[vtk-developers] Saving fields (arrays not associated with points or cells) in VTK legacy or VTK xml files

[Will Schroeder]

Ahh yes I see, the wider usage of field data came after the initial
implementation which was probably in 1994 :-) so there were probably bugs
backed into the cake. I don't recall the last time we changed the legacy
file formats, so I'm curious is this something that is being considered?
(sorry I missed the discussion)
