Piranesi's imaginary prisons are worth a viewing. Great gothic prisons from a fever dream rendered in a similar fashion to these engravings.

#12In 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.
This was a really cool article and I hope others read it through, but yes, it took me way too far into the article to "get" what he was saying was wrong with the perspective.

#13I'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.

#14> 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 of this, it tends to make everything equally detailed.

Hmmm

If so then surely a program could be written

I second this review - Piranesi is a fantastic and inventive novel.

#19Surely this introduces some curvature to the diagonals? I can't see how the perpendicular lines can be in correct perspective with the diagonals being parallel unless something is curving. I guess because it's preserving the perpendicular lines and the curvature is subtle, it's not very noticeable in typical architectural pictures.

Something is up with that green building on the right, too. It's wider in the "true perspective" views, wider even than the ortho view
