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 ... -
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 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 ... -
Representation of Objects with Sharp Details in Truncated Distance Fields
(The Eurographics Association, 2005)We present a new approach for voxelization of implicit solids which contain sharp details. If such objects are processed by common techniques, voxelization artifacts may appear, resulting, among others, in jaggy edges in ... -
Robust Generation of Signed Distance Fields from Triangle Meshes
(The Eurographics Association, 2005)A new method for robust generation of distance fields from triangle meshes is presented. Graphics hardware is used to accelerate a technique for generating layered depth images. From multiple layered depth images, a binary ... -
Scaffolding-based Segmentation of Coronary Vascular Structures
(The Eurographics Association, 2005)The coronary arteries are essential for the proper function of the human heart. However, they are generally difficult to segment in volume datasets separately from the other blood-filled cavities of the heart. The major ... -
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 ... -
Simplification of Unstructured Tetrahedral Meshes by Point Sampling
(The Eurographics Association, 2005)Tetrahedral meshes are widely used in scientific computing for representing three-dimensional scalar, vector, and tensor fields. The size and complexity of some of these meshes can limit the performance of many visualization ... -
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 ... -
Texturing and Hypertexturing of Volumetric Objects
(The Eurographics Association, 2005)Texture mapping is an extremely powerful and flexible tool for adding complex surface detail to an object. This paper introduces a method of surface texturing and hypertexturing complex volumetric objects in real-time. We ... -
Time-Varying Interval Volumes
(The Eurographics Association, 2005)In this paper, we study the interval segmentation and direct rendering of time-varying volumetric data to provide a more effective and interactive volume rendering of time-varying structured and unstructured grids. Our ... -
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 ... -
Visualization of Time-Varying Volumetric Data using Differential Time-Histogram Table
(The Eurographics Association, 2005)We introduce a novel data structure called Differential Time-Histogram Table (DTHT) for visualization of timevarying scalar data. This data structure only stores voxels that are changing between time-steps or during transfer ... -
Volume Rendering for High Dynamic Range Displays
(The Eurographics Association, 2005)Dynamic range restrictions of conventional displays limit the amount of detail that can be represented in volume rendering applications. However, high dynamic range displays with contrast ratios larger than 50;000 : 1 have ... -
Volumetric Reconstruction, Compression and Rendering of Natural Phenomena from Multi-Video Data
(The Eurographics Association, 2005)Lately, new methods for the acquisition of time-varying, volumetric data for photo-realistic rendering of semitransparent, volumetric phenomena like fire and smoke have been developed. This paper presents a wavelet-coding ...
