Need a shader example for pool water

I am attaching a pool I just saw in a 3d illustration.

How can I create that with arnold?

Should I apply a noise bump map but scaled to seem linear?

thanks for any help....

I've faked it with an area light with an image texture and the spread set very low.

@Shawn Kearney

Maybe this is the solution, but I have to try it...

Since then, this is what I can archive with my arnold

knowledge... (and... I am not satisfied...)

Have you tried a Gobo? I would use displacement rather than a bump for realism.

It's not a pool, but some of the techniques used here might also be relevant.

Thank you both for inspiring me to take a deeper

look at Arnold's features.

I wish I could accept both your answers as solution.

So my purpose was to create sunlight rippling patterns,

to create a nice realistic surface like the picture I attached

before.

Shawn: yes I have to fake it with an appropriate water pool texture.

Sure using a gobo modifier with a spotlight, it will create that

effect over the whole water volume. But for the moment because

I have no time to experiment that, I just used this texture as

a simple bitmap on a standard surface material.

Lee: yes the displacement map was the key for realism. I used a noise as vector map (as I saw in the ocean example you showed me)

So for the moment, this is what I get and I am very satisfied. In the future I will sure evolve my tecnique.

Thank you guys.
