Summary0002684: SNL: Cell centered isosurfaces
DescriptionCurrently to do isosurfaces of cell centered data you must first to 'CellToPoint' and then run the isosurface. We would like to have the isocontour filter show cell centered array and then automatically invoke CellToPoint on just the selected array and then isosurface.

Another approach is to regenerate the geometry so that there is a vertex at each cell center; copy the cell data to the new vertices; then invoke the standard contour algorithm.

I implemented this years ago in an OpenDX application and the results were, for some data, noticeably different because the averaging of CellToPoint was eliminated.

The size of the new geometry shrinks by half a cell on all edges but that actually makes sense.

I wonder if the dual-grid approach suggested by Kent would work on unstructured meshes...
