Covering both volume and surface meshes, the authors fully explain how and why these meshing algorithms work. The book is one of the first to integrate a vast amount of cutting-edge material on delaunay triangulations. It begins with introducing the problem of mesh generation and describing algorithms for constructing delaunay triangulations.
Delaunay refinement algorithms for mesh generation construct meshes of triangles or tetrahedra (“elements”) that are suitable for applications like interpolation, rendering, terrain databases, geographic information systems, and most demandingly, the solution of partial differential equations by the finite element method.
A surface delaunay ball is a ball circumscribing a mesh facet and centered on the surface. Distance_bound is an upper bound for the distance between the circumcenter of a mesh facet and the center of a surface delaunay ball of this facet. Given this surface type, the surface mesh generator will use an automatically generated traits class.

Delaunay mesh generation method is a common method for unstructured mesh (or unstructured grid) generation. Delaunay mesh generation method can conveniently add new points to the existing mesh without remeshing the whole domain. However, the quality of the generated mesh is not high enough if compared with some mesh generation methods.

The three most widely used techniques for parallel mesh gener-ation are delaunay [13], advance front, and edge subdivision. In this paper, we use the delaunay technique because it can mathemat-ically guarantee the quality of the mesh. Specifically, we focus on constrained delaunay triangulation [7] and we explore concurrency.
