I haven't tried this out , but you can try this . 
Since vtkGlyphSource2d returns a vtkPolyData , why not use an vtkAppendPolyData and combine the outputs from the two sources together and then set it to the SourceConnection . 

I think that should work .

Hello,

 

I've got the following code and this works fine:

 

vtkGlyphSource2D cross = vtkGlyphSource2D.New();

cross.SetFilled(0);

cross.SetGlyphTypeToCross();

 

vtkGlyphSource2D circle = vtkGlyphSource2D.New();

circle.SetGlyphTypeToCircle();

 

vtkGlyphSource2D square = vtkGlyphSource2D.New();

square.SetGlyphTypeToSquare();

 
vtkGlyph2D glyph = vtkGlyph2D.New();
glyph.SetColorModeToColorByScalar();
glyph.SetScaleModeToDataScalingOff();
glyph.SetIndexModeToScalar();
 
 
glyph.SetSourceConnection(0, cross.GetOutputPort());
glyph.SetSourceConnection(1, circle.GetOutputPort());
glyph.SetSourceConnection(2, square.GetOutputPort());

 

But now I want to append (or combine) an output port to an existing source connection. So that source connections with index 0 shows cross as well as circle. I have no idea how I can solve this problem. 

 

Do you understand what I mean or do you need more information to help? Do you have any suggestions for this problem? 

 

Thank you very much!

Lukas
