VTK-m now provides the following filters with the default policy as part of the vtkm_filter library: - CellAverage - CleanGrid - ClipWithField - ClipWithImplicitFunction - Contour - ExternalFaces - ExtractStructured - PointAverage - Threshold - VectorMagnitude By building these as a library we hope to provide faster compile times for consumers of VTK-m when using common configurations.
