<div dir="ltr">Raphael,<div>In talking to Dave, it seems that indeed you have found a bug in the writer (and in the specification). It does not seem to be a way to save field data unless your dataset is of type FIELD (a collection of arrays). The arrays attached to POINT_DATA (or CELL_DATA) which are designated as FIELD have to have the same number of tuples as the points (or cells). The terminology is kind of confusing as well. Would you mind filing a bug report.

<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">The way I understand the file format specification it should be illegal to define a FIELD dataset in addition to, e.g, STRUCTURED_POINTS, as I can find it neither explicitly allowed
(there is only mention of one dataset per file) nor presented in an example. It therefore seems like an accidental feature in vtk that I can actually read back the produced files.<br></div></div></blockquote><div><br></div></div></div><div dir="ltr"><div class="gmail_quote"><div>A FIELD dataset is a way to specify data without topological or geometrical structure.
