Visualization of Global Flow Structures Using Multiple Levels of Topology
(Springer and The Eurographics Association, 1999)
The technique for visualizing topological information in fluid flows is well known. However, when the technique is used in complex and information rich data sets, the result will be a cluttered image which is difficult to ...
Data-Dependent Surface Simplification
(The Eurographics Association, 1998)
In Scientific Visualization, surfaces have often attached data, e. g. cutting surfaces or isosurfaces in numerical simulations with multiple data components. These surfaces can be e. g. the output of a marching cubes ...
New Approaches for Particle Tracing on Sparse Grids
(Springer and The Eurographics Association, 1999)
Flow visualization tools based on particle methods continue to be an important utility of flow simulation. Additionally, sparse grids are of increasing interest in numerical simulations. In [14] we presented the advontages ...
Efficiently Rendering Large Volume Data Using Texture Mapping Hardware
(Springer and The Eurographics Association, 1999)
Volume rendering with texture mapping hardware is a fast volume rendering method available on high-end workstations. However, limited texture memory often prevents the method from being used to render large volume data ...
Enhancing the Visualization of Characteristic Structures in Dynamical Systems
(The Eurographics Association, 1998)
We present a thread of streamlets as a new technique to visualize dynamical systems in three-dimensional space. A trade-off is made between solely visualizing a mathematical abstraction through lowerdimensional manifolds, ...
Particle Tracing in σ-Transformed Grids using Tetrahedral 6-Decomposition
(The Eurographics Association, 1998)
Particle tracing in curvilinear grids often employs decomposition of hexahedral cells into 5 tetrahedra. This method has shortcomings when applied to sigma-transformed grids, a grid type having strongly sheared cells, ...
Advances in Quality Control of Intraoperative Radiotherapy
(Springer and The Eurographics Association, 1999)
Intraoperative radiotherapy is the kind of radiotherapy where the remains of a surgically not completely removed tumour are irradiated at the open situ of the patient. The current main drawback of this radiotherapy is the ...
A Comparison of Error Indicators for Multilevel Visualization on Nested Grids
(Springer and The Eurographics Association, 1999)
Multiresolution visualization methods have recently become an indispensable ingredient of real time interactive post processing. Here local error indicators serve as criteria where to refine the data representation on the ...
Parallel Multipipe Rendering for Very Large Isosurface Visualization
(Springer and The Eurographics Association, 1999)
In exploratory scientific visualization, isosurfaces are typi- cally created with an explicit polygonal representation for the surface using a technique such as Marching Cubes. For even moderate data sets, Marchching Cubes ...
A Client-side Approach towards Platform Independent Molecular Visualization over the World Wide Web
(Springer and The Eurographics Association, 1999)
A web-based, entirely platform independent Molecular Visualization System has been developed using state of the Internet programming techniques. This system offers the visualization of various molecular models, molecular ...
