He folks.

I'm baaaaaack!!!

(Oh, what's that - no one noticed I was gone? *sigh* Oh well...)

Anyway, I've been wondering about something... I love lights on Christmas
trees. And my dad has more sets of lights than you can shake a VERY big
stick at!! I've been thinking about trying to simulate some with POVRay, but
I already know it's not going to be easy. The question is... Why do bright
lights have an "aura" around them? I mean, you can see a fairy lights from
quite a distance, considering how tiny they are. If I try and draw them with
POVRay they'll be smaller than a single pixel... but in the real world they
have a kind of "glare" around them which takes up more space and makes it
easier to see them from a distance (when they're lit!) Is there some
physical explaination for this?

Or do I just need to clean my glasses???

Thanks!
Andrew.
