Hi,<BR>
thanks for reading.<BR>
<BR>
I have something like this.<BR>
<BR>
An unstructured grid of points. The unstructured grid has two arrays.<BR>
<BR>
I want to set glyphs for the points.<BR>
The size of the glyph must ceom from the array 2 and the colour of the glyph must come from the array 1.<BR>
<BR>
The code fragments are as follows.<BR>
//m_unstructuredgrid is vtkUnstructuredGrid object<BR>
m_unstructuredgrid-&gt;GetPointData()-&gt;AddArray(GlyphColourArray);<BR>
m_unstructuredgrid-&gt;GetPointData()-&gt;AddArray(GlyphSizeArray);<BR>
<BR>
m_glyph3D-&gt;SetInput(m_unstructuredgrid);<BR>
//m_spheresource is vtkSphereSource object<BR>
m_glyph3D-&gt;SetSource(m_spheresource-&gt;GetOutput());<BR>
m_glyph3D-&gt;SetScaleModeToScaleByScalar();<BR>
<BR>
m_glyphmapper-&gt;SetInput(m_glyph3D-&gt;GetOutput());<BR>
<BR>
m_glyphactor-&gt;SetMapper(m_glyphmapper);<BR>
<BR>
The question is how to tell VTK to use GlyphColourArray for the glyph colours and GlyphSizeArray for the glyph sizes?<BR>
<BR>
Thank you,<BR>
