Topology-Based Visualization of Time-Dependent 2D Vector Fields
(The Eurographics Association, 2001)
Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks ...
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 ...
Subdivision Surfaces for Scattered-data Approximation
(The Eurographics Association, 2001)
We propose a modified Loop subdivision surface scheme for the approximation of scattered data in the plane. Starting with a triangulated set of scattered data with associated function values, our scheme applies linear, ...
Vector and Tensor Field Topology Simplification on Irregular Grids
(The Eurographics Association, 2001)
Topology-based visualization of planar turbulent flows results in visual clutter due to the presence of numerous features of very small scale. In this paper, we attack this problem with a topology simplification method for ...
Extraction of Crack-free Isosurfaces from Adaptive Mesh Refinement Data
(The Eurographics Association, 2001)
Adaptive mesh refinement (AMR) is a numerical simulation technique used in computational fluid dynamics (CFD). It permits the efficient simulation of phenomena characterized by substantially varying scales in complexity ...
Non-manifold Mesh Extraction from Time-varying Segmented Volumes used for Modeling a Human Heart
(The Eurographics Association, 2005)
We present a new algorithm extracting and fairing surfaces from segmented volumes composed of multiple materials. In a first pass, the material boundaries in the volume are smoothed considering signed distance functions ...
Priority Streamlines: A context-based Visualization of Flow Fields
(The Eurographics Association, 2007)
Flow vector fields contain a wealth of information that needs to be visualized. As an extension of the well-known streamline technique, we have developed a context-based method for visualizing steady flow vector fields in ...
Adaptive Smooth Scattered-data Approximation for Large-scale Terrain Visualization
(The Eurographics Association, 2003)
We present a fast method that adaptively approximates large-scale functional scattered data sets with hierarchical B-splines. The scheme is memory efficient, easy to implement and produces smooth surfaces. It combines ...
Volume Deformations in Grid-Less Flow Simulations
(The Eurographics Association and Blackwell Publishing Ltd., 2009)
Abstract This paper presents a novel method for the extraction and visualization of volume deformations in grid-less point based flow simulations. Our primary goals are the segmentation of different paths through a mixing ...
Sound Tracing: Rendering Listener Specific Acoustic Room Properties
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
We present an acoustic rendering approach visualizing the listener-specific contribution of frequency-dependent pressure fields on a scene geometry with acoustic reflection and scattering properties. Our method facilitates ...
