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 ... -
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 ... -
GPUFLIC: Interactive and Accurate Dense Visualization of Unsteady Flows
(The Eurographics Association, 2006)The paper presents an efficient and accurate implementation of Unsteady Flow LIC (UFLIC) on the Graphics Processing Unit (GPU). We obtain the same, high quality texture representation of unsteady two-dimensional flows as ... -
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 ... -
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 ... -
Improving the Quality of Multi-resolution Volume Rendering
(The Eurographics Association, 2006)We propose a novel method to improve the quality of multi-resolution visualizations. We reduce aliasing artifacts by approximating the data distribution with a Gaussian basis function at each level of detail for more ... -
Integrated Visualization of Morphologic and Perfusion Data for the Analysis of Coronary Artery Disease
(The Eurographics Association, 2006)We present static and dynamic techniques to visualize perfusion data and to relate perfusion data to morphologic image data. In particular, we describe the integrated analysis of MRI myocardial perfusion data with CT ... -
Integrating Dynamic Deformations into Interactive Volume Visualization
(The Eurographics Association, 2006)Non-linear geometric deformation (or warping) is a useful tool for working with volumes. Unfortunately, the computational expense of performing the resampling needed to implement volume deformation has precluded its use ... -
An Interactive Visualization System for Quantifying Coral Structures
(The Eurographics Association, 2006)Determining the shape of coral structures is an essential step for coral biologists to classify and compare corals. Currently, coral biologists analyze shape by performing manual measurements on photographs of coral colonies. ... -
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 ... -
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, ... -
Multiresolution Interblock Interpolation in Direct Volume Rendering
(The Eurographics Association, 2006)We present a direct interblock interpolation technique that enables direct volume rendering of blocked, multiresolution volumes. The proposed method smoothly interpolates between blocks of arbitrary block-wise level-of-detail ... -
Natural Visualizations
(The Eurographics Association, 2006)This paper demonstrates the prevalence of a shared characteristic between visualizations and images of nature. We have analyzed visualization competitions and user studies of visualizations and found that the more preferred, ... -
Path Line Oriented Topology for Periodic 2D Time-Dependent Vector Fields
(The Eurographics Association, 2006)This paper presents an approach to extracting a path line oriented topological segmentation for periodic 2D timedependent vector fields. Topological methods aiming in capturing the asymptotic behavior of path lines rarely ... -
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 ... -
PhylloTrees: Phyllotactic Patterns for Tree Layout
(The Eurographics Association, 2006)Motivations for drawing hierarchical structures are probably as diverse as datasets to visualize. This ubiquity of tree structures has lead to a manifold of tree layout algorithms and tree visualization systems. While many ... -
