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 ...
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 ...
