CIRCLE WITH A DOT

@thomastc Ah, fair enough. Perhaps just sampling a handful of times over a wide area would be enough? The further apart the samples, the less effect any small discontinuities would have, and it's not like you really care to capture any significant detail

@thomastc Nice work! I think a solution probably looks like taking the dot product of the wind vector and the terrain gradient and using that to determine wave amplitude. Awesome stuff
