I want read a gaussian cube file with vtkGaussianCubeReader and show isosurface of the Molecular orbitals similar as ![image](https://discourse.vtk.org/uploads/default/original/2X/b/bea2912cee723cdf2f2be30ac0d76063ba9273c3.jpeg)  
I found some class such as vtkProgrammableElectronicData and vtkMolecule but I dont know how can I send cube file data to them.  
can anyone help me how to do this?

Thank you.
