Jacuzzi effect?

Pikadili89 · Post by **Pikadili89** » Fri Dec 12, 2014 11:45 pm

Hey guys, the title says it all!

I need to do Spa center and ofc it needs to have jacuzzi. So my question is, how can I make or at least fake jacuzzi effect? Have anyone tried something like this before? I tried searching forums but found nothing helpfull

This is what I want to do and curently I failed every time with displacment maps. Anyone have any idea?

Thanks in advance!

Yes, seems not that easy...
My approach would be:

- Use a glossy Transparent material with photo a texture of such a jacuzzi water to control the exponent of the material.
- Use the same but a little blurred texture for displacement!
- Now use the texture to control the color too.

The exponent map needs quite some strong contrasts I suggest.
SSS is maybe even not needed here

Depending on how accurately you want to model it, you could try blending a diffuse white material with the water specular material, with a blend map that looks like the 'bubble waves'.

hi, this is one effect I was willing to synthetise with ISL, I may be back to you soon. do not hesitate in bumping this up if I am lasting about it.

Well, don't let me hold you back on this one, my first results were quite limited. I'll try to have them uploaded tomorrow even though I'm unhappy about them. They figure jet convection sort of, not bubbles. Crappy. Ouch :/ Tomorrow hopefully.

here, I thought I'd take a shot at this. it's basically Ono's suggested approach with blend of specular and diffuse.
the scale of displacement needs tweaking depending on your scene scale. plus the texture values for blend and displacement will depend a lot on the images you are going to use.

I also used one material for the top of the water cylinder (bubbly blend) and for the sides and bottom (plain water with blue-green color), those both have to share the same medium.

this would probably benefit a lot with the photon-mapping methods that are in the works too, cause the water parts take a while to clear up and are pretty dark.

anyway, something to play around with and get you started. it's a pretty cool challenge.

awesome, up to the MatDB!

thanks!
here, it works much better with simple color absorption in the medium instead of absorption layer with an image texture. also made the bubbles a uniform color phong instead of image color.

oh wow fakeshamus... this is one instance where I should have hold my horses back but I must now comply and post a lame thing. I meant what I said and I... grrrr

good job.

The treat is, in the bump shader you can try 4x3 combinations for a result, just move the # signs around.

Hello guys, first of all I want to apologise for my so late respond. During my strugle with jacuzzi effect I sudenly got a new task from my boss and I needed to pause the spa interior project. Today I finish spa interior and I decided to share with you both of my works. That suden task was interior design of catering apartment in vila, the interior was desired as light classic. And I am happy to tell you that it is accepted by investor. As for spa center, it is existing building which demands heavy reconstruction. Interior was desired to be luxorius and modern.
In this comment I am uploading catering aparment in vila, in second, I will upload spa center.

And ofcourse, I owe a big THANKS to FakeShamus for sharing this awsome material! Thank you mate!

c&c are welcome as always! Hope you'll enjoy!
