Adaptive Volume Construction from Ultrasound Images of a Human Heart
(The Eurographics Association, 2004)We present a volume modelling approach based on sequences of two-dimensional ultrasound images. Though generally applicable to arbitrary freehand ultrasound, our method is designed for the reconstruction of timevarying ... -
Efficient Isosurface Tracking Using Precomputed Correspondence Table
(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -
Visualization of Anatomic Tree Structures with Convolution Surfaces
(The Eurographics Association, 2004)We present a method for visualizing anatomic tree structures, such as vasculature and bronchial trees based on clinical CT- or MR data. The vessel skeleton as well as the diameter information per voxel serve as input. Our ... -
Efficient Display of Background Objects for Virtual Endoscopy using Flexible First-Hit Ray Casting
(The Eurographics Association, 2004)Many applications of virtual endoscopy require the display of background objects behind the semi-transparent surface of the investigated organ. This paper deals with pre-processing and visualization of background objects ... -
Software Landscapes: Visualizing the Structure of Large Software Systems
(The Eurographics Association, 2004)Modern object-oriented programs are hierarchical systems with many thousands of interrelated subsystems. Visualization helps developers to better comprehend these large and complex systems. This paper presents a three-dimensional ... -
Meshless Isosurface Generation from Multiblock Data
(The Eurographics Association, 2004)We propose a meshless method for the extraction of high-quality continuous isosurfaces from volumetric data represented by multiple grids, also called "multiblock" data sets. Multiblock data sets are commonplace in ... -
Volume Visualization and Visual Queries for Large High-Dimensional Datasets
(The Eurographics Association, 2004)We propose a flexible approach for the visualization of large, high-dimensional datasets. The raw, highdimensional data is mapped into an abstract 3D distance space using the FastMap algorithm, which helps, together with ... -
Medical Applications of Multi-Field Volume Rendering and VR Techniques
(The Eurographics Association, 2004)This paper reports on a new approach for visualizing multi-field MRI or CT datasets in an immersive environment with medical applications. Multi-field datasets combine multiple scanning modalities into a single 3D, ... -

(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -
Occlusion Culling for Sub-Surface Models in Geo-Scientific Applications
(The Eurographics Association, 2004)Modern graphics cards support occlusion culling in hardware. We present a three pass algorithm, which makes efficient use of this feature. Our geo-scientific sub-surface data sets consist typically of a set of high resolution ... -
Interactive High Quality Trimmed NURBS Visualization Using Appearance Preserving Tessellation
(The Eurographics Association, 2004)Trimmed NURBS models are the standard representation used in CAD/CAM systems and accurate visualization of large trimmed NURBS models at interactive frame rates is of great interest for industry. To visualize the quality ... -
Browsing and Visualizing Digital Bibliographic Data
(The Eurographics Association, 2004)Access to publications is provided by conventional libraries, digital libraries operated by learned societies or commercial publishers, and a huge number of web sites maintained by the scientists themselves or their ... -
A Botanically Inspired High-Dimensional Visualization with Multivariate Glyphs
(The Eurographics Association, 2004)It is difficult for the average viewer to assimilate and comprehend huge amounts of high-dimensional data. It is important to present data in a way that allows the user a high level understanding of the overall organization ... -
Generalized Distance Transforms and Skeletons in Graphics Hardware
(The Eurographics Association, 2004)We present a framework for computing generalized distance transforms and skeletons of two-dimensional objects using graphics hardware. Our method is based on the concept of footprint splatting. Combining different splats ... -
Visualization of Cardio-CT Data on Standard PC Hardware
(The Eurographics Association, 2004)In the last years, texture based volume rendering on the PC platform has proven very successful. Many methods that could formerly only be done with software renderers can now be done completely by the graphics hardware. ... -
Boundary Switch Connectors for Topological Visualization of Complex 3D Vector Fields
(The Eurographics Association, 2004)One of the reasons that topological methods have a limited popularity for the visualization of complex 3D flow fields is the fact that their topological structures contain a number of separating stream surfaces. Since these ... -
DTI Visualization with Streamsurfaces and Evenly-Spaced Volume Seeding
(The Eurographics Association, 2004)Experimental evidence has shown that water diffusion is anisotropic in organized tissues such as white matter or muscles. Diffusion Tensor Imaging is a non-invasive MR technique that measures water diffusion. DTI is used ... -
Ray Casting Curved-Quadratic Elements
(The Eurographics Association, 2004)We present a method for ray casting curved-quadratic elements in 3D. The advantages of this approach is that a curved element can be directly visualized. Conventionally, higher-order elements are tessellated with several ... -
Auralization I: Vortex Sound Synthesis
