<pre wrap="">Have you tried using sphere_sweep with b_spline or cubic_spline for
your
wires? You set some control points and the sphere sweeps smoothly from
one to the other. You need 2 extra, purely controll, points, one at each
end of the sweep, and you can have as many other points as you want.

Not sure how to begin with it.
Sparks are a bit "jaggy", and of course very bright.
I also have to solve the problem of wires, which do smooth (and complicated)
curves.

sphere_sweep with b_spline for the wires. This enable you to do very
complicated and smooth 3D curves. An example of a sphere_sweep using
b_spline interpolation. A total of 34 random points were used.<br>

You want a or some electric sparks going from one knob to the other,
you can use some emissive media with a good amount of turbulence. Have
a sharp color_map blue-white in the middle, clear everywhere else,
turbulent cylindrical pattern, add some other small dimer tighter media
to do some forking. Render using radiosity and the sparks will light up
your cene.<br>
