I remember being quite blown away as a 20 year old during a trip to Paris by some of the paintings in the Louvre and the Musée d'Orsay. I had known many of these paintings before, from Wikipedia and school books, but it seems to be impossible to capture the effect of an oil painting in a digital or reproduced image, because, as the article describes, an oil painting is essentially 3-dimensional.

And yet, it's the postal stamp-sized Mona Lisa that gets all the attention... Sure, it's a good painting, but I p…

How is this relevant or an interesting point? Tourism is tourism. Mona Lisa is famous.

It's not impossible, computers have been modeling 3D fluids for a long time. It might be computationally intensive, but definitely not impossible.

He's talking about reproduction, not modeling. You can model the painting's physics all you want, you still won't be able to make a faithful reproduction on a flat and gamut-limited LCD screen.

I'm noticing an increasing amount of rude comments on HN these days. Please, keep it civil.

With head tracking it should be possible to get close. The thickness changes are small, so the 3D effect is mostly from the uneven light reflection revealed by head movement, not stereopsis.

No it's not, as the author says in the 3rd sentence of the article. Watercolor paint is not an adhesive in any sense of the word. And there are plenty of paints which also dry, leaving a powder behind that can easily rub off. So yeah, some paint is glue, some is not.

At least the abstract is more precise: > The secret of oil paint, as mastered by our greatest artists Nevertheless, an interesting read.

The 4th sentence is about watercolor paint:

>Watercolor paint does it by drying, releasing water into the air through evaporation and leaving only the pigments on the page.

This is not glue.

The painting opposite of Mona Lisa is the The Wedding at Cana. It's one of the most impressive paintings in Louvre (I think it's the largest). I have wondered if they placed it there as a joke.

There is over 100 people in the painting being busy and only person looking outward directly towards Mona Lisa is Jesus looking surprised. Mona Lisa is looking directly at Jesus and smirks.

Interesting. I wish they hadn't thrown in this nonsense though:

> It's exactly the intricate expressiveness of oil paint that made Renaissance art so sensual and passionate
