WebBowyer and David Watson. They devised it independently of each other at the same time, and each published a paper on it in the same issue of The Computer Journal. The Bowyer Watson algorithm[2, 3] works by adding points, one at a time, to a alidv Delaunay triangulation of a subset of the desired points. The description of this algorithm is simple.

"WebThe basic Bowyer-Watson algorithm is an incremental algorithm in which vertices are inserted one-by-one. When a new vertex is inserted in an existing mesh, all the elements that violate the Delaunay empty circumcircle property form a Cavity. The elements in this cavity are removed and new elements are formed using new vertices as an apex of the ... " - Bowyer-watson 3d c++

Triangulating a 3D mesh from a set of data points

WebIn computational geometry, the Bowyer–Watson algorithm is a method for computing the Delaunay triangulation of a finite set of points in any number of dimensions. The algorithm can be also used to obtain a Voronoi diagram of the points, which is the dual graph of the Delaunay triangulation. WebAug 17, 2009 · 3D version implementation of Bowyer/Watson algorithm is almost the same as the 2D. Instead of eliminating lines that belong only to the triangles whose circumcirlce contains the newly added point, in 3D we eliminate the facets that belong only to the tetrahedra whose circumsphere contains the newly added point, then form new …
