such that it is clearly visible along with its spatial relation to the surrounding volumetric material. To support this, we present and integrate novel techniques for importance specification, feature emphasis, and contextual cutaway generation. We show results in a clinical context where a pre-operative CT scan is visualized alongside a tracked ultrasound image, such that the important vasculature is depicted between the viewpoint and the ultrasound image, while a more opaque representation of the anatomy is exposed in the surrounding area.} } @inproceedings{EuroVis07:283-290:2007, crossref = {EuroVis07-proc}, author = {Christian Schumann and Steffen Oeltze and Ragnar Bade and Bernhard Preim and H.- O.

A variety of techniques has been developed which provide smooth high-quality visualizations of vascular structures based on rather simple model assumptions. For diagnostic applications, these model assumptions and the resulting deviations from the actual vessel surface are not acceptable. We present a model-free approach which employs the binary result of a prior vessel segmentation as input. Instead of directly converting the segmentation result into a surface, we compute a point cloud which is adaptively refined at thin structures, where aliasing effects are particularly obvious and artifacts may occur. The point cloud is transformed into a surface representation by means of MPU Implicits, which provide a smooth piecewise quadratic approximation. Our method has been applied to a variety of datasets including pathologic cases. The generated visualizations are considerably more accurate than model-based approaches. Compared to other model-free approaches, our method produces smoother results.} } @proceedings{EuroVis07-proc, editor = {K. Museth and T. M{\"o}ller and A.
