### Declaration Section

    #include <vtkActor.h>
    #include <vtkCamera.h>
    namespace
    {
    void SaveSceneToFile(std::string fileName,
                         vtkActor *actor,
                         vtkCamera *camera);
    }

### Implementation Section

    namespace
    {
    #include <fstream>
    void SaveSceneToFile(std::string fileName,
                         vtkActor *actor,
                         vtkCamera *camera)
    {
    // Actor
    //  Position, orientation, origin, scale, usrmatrix, usertransform
    //Camera
    //  FocalPoint, Position, ViewUp, ViewAngle, ClippingRange
      std::ofstream saveFile(fileName, std::ofstream::out);
      double vector[3];
      double scalar;

      camera->GetFocalPoint(vector);
