Triangulirajmo mnogokotnik [PDF]

open access: yesGeodetski Vestnik, 2000
This paper considers different approaches how to divide polygons intotriangles what is known as a polygon triangulation. Polygons can be very complex in geodesic applications (they could have a lot of concave vertices, they could contain holes) therefore

Research on 3D modeling method of complex rock strata surfaces based on unit divisio

open access: yesGong-kuang zidonghua, 2017
In view of the problem that existing 3D modeling method of rock strata surfaces does not systematically consider the construction of 3D modeling of complex rock strata surfaces with geological conditions such as fault and collapse column, horizontal ...

Computing Three-dimensional Constrained Delaunay Refinement Using the GPU

open access: yes, 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 ...

A Novel Model of Conforming Delaunay Triangulation for Sensor Network Configuration

open access: yesAbstract and Applied Analysis, 2015
Delaunay refinement is a technique for generating unstructured meshes of triangles for sensor network configuration engineering practice. A new method for solving Delaunay triangulation problem is proposed in this paper, which is called endpoint triangle’

Environment Mapping Algorithm Using Semantic Description and Constrained Delaunay Triangulation

open access: yesElektronika ir Elektrotechnika, 2019
The article discusses the issue of creating an environment’s map with semantic division of areas. This simplifies some aspects of mobile robot control and permits the robot to carry out tasks issued in a human-understandable form. The article presents an

Two triangulations methods based on edge refinement [PDF]

open access: yes, 2003
In this paper two curvature adaptive methods of surface triangulation are presented. Both methods are based on edge refinement to obtain a triangulation compatible with the curvature requirements.

Properties of the Delaunay triangulation

open access: yesProceedings of the thirteenth annual symposium on Computational geometry - SCG '97, 1997
We defined several functionals on the set of all triangulations of the finite system of points in d-space achieving global minimum on the Delaunay triangulation (DT). We consider a so called "parabolic" functional and prove it attains its minimum on DT in all dimensions.
