cgal_cdt2_get_connectivity - Get the connectivity of cdt2,constrained Delaunay triangulation.

Calling Sequence

tri = cgal_cdt2_get_connectivity(ptr);

Parameters

Examples

x = [5 1 6];
y = [2 6 6];
C=[8.    2.     7.    4.;6.    4.5    4.    5.;3.    6.     3.    7.;3.    4.     2.    3.;9.    4.     8.    7.];
[tri,ptr] = cgal_constraind_delaunay_2([],[],C);
cgal_cdt2_insert_points(ptr,x,y);
tri = cgal_cdt2_get_connectivity(ptr);
coord = cgal_cdt2_get_coord(ptr);
clf();
X=coord(:,1)';
Y=coord(:,2)';
[nbtri,nb] = size(tri);
tri = [tri tri(:,1)];
for k = 1:nbtri
plot2d(X(tri(k,:)),Y(tri(k,:)),style = 2);
end
cgal_cdt2_delete(ptr,"ptr");
