A quick list of where the primary classes that will go into VTKM.

High level classes:

• vtkm::vtkAllocators [ dax ]
• vtkm::vtkMappedDataSets [ dax ]
• vtkm::Filters [ eavl ]
  • pistons halo finder
• vtkm::Mutators [ eavl ] + additive fields
• vtkm::OpenGLInterop [ dax + piston ]

Mid level:

• vtkm::ArrayHandle [dax]
  • dynamic info from eavl
• vtkm::CellSet [eavl]
  • Includes the Explicit and Implicit versions
• vtkm::DataSet [eavl]
  • Holds a Coordinate field
  • Holds a collection of CellSets
  • Holds a collection of array handles as fields

Low level:

• vtkm::DeviceAdapter [dax]
• vtkm::DeviceAdapterGeneral [dax]
• vtkm::TopologyMap [eavl]
• vtkm::WorkletConcept [ eavl + dax ]
