Hello

I am new to cgal.

I am using a Constrained_triangulation_plus_2 to generate a mesh

The problem is that I want my triangulation to evolve over time, i.e., it
must be dynamic.

So at a given time t, I must input some constraints, and I do it like this

typedef CGAL::Constrained_Delaunay_triangulation_2<K, TDS, Itag>
DelaunayCDT;
typedef CGAL::Constrained_triangulation_plus_2<DelaunayCDT>  CDT;
CDT dt;

Vertex_handle va =  dt.insert(Point_2(x1, y1);
Vertex_handle1 vb =  dt.insert(Point_2(pc_local.points.at(i).x,
pc_local.points.at(i).    y));
dt.insert_constraint(va, vb);

And I do this in a for cycle to insert several constraints.
The problem is that at iteration t+1, I need to remove all the constraints I
inserted at iteration t.

How can I do this?

I could not find any method like  clear_constraints()

Thanks for the help

Miguel
