Here is the obj that I'm trying to render (they represent charged particles) https://www.dropbox.com/s/e3w87d38pqizjzr/event000000000-tracks.obj?dl=0
Edit: just to be clear, these aren't arbitrary curved lines - they represent the output of a physics simulation so I need to render EXACTLY these lines.
Using the internal renderer I can chose the 'wire' material and this looks great. However the detector itself looks very messy with 'internal' and so I would prefer to use cycles, and here I'm completely stuck. This is NOT the wireframe view of a solid object - it's really just a bunch of lines and I just cannot work out how to get them to appear. Any hints?
For reference, I want to produce something similar to :
