Glowing water imagery ... how to? Got any thoughts?

Friends,

For yet another book cover (or the placeholder for it, as the book's nowhere near done as yet) I'm looking at ways to reproduce the effect seen in the image below. (It's of a photoluminescent "blue tide" in the Maldives.)

It's OK if the water further out from shore glows as well. But this shoreline look is gorgeous. Does anyone, just off the tops of their heads, have any thoughts as to where I might start in Terragen to try replicating this? (And hopefully improving on it.)

Thanks in advance for your time!

Well, you got the beach, don't you. I would just add some luminosity in a surface shader masked by the first few waves, perhaps masked by some PF for variation, some tiny PF (or tiny fake stone with no displacement as mask) as a base for shiny (reflective, or just more luminosity) pinpoints of light.

The beach was my first thought. Lovely thing that it is.

That said: the .tgd on that is complicated enough that I haven't been able as yet to figure out where to drop in that shader for the luminosity effect. Give me a day or two to puzzle over it and we'll see what I can come up with. :)

There is a tutorial on Ocean White Peaks that might be of some interest. Allows you take the displacement of the water and produce color from it which you could make luminous also.

Fleetwood, thanks for that! :) It looks useful.

I can see this weekend is going to be full of water tutorials...   :'(

And turn on Starburst set small and all that will pop like the pic...

Yes, good thinking on that. That should give it a bit of a nice sparkle.

Bobbystahr, thanks for the suggestion. I take it the starburst effect is in T4? I haven't upgraded as yet -- don't quite have the spare dosh at the moment -- but am looking forward to it, probably the end of this month after Black Friday and Cyber Monday have passed over our ebook store. :)

So here's a first attempt. It doesn't look much like the Maldives image, but that was just a pre-thought at what I'm presently aiming for.

A touch of backstory: I have this book series that I've been working on since 1979. I am finally starting serious work on the fourth and final book (if only because the emails from readers more or less shouting FINISH THIS SERIES BEFORE YOU DIE are starting to get annoyingly frequent. Or frequently annoying. Or both). The series includes a description of an afterlife or pre-afterlife experience described as "the Last Shore": it's a sea of light. I saw the Maldives image and thought "Hmm, that's a first step in that direction..."

I'm getting the new website for the series ready and realized I have no imagery to represent the last book (The Door Into Starlight). And needed some. So immediately my thoughts turned to Terragen. The book's final cover may not feature this imagery, but that's a different issue, for much later.

Anyway: a first attempt. To get it perfect is going to take much tweaking of the separate luminosity layers until the wave structure, even with the very counterintuitive lighting, looks right. But something like this (layered into a Daz3D foreground, because I need a doorway to be looking at this view through) will hold the space on the website for the moment...

You've got a good start there. For more pinpoints of light you could break it up by a small-sized fractal.

I think if you used the fake stone masking for the bright areas and use Boom and Starburst on the render it should give good effect. Check this out.
