vtk-developers，
Hi,all:
    I am studying the vtkMarchingCube Class. I meet the function "vtkMarchingCubesTriangleCases::GetCases()". I find the include file "vtkMarchingCubeCases.h", and find the function is static in struct:
struct VTK_COMMON_EXPORT vtkMarchingCubesTriangleCases 
{
  EDGE_LIST edges[16];
  static vtkMarchingCubesTriangleCases* GetCases();
};
But I can't find the implementation of it. Who can tell me where it is, or what the function do. 
Thanks a lot.
