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.
