[vtkusers] TubeFilter on PolyData with constant Radius

[Johannes Strecha]

Hi,

I'm not sure if I understand your problem correctly. I assume you have the
polydata with the scalar you want to vary the tube radius by as a named
array in the pointData (as returned by yourPolyData.GetPointData()). You
could try to specify which array to process with the TubeFilters inherited
method SetInputArrayToProcess<http://www.vtk.org/doc/release/5.8/html/a00128.html#6bea16e1329609dbccce0ff8d2367484>(int
idx, int port, int connection, int fieldAssociation, const char
*name). fieldAssociation will most likely be FIELD_ASSOCIATION_POINTS, idx,
port, connection most likely 0. Check the class reference for further
information*.

Kind regards,
Johannes Strecha.
