Have been talking with a friend about simulating and rendering electricity for some other projects recently. I encountered a self-contained paper (http://www.cs.unc.edu/~geom/LIGHTNING/lightning.pdf) on the subject and spent a little time this evening hacking up a quick implementation of the simulating a bolt. It's way simpler than I expected, and gives me one more reason to be glad (yes I'm glad) I'm friends, I'm friends, with the Laplace/Poisson equations.
Anyhow, a crappy rendering using a coarse grid (no tracing lines, or anything fancy), blurred and combined with the gimp. I guess blogger doesn't like the gif I uploaded, so this entire post was a waste.
