Coastal waves/foam thru functions?

[Dune]

That is amazing, Jon. Congratulations on your job! I've been at it for a while as well, but my math won't stand up to yours. I only found a way to get 'ridged' waves following the coast, which can be blended with the normal sinus, but the curling is still done by twist and shear shader, and only possible into one direction, i.e. local.
Perhaps your method can be implemented in the software itself in due time, would be great!

Wow...I'm gob smacked by this...too beautiful and a few tweaks away from real waves...way t' go mate.. ...

Thanks guys, but I don't think I've cracked it yet. There's another 400frm animation to upload as soon as Vimeo sorts itself out.

I wanted to see where and how the PFs will fall down, it's a fine line getting the movement to variation, and when I can get the latest rendering up, you'll see what I'm talking about.

Even so, I've got some more ideas which should address some of the problems.

Looks very realistic first, and then nature starts to freak out 

Very impresive !

Brilliant work I have a hard time getting any foam on my ocean surface at all, you seem to pretty much have it mastered hehe.

[Hetzen]

Lol at microwar, you're not wrong. Things go a little hectic towards the end.....

heh, yes towards the end looks a little unrealistic- but that kind of stuff could work for very turbulent water, like stormy seas, etc. It's like wind action.

every 7th wave....  Great work

every 7th wave....  Great work

I kind of got the syntax wrong on that, it should be the height of the wave, is one 7th of the wave frequency. (on average, and yes, waves do compress when you consider back draw (?)).

The above was just playing around with PFs, so it was a finger in the air on the look. What this won't do atm is follow coastal relief, which is possible with Dune's approach. Using sine waves will eliminate the need to use get normal to displace by, which is a big ask to displace something then to have the program to look at the slope direction on rendereing to influence the previous displacment. Which is why there's popping geometry.

I admire your tenacity in attempting this.  You are both approaching something worth while methinks.

very interesting and impressive!

Wow. This is really incredible work! 

[Hetzen]

We've got a new tool.

Looking forward to jumping back on this.

Wow Hetzen.  Thanks for the shock and encouragement.
