Select MeshVS triangle and get coordinates

Hi,

I am trying to select a triangle of a MeshVS_Mesh in my V3DView. I do this in an open local context:

context->OpenLocalContext();
context->Load(aisMesh);
context->SetSelectionMode(aisMesh, 8);
context->Activate(aisMesh, 8);

I can see how the triangles becomes selected when I click on it. But how can I get the coordinates of the triangle?

Regards
SK
