%% Attachments to Specific Vertex in 2-D Delaunay Triangulation % Locate and plot the attachments to a specific vertex. % Copyright 2015 The MathWorks, Inc. %% % Create a Delaunay triangulation from a set of random points. x = gallery('uniformdata',[20,1],0); y = gallery('uniformdata',[20,1],1); DT = delaunayTriangulation(x,y); %% % Find the triangles attached to the fifth vertex. ti = vertexAttachments(DT,5); ti{:} %% % Plot the triangulation. Plot the triangles attached to vertex 5 in red. triplot(DT) hold on triplot(DT(ti{:},:),x,y,'Color','r') % vertex 5 (in red) hold off
