Hello,<div>I think the problem is your dataset has no cell, just points, hence Glyph generation works well because it consists in drawing a glyph at a subset or every point.</div><div>But computing streamlines requires compute trajectories, ie to evaluate the flow at arbitrary points.</div><div>this is achieved by interpolation within cells and if there is no cell, no interpolation scheme exists.</div><div>So my advice: compute a tetrahedralization of your point cloud so as to create a valid unstructured point dataset and it should work well.</div><div>Regards<br><br><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">Date: Fri, 13 Jan 2012 13:27:10 +0100<br>From: Arnox1111@web.de<br>To: paraview@paraview.org<br>Subject: [Paraview] Problem applying StreamTracer Filter<br><br>

Hello everyone,<br>
<br>
I am trying to visualize my Data with Paraview 3.12.0 by exporting
velocity vectors to an unstructured grid that is saved as a xml vtu
file. So far the Glyph representation worked out great, but I
couldn't get the streamtracer to work with my data. I directly
applied it to the vectors, but there where no lines with all
parameters I've tried.<br>
I've attached an example of the data. <br>
Could someone please point out my mistake?<br>
<br>
Thanks for looking into this.<br>
<br>
Cheers, <br>
Arne<br>
