Hi,
thanks for reading.

I have something like this.

An unstructured grid of points. The unstructured grid has two arrays.

I want to set glyphs for the points.
The size of the glyph must ceom from the array 2 and the colour of the glyph must come from the array 1.

The code fragments are as follows.
//m_unstructuredgrid is vtkUnstructuredGrid object
m_unstructuredgrid->GetPointData()->AddArray(GlyphColourArray);
m_unstructuredgrid->GetPointData()->AddArray(GlyphSizeArray);

m_glyph3D->SetInput(m_unstructuredgrid);
//m_spheresource is vtkSphereSource object
m_glyph3D->SetSource(m_spheresource->GetOutput());
m_glyph3D->SetScaleModeToScaleByScalar();

m_glyphmapper->SetInput(m_glyph3D->GetOutput());

m_glyphactor->SetMapper(m_glyphmapper);

The question is how to tell VTK to use GlyphColourArray for the glyph colours and GlyphSizeArray for the glyph sizes?

Thank you,
david michell
