Hi, all

Currently, I'm doing some isotropic remeshing jobs. I try to remesh  a Delaunay triangluation_3 which has 1~5 million vertices.

At the end of each optimization step, the location of the vertices will be update to another place.  and as i know, there are two method to finish this update:

1)  using one triangulation object and use the   "Triangluation_3::move_point()"  operation;

2) using two copy triangulation objects.  and  use the "t.swap ( Triangulation_3 & tr)" operation to update the whole triangulation. 

Is there any one know the efficient between these two operations, which one is more fast?

Best regards
