For those just learning about perceptual colour spaces, I’d recommend exploring OKLab which is simpler to implement and overcomes some of the problems of CIELab.
Still going through the article but loving all the detail and interactive components! Nice writeup.
PS: worth mentioning the RGB to CMYK function credited to me is not my original work, I believe I got it off stack overflow or similar many years ago. A more robust way of doing this transformation would be with a color management system and profile, as it happens I’ve done a bit of work on that! [1] Used this here [2].
Transforming with ICC profile will give you a result that might be closer to how a screen printer would turn your digital image into a four colour print, but more advanced screen printing workflows these days tend to use “rip” software that handles many layers (eg: 12 colors instead of 4) and stochastic screening [3] which produces quite different results than what most halftone shaders are doing.
Nice work, the outputs look ethereal and quite beautiful. For some related work using genetic algorithms and evolution strategies, see[1].
Sketch synthesis is an area I'm pretty interested in lately; I'm currently exploring similar things with CLIP to guide fitness, natural evolution strategy to optimize the rendered results, and using an implicit neural representation to represent pen plotter paths (rather than a series of explicit curves/strokes).[2]
Amazing as always, Bruno is a wizard with ThreeJS.
There’s a surprising amount of stutter and lag on iOS, evident after the loading bar completes and the app freezes for 30 sec. Also during gameplay, quite a bit of stuttering. My guess is GPU texture uploads or shader compilations. Otherwise it was buttery smooth.
A similar thing happens when you search “Canada eTA” — a $7 (required) entry visa the government typically issues instantly. But on Google, several sponsored sites appear above the gov site, and charge $100+ for the same service but slower, and they do god knows what with your passport details and personal data.
There are tons of other examples like this. It’s very easy to get tricked by Google ads if you aren’t suspecting a scam.
In Sweden they sell bucketloads of saffron for basically a euro or two per pack. The equivalent in UK stores would have a 10x markup at least. It seems like an industry that somebody could easily capitalize on, unless there is some trade or monopoly restrictions we don’t know about.
USDC hasn't collapsed, and it never should (or at least, no more than any other financial services you use daily) if it is properly regulated by US enforcement agencies.
USDC + L2 would be a suitable protocol for day-to-day purchases and nearly 0% fee, at least for those already in the system. But most of this tech is still basically in beta.
Last month's OpenSea volume was $2.4B, the volume so far for the first nine days of April is $1B.[1] The average volume over the last few months is somewhere around $3B. Certainly the monthly volume and overall interest will rise and fall as all markets do, but total usage over time seems to be growing, and also expanding outside of OpenSea into other chains, protocols, apps (eg: Tezos).
