<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I believe the issue is that the glyph by cell data because the glyphs are placed on the points rather than the cells. Thus, all cell data is removed from the vectors list. Try running the cell centers filter and then apply the glyphs to that. Alternatively you can run the point to cell data filter, but that will modify the data.<BR>

<BR>
You can do it if you apply the "Generate Surface Normals" filter. That gives you point data "Normals" that can be glyphed.<BR>
<BR>
Maybe someone else that is more well versed in VTK data structures can chime in on why "cellNormals" shows up in the color combo-box but is not really considered to be a real point or cell data attribute (i.e. doesn't show up in the Information pane as a Data Array).<BR>

Why is that / how can I change it so that I can glyph the normals?<BR>
