An Evaluation of Using Real-time Volumetric Display of 3D Ultrasound Data for Intracardiac Catheter Manipulation Tasks
(The Eurographics Association, 2005)
The enthusiasm for novel, minimally invasive, catheter based intracardiac procedures has highlighted the need to provide accurate, real-time, anatomically based image guidance to decrease complications, improve precision, ...
A Multiresolution Volume Rendering Framework for Large-Scale Time-Varying Data Visualization
(The Eurographics Association, 2005)
We present a new parallel multiresolution volume rendering framework for large-scale time-varying data visualization using the wavelet-based time-space partitioning (WTSP) tree. Utilizing the wavelet transform, a largescale ...
A Simple and Flexible Volume Rendering Framework for Graphics-Hardware-based Raycasting
(The Eurographics Association, 2005)
In this work we present a flexible framework for GPU-based volume rendering. The framework is based on a single pass volume raycasting approach and is easily extensible in terms of new shader functionality. We demonstrate ...
Introducing Topological Attributes for Objective-Based Visualization of Simulated Datasets
(The Eurographics Association, 2005)
Recent development in the design of multi-dimensional transfer functions allows us to automatically generate comprehensible visualization images of given volumes by taking into account local features such as differentials ...
iSBVR: Isosurface-aided Hardware Acceleration Techniques for Slice-Based Volume Rendering
(The Eurographics Association, 2005)
In this paper, we examine the performance of the early z-culling feature on current high-end commodity graphics cards and present an isosurface-aided hardware acceleration algorithm for slice-based volume rendering (iSBVR) ...
A Virtual Reality Toolkit for the Diagnosis and Monitoring of Myocardial Infarctions
(The Eurographics Association, 2005)
We have developed a software system that takes standard electrocardiogram (ECG) input and interprets this input along with user-defined and automatically defined markers to diagnose myocardial infarctions (MI). These ...
Combining Point Clouds and Volume Objects in Volume Scene Graphs
(The Eurographics Association, 2005)
This paper describes an extension to the technical framework of Constructive Volume Geometry (CVG) in order to accommodate point clouds in volume scene graphs. It introduces the notion of point-based volume object (PBVO) ...
An Integrated Pipeline of Decompression, Simplification and Rendering for Irregular Volume Data
(The Eurographics Association, 2005)
Very large irregular-grid volume data sets are typically represented as tetrahedral mesh and require substantial disk I/O and rendering computation. One effective way to reduce this demanding resource requirement is ...
A Simplified Model for Inhomogeneous Subsurface Scattering
(The Eurographics Association, 2005)
In recent years there has been considerable interest in modeling realistic subsurface light scattering in materials such as marble, human skin, or clouds. Many of these models provide a solution for the transport equation ...
GPU-based Object-Order Ray-Casting for Large Datasets
(The Eurographics Association, 2005)
We propose a GPU-based object-order ray-casting algorithm for the rendering of large volumetric datasets, such as the Visible Human CT datasets. A volumetric dataset is decomposed into small sub-volumes, which are then ...
