Accelerated, High-Quality Refraction Computations for Volume Graphics
(The Eurographics Association, 2005)We present an efficient framework for the high-quality rendering of discretely sampled surface-based objects with refractive effects. This requires an accurate estimation of the refraction coefficients, paired with efficient ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
End-to-End Data Reduction and Hardware Accelerated Rendering Techniques for Visualizing Time-Varying Non-uniform Grid Volume Data
(The Eurographics Association, 2005)We present a systematic approach for direct volume rendering terascale-sized data that are time-varying, and possibly non-uniformly sampled, using only a single commodity graphics PC. Our method employs a data reduction ... -
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, ... -
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 ... -
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 ... -

(The Eurographics Association, 2003)This paper describes the design and performance of an interactive visualization system developed specifically for improved understanding of time-varying volume data from thermal flow simulations for vehicle cabin and ... -
Volume CAD
(The Eurographics Association, 2003)With the transition of the most fundamental data in manufacturing from drawings to three-dimensional (3D) CAD (Computer Aided Design) data, we are now able to fabricate products with beautiful curved surfaces, for example, ... -
A Volume Rendering Approach for Sea Surfaces Taking into Account Second Order Scattering Using Scattering Maps
(The Eurographics Association, 2003)We present a fast volume rendering technique for sea surfaces taking into account second order scattering using graphics hardware. To generate realistic images of the sea surfaces, accurate simulation of light transport ... -
Integrating Pre-Integration Into The Shear-Warp Algorithm
(The Eurographics Association, 2003)The shear-warp volume rendering algorithm is one of the fastest algorithms for volume rendering, but it achieves this rendering speed only by sacrificing interpolation between the slices of the volume data. Unfortunately, ... -
Hybrid Forward Resampling and Volume Rendering
(The Eurographics Association, 2003)The transforming and rendering of discrete objects, such as traditional images (with or without depths) and volumes, can be considered as resampling problem - objects are reconstructed, transformed, filtered, and finally ... -
Accuracy-Based Sampling and Reconstruction with Adaptive Grid for Parallel Hierarchical Tetrahedrization
(The Eurographics Association, 2003)Recent advances in volume scanning techniques have made the task of acquiring volume data of 3-D objects easier and more accurate. Since the quantity of such acquired data is generally very large, a volume model capable ... -
Multiresolution Volume Simplification and Polygonization
(The Eurographics Association, 2003)We propose a multiresolution volume simplification and polygonization algorithm. Traditionally, voxel-based algorithms lack the adaptive resolution support and consequently simplified volumes quickly lose sharp features ... -
Cell Projection of Convex Polyhedra
(The Eurographics Association, 2003)Finite element methods commonly use unstructured grids as the computational domain. As a matter of fact, the volume visualization of these unstructured grids is a time consuming task. Here, the fastest known object order ... -
