Get Interface Extrema about bitpit HOT 3 CLOSED

Hi Alice,
what do you mean with "extremal points" of an interface? Do you mean its vertices? If yes, here an example is:
Let's extract an interface from a voloctree object (here patch is a pointer to a voloctree object) using its id (be id a consistent long) and ask for its vertices:
ConstProxyVector interfaceVertexIds = patch->getInterface(id).getVertexIds();
loop over the obtained vertices and ask for their coordinates storing them in an array<double,3>
const int nCellVertices = interfaceVertexIds.size();
for(int k = 0; k < nCellVertices; ++k){
std::array<double,3> v_coord = patch->getVertexCoords(interfaceVertexIds[k]);
}

If you meant something else, please explain me exactly what you mean with "extremal points" of an interface.

Sorry, obviously nCellVertices is not an happy choice, but it is not wrong. I should use something less cryptic like nInterfaceVertices. Anyway...

Hello Marco,

sorry I am late for answering. Yes it was that I meant; thank you so much for your help, I was pretty sure there was a better manner to study the vertices of an interface. I am still testing and it is very helpful for me now.
