<p class="MsoNormal">You could use the Programmable Filter to create a new structured grid with the C+1 number of points in each dimension and then set the point data array in the C-sized grid to be a cell data array in the (C+1)-sized grid. The data layout
is such that that should work. However, you will need to set up the points manually.<u></u><u></u></p>

<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">I have a “Structured (Curvilinear) Grid” (*.vts), which gets read in as 314531 cells and 330000 points. I would like to tell Paraview that this is equidistant
cell-centered data (330000 cells). I want every cell to get one color, such that color interpolation becomes correct.
