Q: How to use an arbitrary object as glyph?

[Charles Law]

<x-flowed>Mirco,

You should be able to polyData->GetPointData()->SetScalars(...) to color 
the points in you data set (interpolated along the line segments).

polyData->GetCellData()->SetScalars(...) will color the lines (cells) or 
poly lines.

Charles.
