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.
- achr2 2y agoThey mean distorted, not squished for both.
- SamBam 2y agoIt 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.
- inanutshellus 2y agoThis 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.
- JKCalhoun 2y agoYeah, I thought better (cleaner?) examples would have helped.
- morley 2y agoI wonder how hard it is to change a game engine to render images like this, and if the effect would be preserved while panning.
- svachalek 2y agoI think the difficulty comes from it being context dependent, it's not a consistent distortion of the true image the way most projections are, it identifies synthetic structures in the foreground and warps everything else (including similar structures in the background) around them. It should be possible for an AI filter though.
- stronglikedan 2y ago> The building at the right is not squashed ? It is wider than in the Piranesi picture above. The building on the right is squashed, in isolation. When you take the building by itself (in isolation), it is indeed wider than the picture above, but it is also the same height, i.e., squashed.
