<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Have you tried ClampingOn() with ScalingOn().
Data scales outside the clamp range are reset to the range end points. The data
scale is then normalized to the range 0 – 1. All glyphs with a data scale
less than the lower clamp range are therefore mapped to zero. Provided data
scaling is on (SetScaleModeToDataScalingOn()), the composite scale factor, DataScale*ScaleFactor
will also be zero.</span></font></p>

glyphs using a vtkPlaneSource as the data points. It works perfectly –
when I have scaling on, the glyphs behave appropriately. However, when I
turn scaling off (whowing vector direction only) there are glyphs placed even
at points (on the vtkPlaneSource) that are outside the body (therefore
magnitude is implicitly zero).</span></font></p>
