If the river was made of whiskey and I was a duck...I'd swim to the bottom and never come up!

That better be Jefferson's Ocean Whiskey, specifically.

What does generative mean?

Hmm, an Islay I'd imagine.

hmm ok, why not, let me try... its basically "ray tracing/ray marching/path tracing": first i'm defining the glass and the whiskey surfaces as mathematical functions (actually distance appoximation functions). then for each pixel i step from eye position into the direction of the pixel into scene until i hit a surface. on a surface with a certain probability (fresnel equations) the viewing ray gets reflected/refracted from the surface and walks along. this is repeated until the ray hits a light source. and this is then repeated for all pixels and several times util we have a properly lighted scene...

Nice pic. Kind of brings to mind the German saying "Ein Sturm im Wasserglas" (A storm in a glass of water), which is used if an event/problem/thing ends up way smaller than predicted/feared.

I thought it was one of those cool ecosystem jars for a second

What's fascinating is how you modeled the whiskey waves... it even has foam ! What mathematical function looks like waves ? Not the ones I studied at school x)

Mod here. OP's own statement on what "generative" means:

> ... its basically "ray tracing/ray marching/path tracing": first i'm defining the glass and the whiskey surfaces as mathematical functions (actually distance appoximation functions). then for each pixel i step from eye position into the direction of the pixel into scene until i hit a surface. on a surface with a certain probability (fresnel equations) the viewing ray gets reflected/refracted from the surface and walks along. this is repeated until the ray hits a light source. and this is then repeated for all pixels and several times util we have a properly lighted scene...

The easy way to defuse suspicions in cases like this is to show a post history of similar content, which OP has. So I'm going to assume that

  1. This is not "AI", it's a mathematical render to create a particular image, and
  2. OP wrote or at least contributed to the software, so it's fine.

For those taking notes, this is how you do it. For those claiming to have written their own AI, show proof or GTFO.

If the ocean were whiskey... Yes, I am that old.

the functions are just the ones from school, just many of them summed up and in different scales ;-)

oh, and the foam is actually an illusion. in thin layers (like in the wave crowns) the light gets reflected/refracted multiple times in the same region, which leads to a more random light diffusion in those regions. i was surprised myself by that effect! ...that doesn't mean real waves cannot have foam additionally ;-)

I usually dislike a lot of the stuff here because it feels cheap(my taste of art is my own) and I actually really enjoy this. The color pallet and the emphasis on the motion inside the cup but still outside is some very powerful imagery for me.

Viewing this, I saw the noise patterns and thought it looked like a render, and then was wondering how AI generated images would make such perfect reflections underneath the glass.

Being raymarch/raytrace made a lot more sense. What kind of timeframe does a single render of this take? Is this like a one minute or one hour kind of thing?

I was about to comment on the beautiful lighting, makes perfect sense seeing the raytracing comment. I'm always amazed at using stuff like programming to create artwork like this. Great job!
