Efficient Terrain Triangulation and Modification Algorithms for Game Applications
International Journal of Computer Games Technology, 2008 An efficient terrain generation algorithm is developed, based on constrained conforming Delaunay triangulation. The density of triangulation in different regions of a terrain is determined by its flatness, as seen from a height map, and a control map ...

ISPRS International Journal of Geo-Information, 2020 Building pattern recognition is fundamental to a wide range of downstream applications, such as urban landscape evaluation, social analyses, and map generalization. Although many studies have been conducted, there is still a lack of satisfactory results,

Counting Triangulations and other Crossing-Free Structures Approximately [PDF]
, 2014 We consider the problem of counting straight-edge triangulations of a given set $P$ of $n$ points in the plane. Until very recently it was not known whether the exact number of triangulations of $P$ can be computed asymptotically faster than by ...

International Journal of Digital Earth, 2021 The spatial distribution of power facilities is uneven, thereby making the topology of geographical wiring diagrams (GWDs) based on the actual coordinates unclear. A single-line diagram has the advantage of a clear topology but it lacks spatial locations.

Recovery of Asteroids from Observations of Too-Short Arcs by Triangulating Their Admissible Regions
Journal of Astronomy and Space Sciences, 2021 The data set collected during the night of the discovery of a minor body constitutes a too-short arc (TSA), resulting in failure of the differential correction procedure.

Constrained boundary recovery for three dimensional Delaunay triangulations [PDF]
International Journal for Numerical Methods in Engineering, 2004 AbstractA new constrained boundary recovery method for three dimensional Delaunay triangulations is presented. It successfully resolves the difficulties related to the minimal addition of Steiner points and their good placement. Applications to full mesh generation are discussed and numerical examples are provided to illustrate the effectiveness of ...

Planar maps, circle patterns and 2d gravity [PDF]
, 2013 Via circle pattern techniques, random planar triangulations (with angle variables) are mapped onto Delaunay triangulations in the complex plane. The uniform measure on triangulations is mapped onto a conformally invariant spatial point process.

Computing Three-dimensional Constrained Delaunay Refinement Using the GPU
, 2019 We propose the first GPU algorithm for the 3D triangulation refinement problem. For an input of a piecewise linear complex $\mathcal{G}$ and a constant $B$, it produces, by adding Steiner points, a constrained Delaunay triangulation conforming to ...
