[vtkusers] Problem with vtkcolor transfer function

[Albert King]

Hi All,
 
I am new to vtk and I am trying to incorporate color transferfunction to the volume rendering .I have pasted the code snippet.Is it a proper method to incoporate color transfer function after the skin mapper.Can I pipeline color transfer funtion directly to the dicom image reader.Pl Help.Thanks in Advance.
