[vtkusers] vtkGlyph3D not updating?

[Frank Conradie]

Hi there

I'm using vtkGlyph3D to display a number of identical polydatas. This works
great when I initially create the whole filter chain and render it, but when
I modify either the source polydata or the input points polydata, the glyphs
are not updated.

Is this standard behaviour for vtkGlyph3D, or am I missing something?

Thanks,
Frank Conradie
