Here's a simple network that demonstrates how the streamlines module can be used in SCIRun 4.  The lines are not represented as cylinders (like you had tried to do previously, but the resolution of the lines are turned up to 11 (6 is their default) so they appear thicker.  

Let me know if this answers your questions or just creates new ones.

Is there a simple network available for loading a vector field in the nrrd file format, seeding a specified location for streamline generation, then visualizing the result?

I've tried the following:

ReadField -> GetFieldNodes -> GenerateStreamLines -> ShowField -> ViewScene

However, there doesn't appear to be a way to specify a particular node for seeding, or a way to connect the nodes to the GenerateStreamLines module.

If you need any files from me to clarify an answer, please let me know.
