Just make sure the agent on the call on your behalf interrupts more.

Good point, re: the CA law. The rule for text output may be limited to the EU AI Act, which Anthropic notes as a reason in the linked article about its implementation.

As far as I can tell, this and the recent change to add watermarking to text outputs[1], is to become compliant with the EU AI Act[2] and CA's AI Transparency Act[3], SB-942[4]. For large enough companies, all generated AI content is required to have watermarking.

I guess the fact we see any at all given the distance and small angles just emphasizes how many there are out there...

Oh nice, I had not zoomed out enough. I don't think I've seen the relativistic jets rendered before. The AR mode looks great on my phone.
Yep, I had fun learning a lot about punchcards, Fortran, and the math behind black holes. I suspect I'm doing something similar to you in my Fortran implementation, raymarching along the null geodesic to come up with my final image: https://imgur.com/a/czysDls
Also, I have to point out the "going full circle" pun, intended or not.

I think the contrast between the two sides is typically greater with an optically thick disk, and it looks like you are rendering an optically thin disk. I think that's the main difference from what I was expecting when I saw it.
Very cool demo! Thanks for sharing!
(For reference, my experience rendering black holes is recreating Luminet's rendering from the late 70s: https://www.ioccc.org/2025/cesmoak/index.html )

Please correct me if I'm wrong, but it feels like the leading edge of the accretion disk (coming towards the viewer) should be significantly brighter than it is shown here, and the trailing edge (going away from) should be significantly dimmer?
Or could the brightness shown be a result of it being Kerr vs Schwarzschild?

Interesting choice to build in Greensboro. That's also where Boom chose to build a factory and it looks massive as you leave the airport. The plan for this company's factory looks like it will be significantly larger.

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.
