@FabMusacchio Hello! Can I ask where the url shortener sends?

@mathieu_ @AudeCaussarieu
Ça, ça marchera jusqu'à ce que les IA génératives d'images se mettent à placer les éléments d'une image dans un espace en 3D.@Mourioche
Évidemment, ça me semble temporaire comme erreur.

@ilusenn @FabMusacchio It's legit - the website of the scientific journal, Science (they picked scim.ag because it is short for Science magazine).

@JonnyT @FabMusacchio Thank you!
I try to keep the habit to ask everytime

@JonnyT Thanks! For I never click on URL shorteners ... like many people here. @ilusenn @FabMusacchio

@FabMusacchio good post

@NatureMC @ilusenn @FabMusacchio Definitely not a fan either but I am aware of where this one leads (or, at least, should).

@AudeCaussarieu@mathieu_ @AudeCaussarieu Je mets ma main au feu que les IA génératives savent déjà le faire, si on leur demande dans le prompt
On va surement en arriver au même résultat que pour la presse ou la télévision : La confiance dans le média sera lié à la réputation du média et à rien d'autre...

@FabMusacchio beautiful analysis even though I'm still suspicious of lens distortions.
@f4grx @FabMusacchio sun rays are parallel, yet they meet at a point...?

@Deixis9 what's the origin of the image?
Thanks
I see that it's commercialised e.g. <https://lovingsquad.com/product/ai-slop-is-not-art-chatbots-are-not-your-friends-shirt/>, <https://pagtee.com/product/t-shirt/1926944-ai-slop-is-not-art-chatbots-are-not-your-friends-cyborg-painting-flames>, <https://zerevia.com/product/t-shirt/1926944-ai-slop-is-not-art-chatbots-are-not-your-friends-cyborg-painting-flames>, <https://www.spellingmistakescostlives.com/product-page/copy-of-ai-slop-is-not-art-chatbots-are-not-your-friends-sticker>, however there's no real acknowledgement of an original artist; no credit, as far as I can tell.

@leah @f4grx @FabMusacchio they meet at such a far away point that they appear to be parallel
-
@FabMusacchio So if I want to commit a murder, I have years to prepare it and I know the place will be surveilled with cameras, I should pave it with slightly non-parallell tiles, to get a plausible deniability.
@microblogc @FabMusacchio Forced perspective is your friend: "The Potemkin Stairs in Odesa extend for 142 metres, but give the illusion of greater depth since the stairs are wider at the bottom than at the top."

@leah @f4grx @FabMusacchio they meet at such a far away point that they appear to be parallel
@nCrazed @f4grx @FabMusacchio But this is irrelevant for the technique described? It would work with a non-parallel spot lamp just as well?
-

@leah @f4grx @FabMusacchio yeah, I think that's a fair criticism

@leah @f4grx @FabMusacchio yeah, I think that's a fair criticism
@nCrazed @leah @f4grx @FabMusacchio Lines from a shadow through the object casting it meet at the light source. Sunlight being virtually parallel is irrelevant. If the light source isn't point-like, you get blurry shadows.

@nCrazed @leah @f4grx @FabMusacchio If the light source is behind the image plane, these lines will of course converge at an opposite point. The important part is that they all converge. If they intersect every which way, something funny is going on.

@FabMusacchio Great to have a sure way to prove things, but honestly, just zoom in on details see if they're coherent? In most if not any genai image? Not even talking about the dinausore/crocodile one because if you're under 50 you could tell in one blink
