The Vertex object gives access to the geometry vertices of an X3DObject's Primitive. A Vertex is the object PolygonMesh specifics of the Point object.
You can access vertices from Edge::GetVertices, PolygonFace::GetVertices and PolygonMesh::GetVertices.
using namespace XSI; using namespace MATH; Application app; Model root = app.GetActiveSceneRoot(); X3DObject myCube; root.AddGeometry( L"Cube", L"MeshSurface", L"", myCube ); PolygonMesh mesh(myCube.GetActivePrimitive().GetGeometry()); Vertex vertex0(mesh.GetVertices().GetItem(0)); app.LogMessage( L"Number of nodes for Vertex 0: " + CValue(vertex0.GetNodes().GetCount()).GetAsText() );
