HI, all

I'm trying to optimize(remeshing) a CDT by using (CVT) Centriod Voronoi Tessellation algorithms.

The CDT is exepcted to be refined after each iteration of CVT. In each iteration, the position of a vertex is updated.

I am using the CGAL::Delaunay_mesher_2<CDT, Criteria> for the refining jobs.

I wish the number of vertices are not changed after each iteration, however, it's always changed.

the "Criteria" is set to the default value.

So, What shoud i do to avoid the vertices number be changed ? Is it the problem of setting of Criteria value?

Thanks all~

Best regards

shuchu
