How to read vertex normal in FBXShape?

[Anonymous]

I am working to develope a loader that deal with FBXShape. However, I am not sure, how to correctly read the vertex and normal of a FBXShape iterating each traiangle.

I know I can retreive the list of vertex and normal directly as a list usning following code,

FbxVector4* pControlPoints = pShape->GetControlPoints();

and 

FbxLayerElementArrayTemplate<FbxVector4>* pNormals = wwNULL;
wwBool status = pShape->GetNormals(&pNormals);

But these doesn;t give me the map with each geomtry triangle as I get in FBXMesh using, 

int controlPointIndex= pMesh->GetPolygonVertex(triIter, vertexIter);

and 

FbxVector4 fbxNormal;

pMesh->GetPolygonVertexNormal(triIter, vertexIter, fbxNormal);

How can I do that? Any help?
