Developer Meetings/20140128

To discuss

• New SlicerWizard to create extension (Matthew Woehlke). See mwoehlke-kitware/Slicer@3566-refactor-wizard
• VTK6 integration status update (Yuzheng Zhou). See integration status
  • Why?
    • VTK 6 doesn't provide backwards compatibility for lots of APIs with VTK 4 and 5.
    • In VTK 6, data and execution “models” (algorithms) are seperated. A vtkDataObject doesn't contain the pipeline information anymore.
  • What are needed to do:
    • Done: build system migration (conditional build Slicer and CTK using VTK 5 or VTK 6)
    • Done: removal of VTK 4 backwards compatibility superclasses (vtkProcessObject, vtkSource and all of their subclasses)
    • In progress (90% done): removal of the pipeline meta-data API from vtkDataObject (E.g. AllocateScalars(), SetWholeExtent(), etc.)
    • In progress (90% done): removal of Data Objects’ Dependency on the Pipeline (RequestData(), ExecuteData(), SetInput(), etc.)
    • Testing (TODO)
