WebMar 1, 2015 · The border vertices are the vertices that belong to the border edges. A naive way to find the border vertices is to iterate through all your edges, count how many polygons they belong to, and if they only belong to one polygon, then collect the edge's vertices as border vertices. Webboundary vertices lie in the same connected component. Suppose this is not true, and let x and y be the closest consecutive boundary vertices that lie in diﬀerent compo-nents. Let ℓ′ be the line through x and y, let ℓx be the line perpendicular to ℓ′ through x and ℓy be the line perpendic-ular to ℓ′ through y. (See Fig. 5.)

Webing vertices in the polygon are visible from each other (see Fig. 2). In this paper, we assume that along with the visibility graph, we have the cycles that correspond to the order of vertices on the boundary of the polygon and the holes. The cycle that corresponds to the external boundary of the polygon is called the external cycle(see Fig. 2).
