I like “veridical” mildly better for a few reasons, more about pedagogy than anything else.
That’s a fine set of reasons! I’ll continue to use “accurate” in my head, as I already fully feel that the accuracy of a map depends on which territory you’re choosing for it to represent. (And a map can accurately represent multiple territories, as happens a lot with mathematical maps.)
Another reason is I’m trying hard to push for a two-argument usage
Do you see the Spinning Dancer going clockwise? Sorry, that’s not a veridical model of the real-world thing you’re looking at.
My point is that:
The 3D spinning dancer in your intuitive model is a veridical map of something 3D. I’m confident that the 3D thing is a 3D graphical model which was silhouetted after the fact (see below), but even if it was drawn by hand, the 3D thing was a stunningly accurate 3D model of a dancer in the artist’s mind.
That 3D thing is the obvious territory for the map to represent.
It feels disingenuous to say “sorry, that’s not a veridical map of [something other than the territory map obviously represents]”.
So I guess it’s mostly the word “sorry” that I disagree with!
By “the real-world thing you’re looking at”, you mean the image on your monitor, right? There are some other ways one’s intuitive model doesn’t veridically represent that such as the fact that, unlike other objects in the room, it’s flashing off and on at 60 times per second, has a weirdly spiky color spectrum, and (assuming an LCD screen) consists entirely of circularly polarized light.
It was made by a graphic artist. I’m not sure their exact technique, but it seems at least plausible to me that they never actually created a 3D model.
This is a side track, but I’m very confident a 3D model was involved. Plenty of people can draw a photorealistic silhouette. The thing I think is difficult is drawing 100+ silhouettes that match each other perfectly and have consistent rotation. (The GIF only has 34 frames, but the original video is much smoother.) Even if technically possible, it would be much easier to make one 3D model and have the computer rotate it. Annnd, if you look at Nobuyuki Kayahara’s website, his talent seems more on the side of mathematics and visualization than photo-realistic drawing, so my guess is that he used an existing 3D model for the dancer (possibly hand-posed).

Yup, or as I wrote: “2D pattern of changing pixels on a flat screen”.

For what it’s worth, even if that’s true, it’s still at least possible that we could view both the 3D model and the full source code, and yet still not have an answer to whether it’s spinning clockwise or counterclockwise. E.g. perhaps you could look at the source code and say “this code is rotating the model counterclockwise and rendering it from the +z direction”, or you could say “this code is rotating the model clockwise and rendering it from the -z direction”, with both interpretations matching the source code equally well. Or something like that. That’s not necessarily the case, just possible, I think. I’ve never coded in Flash, so I wouldn’t know for sure. Yeah this is definitely a side track. :)
Excellent. Sorry for thinking you were saying something you weren’t!

More simply (and quite possibly true), Nobuyuki Kayahara rendered it spinning either clockwise or counterclockwise, lost the source, and has since forgotten which way it was going.

I think we’re in agreement on everything.

Nice find with the website, thanks.
