In the image with the caption: "Normal homography perspective transformation produced in GIMP. Note how squashed the buildings at the right and left are when taken in isolation" The building at the right is not squashed ? It is wider than in the Piranesi picture above.

It would have been nice to show a few more easy-to-understand comparisons. The "street view" image was nice, but blurry. Ditto with the map. I think if the last image of the two buildings had been shown side-by-side with the "correct" perspective, that might have helped explain the article.

I wonder how hard it is to change a game engine to render images like this, and if the effect would be preserved while panning.

I'll take this opportunity to drop the fact that I'm kind of obsessed with the book "Piranesi", where the main character (named after the artist in the article) survives in a world which is just endless corridors of classical architecture, statues, and staircases. It's an incredibly calming experience, I've listened to the audiobook over 10 times before sleep. Highly recommended.

A truly wonderful novel that I also opened the comments to shill.

> 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…

> 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).

This must have been the inspiration for the Counter-Strike map de_piranesi !

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.

Doing it with a camera/computer requires identifying the objects that need to be drawn in "Piranesi Perspective". The mathematics of laying out the objects is quite simple, but rendering a raster image into a view such that the key objects have this perspective probably isn't possible. You would need to vectorize the image in a general way. I don't know the state of the art in that field, but it sure seems hard.

No, the CS map predates the novel by almost 20 years. Almost certainly they were just both inspired by the same artist.

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.
