I can now see the problem (actually multiple problems). The first problem is that the spacing in the Z direction is a negative value. That is apparently not really supported and I'm seeing some screwy behavior based on that. Changing the spacing values to be all positive numbers fixes that problem.
The second issue I see is that the streamline filter is not working properly on 2D images that are defined in the x-z plane (as yours is). That's a bug in ParaView and I've submitted a bug report (http://www.paraview.org/Bug/view.php?id=7787). You can get around the problem by either defining your images in the x-y plane or by converting to an unstructured type (either Clean to Grid or Extract Surface will work) and run the streamline filter on that. -Ken On 10/7/08 12:09 AM, "Hom Nath Gharti" <[EMAIL PROTECTED]> wrote: > Thanks.
