The triangulations classes of CGAL provide high-level geometric functionalities such as location of a point in the triangulation, insertion, removal, or displacement of a point. They are build as a layer on top of a data structure called the triangulation data structure.
A triangulation is a collection of vertices and cells that are linked together through incidence and adjacency relations. Each cell gives access to its four ...
This package proposes data structures and algorithms to compute triangulations of points in any dimensions.
This paper presents the main algorithmic and design choices that have been made to implement triangulations in the computational geometry algorithms library ...
