Accessing VTK filters through conduit mesh blueprint?

[mlohry]

Is there a path to using the many useful VTK filters on conduit data? vtkCellDataToPointData for example, I would like to pass conduit data with cell-centered data and get back vertex-centered interpolated data.

@mlohry, in Ascent we don't use VTK itself, only VTK-m, which is a separate library.

We do have a "recenter" filter.

Conduit does not have any direct linkage to VTK itself either.

Since VisIt uses VTK, it includes routines that to flip between VTK and Conduit representations.

I am not sure, but the VTK library could provide these. This is the case for MFEM (we helped write conduit to/fro mfem implementation)
