上一次讲了三维画图,今天说一下约束测量画图。例如:
- X = [0 0; 16 0; 16 2; 2 2; 2 3; 8 3; 8 5; 0 5];
- C = [1 2; 2 3; 3 4; 4 5; 5 6; 6 7; 7 8; 8 1];
- dt = delaunayTriangulation(X, C);
- subplot(2,1,1);
- triplot(dt);
- axis([-1 17 -1 6]);
- xlabel('约束三角测量', 'fontweight','b');
- % Plot the constrained edges in red
- hold on;
- plot(X(C'),X(C'+size(X,1)),'-r', 'LineWidth', 2);
- hold off;
- % Now delete the constraints and plot the unconstrained Delaunay
- dt.Constraints = [];
- subplot(2,1,2);
- triplot(dt);
- axis([-1 17 -1 6]);
- xlabel('三角测量', 'fontweight','b');
