The ASCII moon tool is fun to play around with!

No plans to build a library right now, but who knows. Feel free to grab what you need from the website's code!

If I were to build a library, I'd probably convert the shaders from WebGL 2 to WebGL 1 for better browser compatibility. Would also need to figure out a good API for the library.

One thing that a library would need to deal with is that the shape vector depends on the font family, so the user of the library would need to precompute the shape vectors with the input font family. The sampling circles, internal and external, would likely need to be positioned differently for different font families. It's not obvious to me how a user of the library would go about that. There'd probably need to be some tool for that (I have a script to generate the shape vectors with a hardcoded link to a font in the website repository).

I did actually try out various alphabets e.g. Cyrillic, Greek and symbols (e.g. box drawing symbols), but ended up removing them: https://github.com/alexharri/website/commit/d969ef839

Using only ASCII felt more in the "spirit" of the post and reduced scope (which is always good)

Looks very cool! Thanks for sharing.

The resulting ASCII looks dithered, with sequences like e.g. :-:-:-:-:. I'd guess that it's an intentional effect since a flat surface would naturally repeat the same character, right? Where does the dithering come from?

Just pushed a fix, should be live in a minute or two, thanks again!

Good catch, thanks! I’ll push a fix once I’m home

Yeah, this is good to point out. The primary constraint I was working around was "this needs to run at a smooth 60FPS on mobile devices" which limits the type and amount of work one can do on each frame.

I'd probably arrive at a very different solution if coming at this from a "you've got infinite compute resources, maximize quality" angle.

Author here. There isn't a library around this yet, but the source code for the blog is open source (MIT licensed): https://github.com/alexharri/website

The code for this post is all in PR #15 if you want to take a look.

Happy New Year from Reykjavík, Iceland!

Hmm, good idea. There are names that have the exact same pronunciation yet have different patterns of declension, for example:

- Ástvaldur -> ur,,i,ar - Baldur -> ur,ur,ri,urs

The "aldur" ending is pronounced in the exact same manner, but applying the declension pattern of "Ástvaldur" to "Baldur" would yield:

- Baldur - Bald - Baldi - Baldar

The three last forms feel very wrong (I asked my partner to verify and she cringed).

Spoken Icelandic is surprisingly close to its written form. I wouldn't expect very different results for the trie if a "phonetic" version of names and their endings were used instead of their written forms

It would be good to cover more names for sure -- that's an ongoing process at DIM. Names are frequently added to the approved list of Icelandic names, so there's always going to be some lag.

I would not be confident enough myself to add the data myself since I'd probably be wrong a lot of the time. When reviewing the results for the top 100 unknown names I frequently got results that I thought _might_ be wrong, but I wasn't sure. For those, I looked up similar names in DIM to verify, and often thought "huh, I would not have declined those names like this". For that reason, I rely on the DIM data as the source of truth since it's maintained by experts on the language.

As a native Icelandic speaker, I have an intuition for how to decline names -- I don't really think about it consciously. I'd assume that for most people it's just pattern matching.

Native speakers very frequently decline names in ways that are not technically perfect but sound correct enough. For example, my name (Alex) should not be declined, but people frequently use the declension pattern (Alex, Alex, Alexi, Alexar).

There's some parallel to be drawn with how the compressed trie applies patterns that it's learned to names. That's at least how I thought about it when designing the library.

Hmm, good point. I’m abroad this week and don’t have a laptop, but I’ll look at adding an MIT licence to the shader itself when I’m home. (I don’t want the post contents to be MIT licensed, but the website code and examples should be)

Thanks for raising this

Thanks a lot! Yeah tons of work went into this post, I’ve been working on it since November. The shader itself was about 2-3 weeks of evenings to get the effect 90% of the way
