Computing contour trees in all dimensions
H Carr, J Snoeyink, U Axen - Computational Geometry, 2003 - Elsevier
We show that contour trees can be computed in all dimensions by a simple algorithm that
merges two trees. Our algorithm extends, simplifies, and improves work of Tarasov and …

Flexible isosurfaces: Simplifying and displaying scalar topology using the contour tree
The contour tree is an abstraction of a scalar field that encodes the nesting relationships of
isosurfaces. We show how to use the contour tree to represent individual contours of a scalar …

Interactive comparison of scalar fields based on largest contours with applications to flow visualization
Understanding fluid flow data, especially vortices, is still a challenging task. Sophisticated
visualization tools help to gain insight. In this paper, we present a novel approach for the …
