Aha, got it!
My problem was that I was creating a NURBS mesh, then using the curve
extraction ('Curves') tool. This is great for proper curves, but not for sharp
edges.
What I *should* have done was to convert the mesh to NURBS curves ('ToCurves').
I'd forgotten that, by default, NURBS curves are invisible in photo-realistic
rendering. Setting each one to 'visible' solves the problem of obtaining a
wireframe image. To get uniform shading, simply add an ambient light source and
set the intensity to 1. (There are probably other ways to do this, but it's a
start.)
However, I'm still curious how to render a pure wireframe image in the same way
as the real-time rendering window.
Anyway, Neil and Jean-Sebastien, thanks for your help!
