Try passing your grid through CellCenters filter first.

<pre wrap=""> Hello, me again.
This time I'm facing trouble visualizing glyphs on my structured grid.
Suppose I have done it right there is some vector data:
vtkFloatArray *v2 = vtkFloatArray::New();
v2->SetNumberOfComponents(3);
for (unsigned i = 0; i < noCells; i++){
v2->InsertNextTuple3(i,i,i);
}
assigned to the structured grid cell centers:
sGrid->GetCellData()->SetVectors(v2);
Now creating some glyphs
vtkConeSource *cone = vtkConeSource::New();
cone->SetResolution(6);
vtkGlyph3D *glyph = vtkGlyph3D::New();
glyph->SetInput( *sGrid* );
glyph->SetSourceConnection(cone->GetOutputPort());
glyph->SetVectorModeToUseNormal();
glyph->SetScaleModeToScaleByVector();
glyph->SetScaleFactor(0.25);
results in some arrows located at the structured grid points (sGrid)
instead of the cell centers.
* So how do I give vtkGlyph3D the cell centers of the structured
grid as input?
* And how does the gylph filter know it should represent the vector
data?!
