Hierarchical Data Representations Based on Planar Voronoi Diagrams
(The Eurographics Association, 2000)
Multiresolution representation of high-dimensional scattered data is a fundamental problem in scientific visualization. This paper introduces a data hierarchy of Voronoi diagrams as a versatile solution. Given an arbitrary ...
Detecting Critical Regions in Scalar Fields
(The Eurographics Association, 2003)
Trivariate data is commonly visualized using isosurfaces or direct volume rendering. When exploring scalar fields by isosurface extraction it is often difficult to choose isovalues that convey "useful" information. The ...
Dense Geometric Flow Visualization
(The Eurographics Association, 2005)
We present a flow visualization technique based on rendering geometry in a dense, uniform distribution. Flow is integrated using particle advection. By adopting ideas from texture-based techniques and taking advantage of ...
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 ...
Visualization for Validation and Improvement of Three-dimensional Segmentation Algorithms
(The Eurographics Association, 2005)
The Berkeley DrosophilaTranscription Network Project (BDTNP) is developing a suite of methods that will allow a quantitative description and analysis of three dimensional (3D) gene expression patterns in an animal with ...
Multiresolution Techniques for Interactive Texture-based Rendering of Arbitrarily Oriented Cutting Planes
(The Eurographics Association, 2000)
We present a multiresolution technique for interactive texture based rendering of arbitrarily oriented cutting planes for very large data sets. Thismethod uses an adaptive scheme that renders the data along a cutting plane ...
Hierarchical Isosurface Segmentation Based on Discrete Curvature
(The Eurographics Association, 2003)
A high-level approach to describe the characteristics of a surface is to segment it into regions of uniform curvature behavior and construct an abstract representation given by a (topology) graph. We propose a surface ...
Structure-accentuating Dense Flow Visualization
(The Eurographics Association, 2006)
Vector field visualization approaches can broadly be categorized into approaches that directly visualize local or integrated flow and approaches that analyze the topological structure and visualize extracted features. Our ...
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 ...
Improving Topological Segmentation of Three-dimensional Vector Fields
(The Eurographics Association, 2003)
We present three enhancements to accelerate the extraction of separatrices of three-dimensional vector fields, using intelligently selected "sample" streamlines. These enhancements reduce the number of needed sample ...
