Transition from VTK 8.0 to VTK 9.0

This section lists categories of code changes necessary to build Slicer with VTK 9.0. Each category has a short description, an example error message, a suggested upgrade path, and references to relevant commits.


Add missing std namespace identifier

To fix error messages similar to: 



Replace code like this:



  vtkIdType*  cellPoints;



By this:



#if VTK_MAJOR_VERSION >= 9 || (VTK_MAJOR_VERSION >= 8 && VTK_MINOR_VERSION >= 90)
  const vtkIdType*  cellPoints;
#else
  vtkIdType*  cellPoints;
#endif








Add missing std namespace identifier


To fix error messages similar to:



/usr/include/c++/5/iosfwd:162:34: note:   ‘std::ifstream’
/tmp/SPHARM-PDM/Modules/CLI/MetaMeshTools/MeshMath.cxx:4082:5: error: ‘ofstream’ was not declared in this scope
     ofstream output;
     ^



/usr/include/c++/5/iosfwd:162:34: note:   ‘std::ifstream’
/tmp/SPHARM-PDM/Modules/CLI/MetaMeshTools/MeshMath.cxx:4117:5: error: ‘ofstream’ was not declared in this scope
     ofstream output;
     ^



Replace code like this:



    ifstream input;
    ofstream output;



By this:



    std::ifstream input;
    std::ofstream output;
