What is the problem ?  Is it different point type, or different requirements
in the vertex/cell types ?  In the latter case, it might also be possible
to combine the requirements on vertex/cell types in order to have one
triangulation type that works in both cases.  Then you avoid the copy
completely.

"a failed assertion" ?
