<br>
<small>I have toyed around with the example and it is still displaying
nothing.<br>
So it is still broken, but not due to the basic errors which were made
before.<br>
<br>
I have found no reliable example and/or code snipped which would
display <b>my </b>streamlines (or any, actually)<br>
I'm sure this is because my vectors are defined on the structured grid
cell centers and not on the points.<br>
Is this so uncommon?!? I have played with vtkCellDataToPointData to
maybe transform the vectors to the points - with no result.<br>
<br>
So I'm still stuck. Hopefully Berk will post some usable streamTracer
example.<br>
See you.</small></font><br>

What is essential to create streamlines with vtkStreamTracer?<br>
I haven't found an example so far.<br>
<br>
<font color="#ff0000"><b>I have vector data stored on <u>structured
grid

<br>
Any idea how I can input those to the stream tracer?<br>
<br>
Minimal code like this is obviously not correct:<br>
<br>
<font face="Courier New, Courier, monospace">vtkStreamTracer
*streamTracer = vtkStreamTracer::New();<br>
streamTracer->SetInput(gridCellCenters->GetOutput());<br>
streamTracer->SetStartPosition(0.5,0.5,0.5);<br>
streamTracer->Update();</font><br>

<div>Here's a good place for an example if anyone knows how to do
