When learning instrument flying and the first few night flights you learn to
always have at least two (I like three) flashlights handy. There's a company
in California that makes cockpit lights for some situations before you have
to resort to the flight kit for a flashlight. The version I've modelled here
allows the pilot to save his night vision by using variable voltage and a
red filter, as well as adjusting for a flood or spot light effect.

I just think they're cool just like everything else about airplanes!

Thanks, Shay (I think). Where do you see this as being chewed up?

Fascinating gizmo - I've learnt something!
For the imge quality, it wouldn't hurt to make the inner bore a smoother 
circle (looks like a polygon with about 10 degree steps). Antialiasing won't 
hurt the edges either.

Oh, I saw that as a mistake in 'error_bound.' With AutoCAD the mesh can be 
smoothed further by increasing the 'isolines' variable, which is really 
easy. I rendered this again with the new value for e_b and a doubling of the 
mesh density. I tested it with the same e_b value and a mesh four times as 
dense and the same effect could be seen, though reduced in severity.

Thanks for pointing that out.

You have done a good job modeling. Do the ones you use have a detachable 
base and power cord?

Thanks. The base can be relocated, or interchanged. The power cord is 
soldered to the bulb socket, so it can't really be removed except to service 
the light. I didn't model the cord, because it's a simple matter to create 
one should I ever use this in a cockpit scene (and you know I will). I will 
probably use the older method of a stiff-cord (sort of like one of Doctor 
Octopus' mechanical arms), if and when I do.

In AutoCAD the cord would be created with a circle swept (extruded) along a 
helix path and then unioned with other sweeps as needed. I'm sure there's 
probably a way to do that in Pov that would save on resources by comparison.
