Antwort: vtkPolyData: changing line attributes

[Patric.Weis at mycrona.de]

If you are using OpenGL you can set the width of the lines of an actor by

     vtkActor->GetProperty()->SetLineWidth(...).

But I use vtkTubeFilter which produces a very good looking appearance of
the lines (e.g. .../graphics/examplesTcl/constrainedDelaunay.tcl).

Hi fellow vtker's,

I think this is straightforward, but I haven't found a reference
on how to do it.

I've created a vtkPolyData object that is a grid of lines.

The code fragment is

//-----Loop over the lines

...

pointID = gridPoints->InsertNextPoint( firstEndPoint);
pointList[0] = pointID;

pointID = gridPoints->InsertNextPoint( secondEndPoint);
pointList[0] = pointID;

gridLines->InsertNextCell( 2, pointList );

...

gridPolyData->SetPoints( gridPoints);
gridPolyData->SetLines( gridLines);

....

What I would like to do is to set the thickness of the lines.
Any insight would be most appreciated.

Regards,

Audrius
