Any one have seen the NVIDIA electricity demo. What is the trick behind such amazing effect? Thanks

I can''t tell you how all of it works...but I can make some guesses:

The electricity arc is probably done via a Purlin noise function(spelling ?)

The red spots on the plate are done using a very simple heat convetion model (I think that they just preset some values, then drop the heat to ambient over a period of time)

There is a significant amount of bump mapping done in it too - there''s an artical about that on the NV site
