I'm just enthralled with your water. It is *so* inspiring, and presents (to
me) a *new level* of the power of POV-Ray.
I've been doing a great deal of isosurface experimentation lately, learning
lots of new things, and there might be a way to alter those crests. The idea
involves "fading" one isosurface function into another, over a certain
distance.
What I'm thinking is this:
Fading in an f_noise3d function in the +y-direction, somewhere near the top
of the crests--to actually break them up with "bits" of tiny noise blobs, to
simulate spray. I *think* (but am not sure) that your water-wave function(s)
could be used IN the noise function, to actually vary the height at which
the noise comes into play (so that the noise doesn't just show up at a set
y-height.) I've gotten this trick to work on some isosurfaces of my
own...though not of the complexity of your waves.
My ideas are a bit tricky mathematically...and difficult to explain...but I
now have a methodology of sorts that seems to work, and that "makes sense"
to me.
I'll definitely take a look at your code--which I'm absolutely overjoyed
that you've posted--and see if I can do what I've mentioned. If successful,
I'll post an image.
Meanwhile, I'll work up a simple --VERY simple!--demonstration code example
(or two) and post it here.
