Hardware-accelerated Extraction and Rendering of Point Set Surfaces
(The Eurographics Association, 2006)Point-based models are gaining lately considerable attention as an alternative to traditional surface meshes. In this context, Point Set Surfaces (PSS) were proposed as a modeling and rendering method with important ... -
A Granular Three Dimensional Multiresolution Transform
(The Eurographics Association, 2006)We propose a three dimensional multi-resolution scheme to represent volumetric data in resolutions which are powers of two, resolving the rigidity of the commonly used separable Cartesian multi-resolution schemes in 3D ... -
Perspective Isosurface and Direct Volume Rendering for Virtual Endoscopy Applications
(The Eurographics Association, 2006)Virtual endoscopy has proven to be a very powerful tool in endoscopic surgery. However, most virtual endoscopy systems are restricted to rendering isosurfaces or require segmentation in order to visualize additional objects ... -
Affiliation Dynamics with an Application to Movie-Actor Biographies
(The Eurographics Association, 2006)We propose a visualization approach for dynamic affiliation networks in which events are characterized by a set of descriptors. It uses a radial ripple metaphor to display the passing of time and conveys relations among ... -
Visualizing the Phonon Map
(The Eurographics Association, 2006)In this work we present several visualization approaches for analyzing acoustic behavior inside a room. Our methods are based on the results of the phonon tracing algorithm. For a simulated phonon map we examine the influence ... -
Lossless Geometry Compression for Steady-State and Time-Varying Irregular Grids
(The Eurographics Association, 2006)In this paper we investigate the problem of lossless geometry compression of irregular-grid volume data represented as a tetrahedral mesh. We propose a novel lossless compression technique that effectively predicts, models, ... -
GPU-Accelerated Volume Splatting With Elliptical RBFs
(The Eurographics Association, 2006)Radial Basis Functions (RBFs) have become a popular rendering primitive, both in surface and in volume rendering. This paper focuses on volume visualization, giving rise to 3D kernels. RBFs are especially convenient for ... -
Direct Isosurface Extraction from Scattered Volume Data
(The Eurographics Association, 2006)Isosurface extraction is a standard visualization method for scalar volume data and has been subject to research for decades. Nevertheless, to our knowledge, no isosurface extraction method exists that directly extracts ... -
Efficient Surface Reconstruction from Noisy Data using Regularized Membrane Potentials
(The Eurographics Association, 2006)We present a novel, physically-motivated method for surface reconstruction that can recover smooth surfaces from noisy and sparse data sets, without using orientation information. A new volumetric technique based on ... -
Volume Composition Using Eye Tracking Data
(The Eurographics Association, 2006)This paper presents a method to automate rendering parameter selection, simplifying tedious user interaction and improving the usability of visualization systems. Our approach acquires regions-of-interest for a dataset ... -
Knowledge-Based Out-of-Core Algorithms for Data Management in Visualization
(The Eurographics Association, 2006)Data management is the very first issue in handling very large datasets. Many existing out-of-core algorithms used in visualization are closely coupled with application-specific logic. This paper presents two knowledgebased ... -
GPU-Based Hyperstreamlines for Diffusion Tensor Imaging
(The Eurographics Association, 2006)We propose a new approach for the visualization of hyperstreamlines, which offers potential for better scalability than the conventional polygon-based approach. Our method circumvents the bandwidth bottleneck between the ... -
Enhancing Slice-based Visualizations of Medical Volume Data
(The Eurographics Association, 2006)Slice-based visualizations of CT and MRI data are frequently used for diagnosis, intervention planning and intraoperative navigation since they allow a precise analysis and localization. We present new techniques to enhance ... -
Combining Extended Table Lens and Treemap Techniques for Visualizing Tabular Data
(The Eurographics Association, 2006)We present a framework for visualizing large tabular data that combines two views: the table view and the treemap view. The table view extends the known table lens as follows: We cluster related elements to reduce subsampling ... -
Evaluating the Effectiveness of Tree Visualization Systems for Knowledge Discovery
(The Eurographics Association, 2006)User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the ... -
Terrain Rendering using Spherical Clipmaps
(The Eurographics Association, 2006)We describe a terrain rendering algorithm for spherical terrains based on clipmaps. It leverages the high geometry throughput of current GPU to render large static triangle sets. The vertices are displaced by a height map ... -
Robust Surface Detection for Variance Comparison and Dimensional Measurement
(The Eurographics Association, 2006)This paper describes a robust method for creating surface models from volume datasets with distorted density values due to artefacts and noise. Application scenario for the presented work is variance comparison and dimensional ... -
