WebMar 6, 2024 · The Bowyer–Watson algorithm is an incremental algorithm. It works by adding points, one at a time, to a valid Delaunay triangulation of a subset of the desired … 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 ...
