The Half-Edge Tree: A Compact Data Structure for Level-of-Detail Tetrahedral Meshes
We propose a new data structure for the compact encoding of a Level-Of-Detail (LOD) model of a threedimensional scalar field based on unstructured tetrahedral meshes. Such data s...

Subdomain Aware Contour Trees and Contour Evolution in Time-Dependent Scalar Fields
For time-dependent scalar fields, one is often interested in topology changes of contours in time. In this paper, we focus on describing how contours split and merge over a certa...

Contouring 1- and 2-Manifolds in Arbitrary Dimensions
We propose an algorithm for contouring k-manifolds (k = 1, 2) embedded in an arbitrary n-dimensional space. We assume (n−k) geometric constraints are represented as polynomial e...
