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 ...
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 ...
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 ...
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 ...
