this reminds me of Polyworld by Larry Yaeger, an artifical life sim where each creature has a vision system. i played around with this back in the early 2000s though the hardware i had access to was basically insufficient to run it in any real way. it's nice to see its development has continued.
whenever i hear about a Cray, i'm always reminded of the scene in the movie Sneakers where they sit on one to have a conversation
i made some art on this site years ago. some people used this to make plottable art. plotting it is definitely a slower way to watch it work through a drawing :)
turtletoy was made back around 2018 before web assembly was generally available.
you can download each as an SVG and then render it out at any resolution using something like inkscape
The main benefit I see is being able to more accurately represent different light sources. This applies to transmission but also reflectance.
sRGB and P3, what most displays show, by definition use the D65 illuminant, which approximates "midday sunlight in northern europe." So, when you render something indoors, either you are changing the RGB of the materials or the emissive RGB of the light source, or tonemapping the result, all of which can approximate other light sources to some extent. Spectral rendering allows you to better approximate these other light sources.
The only applications I'm aware of that currently do spectral rendering on the fly are painting apps.
I have one called Brushwork ( https://brushworkvr.com ) that upsamples RGB from 3 to a larger number of samples spread across visible light, mixes paint in the upsampled space, and then downsamples for rendering (the upsampling approach that app uses is from Scott Burns http://scottburns.us/color-science-projects/ ). FocalPaint on iOS does something similar ( https://apps.apple.com/us/app/focalpaint/id1532688085 ).
I'm happy that tech like this will open up more apps to use spectral rendering.
i would expect the more dense part to be the smaller gamut that can be made with paint since we've been naming those colors for a lot longer than the larger gamut that can be made with a screen. The paint/print gamut looks kinda like the more dense parts of these scatter plots within the larger sRGB cube (though the paint gamut isn't entirely contained within sRGB).
there is a cool project that explores this topic: https://coolcolors.lbl.gov/
dreams on playstation and unbound on pc both use sdfs to allow users to make truly round objects for games
diffraction grating wouldnt give you a controlled lighting environment (illuminant). they seem to handle that issue here by using a known spectral reference chart which might let them handle any normal lighting environment.
i lived about a half mile from this house in the same neighborhood -- it could be a lot more expensive if it had the view some properties around there have.
note that mulholland dr is just up the street from the house. this overlook is worth a visit: https://maps.app.goo.gl/muMirzaSJsEt9YnR7

diaspora by greg egan is a good example
sliding scale of other liquors of varying subjective quality
the bar Little Brother in Austin has a fun deal. for $5, you roll a d20 and if you get a 20 you get a shot of whistle pig. anything 1-5 and you get a shot of malort.
The speed limit went up to 85 in Texas. It seemed to max out at 75 or 80 in other places. I'm not sure if an extra 5-10mph made the difference, but it could have.
How do you look at spamming private messages to many recipients, resulting in a similar effect to posting publicly?
I know of bullying on FB where the harasser sends the same message to dozens of friends of the harassed. FB makes this easy to do since a list of someone's contacts are often easy to find online and there is no recourse to find or report these messages (as with a public post).
To me this presents a particularly tricky double-edged sword. E2E encryption is good in many cases, but tied to an easy way to send many messages and easily-accessible lists of people to target a message to, can result in a similar but more hidden version of public posts.
My guess is that this is being used today to disseminate similar content that is being restricted on public posts.
As far as I can tell, restrictions to limit the number and speed of private messages have not been effective against this kind of approach, and new accounts can always be created. In some cases, these messages go to a different "inbox" for non-contacts, but not always, and this just delays the receipt of the message since, again, they cannot be found or reported.
I don't know a good solution to this problem, but it's not one I've seen talked about.
I just drove across the US (down the east coast, across the south, up the Rockies) and found I had to do this only after driving across Texas.
In Windows Explorer, if you click to the right of the breadcrumbs, you will get a text input with the full path to the current directory. If a solution for URLs were to attempt to switch to breadcrumbs (seems like it should be site-configurable via a meta tag or something), then a similar click to the right of the breadcrumbs could expose the underlying URL.
Yes. Here's a video that describes an approach using neural networks to estimate physics instead of using a traditional simulation: https://www.youtube.com/watch?v=atcKO15YVD8
If you are interested in exploring a world where something like what you suggest is a generally-accepted part of life, check out the book Super Sad True Love Story. http://supersadtruelovestory.com/
This novel is set in a world that takes current social and sharing trends and extrapolates out a dozen years or so. Depending on your thinking, it could be seen as an extreme or a reasonable guess of what might happen in the future.
there was a brief outage at the hurricane electric datacenter in fremont, probably due to the storm that came through the bay area this evening. our servers (not part of linode) went down, too, but were back up a couple minutes later. i can't confirm the cause, though, b/c i can't reach anyone at he.net on the phone. =(
