Following on from my previous Flow Map post, I wanted to see what flow maps would look like with maps generated in real time using a fluid sim.

Using the well known GPU Gems fluid sim article and a ShaderToy implmentation as reference I added my flow map shader over the top and got this result.

It came out better then I expected, especially considering the Jacobi solver is only run once! (rather then the 20+ time suggested in the article).

The next step may be to write a WebGL version and try some more stylised water rendering.
