There are a few "wait what?" moments in the first half of the book that no other books have matched.

Sadly, the ending doesnt live up to the expectations, at least for me.

The paradox of mystery, when the mystery is too good that no ending can justify it.

A very different book, but I loved reading "Jonathan Strange & Mr Norrell" [0] as well by the same author. [0] which used footnotes to great effect

This also has a great audiobook version. Simon Prebble really brings the characters to life.

Indeed. It made long walks with my dog seem all too short.

> rather we ignore the blurry parts unless we specifically try to notice them, and anything we try to focus on becomes sharp. Unrelated to perspective: Artists often put more detail in places that you're "supposed to" look at, and leave other things more as a blurry sketch, and our eyes naturally don't linger on those parts. What's interesting to me is that I can often recognize AI art by the way it doesn't make use…

One of the most dramatic things in this respect is to look at a photograph of a flame. Our lived experience of what flames look like is very different. The same is true of nearly any dynamic object in life (flowing water is another great example where the photograph doesn’t look like what we experience).

Those examples are very challenging because they are volumetric objects, in addition to being dynamic. The flame does not even have a well-defined surface. What you see as red/yellow in the flame is in fact just glowing soot particles, and the point where this disappears is just a temperature difference in the gas such that the soot stops glowing.

I remember being very frustrated with the main character while listening to the audio book. I enjoy the memory of the story a lot more than I remember actively listening to the story. I think I kept trying to "figure out" the world like it was a puzzle. I also find naive characters very frustrating. It wasn't until I finished the story that I really appreciated it.

"The House is valuable because it is the House. It is enough in and of itself."

So did you just spoil the ending for me?

> By legibility I mean that the Piranesi distortion is easier to read, and that to anyone unfamiliar with photographs, that hasn’t grown up with TV, photographs and magazines, the Piranesi version would look much better, and the true perspective would look rather odd. I think this is a key point that people are often unaware of. For instance, whenever I see a modern artist who has painted photorealistic art, I read d…

One of my favorite books is "Seeing Like a State"[1], which talks about how the modern world has transitioned from talking about things like distance and space in human terms ("an hour's walk", "six bushels' worth of crops") to a surveyor's terms ("3 miles", "5 acres"). In the modern world, we're very used to thinking about things as mediated by technology (maps, cameras, compasses), and that affects how we think about arts, as well - matching what a camera produces is "photorealistic", but isn't how we actually _see_ things. This is one example, another I've always found fascinating is that the large Chinese landscape paintings play a trick where the perspective shifts depending on where you're looking - the whole work does not share a single perspective point, but any given point on the scroll looks "correct" for that spot and its surroundings.

Here is the Panini projection paper, it's a good read[0].

Unreal Engine has support for it as a post-processing filter[1], but I don't know of any games using it.
