Minimizing local minima in terrains with higher-order Delaunay triangulations

چکیده
We show that triangulating a set of points with elevations such that the number of local minima of the resulting terrain is minimized is NP-hard for degenerate point sets. The same result applies when there are no degeneracies for higher-order Delaunay triangulations. Two heuristics are presented to minimize the number of local minima for higher-order Delaunay triangulations, and they are compared experimentally.

Drainage reality in terrains with higher-order Delaunay triangulations
Terrains are often modeled by triangulations. One of the criteria that a triangulation should have is “nice shape” triangles. Delaunay triangulation is a good way to formalize nice shape. Another criterion is reality of drainage in terrains. Natural terrains do not have many local minima and have drainage lines in the bottom of valleys. To achieve these characteristics, higher-order Delaunay tr...
متن کاملGenerating Realistic Terrains with Higher-Order Delaunay Triangulations
For hydrologic applications, terrain models should have few local minima, and drainage lines should coincide with edges. We show that triangulating a set of points with elevations such that the number of local minima of the resulting terrain is minimized is NP-hard for degenerate point sets. The same result applies when there are no degeneracies for higher-order Delaunay triangulations. Two heu...
متن کاملSlope Fidelity in Terrains with Higher-Order Delaunay Triangulations
Terrains are often modeled by triangulations and one of the criteria is that: triangulation should have “nice shape”. Delaunay triangulation is a good way to formalize nice shape. Another criterion is slope fidelity in terrains. In natural terrains there are no abrupt changes in slope. A triangulation for a terrain should use triangles of nice shape and have slope fidelity. To achieve these cha...
متن کاملTowards a Definition of Higher Order Constrained Delaunay Triangulations
When a triangulation of a set of points and edges is required, the constrained Delaunay triangulation is often the preferred choice because of its well-shaped triangles. However, in applications like terrain modeling, it is sometimes necessary to have flexibility to optimize some other aspect of the triangulation, while still having nicely-shaped triangles and including a set of constraints. Hi...
متن کاملOn the Number of Higher Order Delaunay Triangulations
Higher order Delaunay triangulations are a generalization of the Delaunay triangulation which provides a class of well-shaped triangulations, over which extra criteria can be optimized. A triangulation is order-k Delaunay if the circumcircle of each triangle of the triangulation contains at most k points. In this paper we study lower and upper bounds on the number of higher order Delaunay trian...
