> Bjarne has been criticized for accepting too many (questionable) things

He even writes that way in his own article... The quote from the last section of the introduction was hilarious, and actually made me laugh a little bit for almost those exact reasons.

Not sure if this is the creator of the Github project, yet one improvement would be view frustrum culling.

Registers 700,000 triangles even when there's nothing visible on-screen, just because the Stanford rabbits happen to be nearby in terms of LOD.

Even something "simplistic", like LOD quadtree culling with a view frustrum would probably dramatically reduce triangle counts and speed up rending even further.

That said, still an impressive demo, and compared to what I often see done with three.js, really fast rendering speeds for the sheer quantity of instanced geometry being shown.

On pretty mediocre old hardware, circa late 2010's Celeron with integrated graphics, getting 20 fps near-field in about the worst case of display, and 40 fps with the far-field heavily LOD reduced.


Aren't other optimizing techniques are out of scope? Why would author implement frustum culling in a tech demo for dynamic LODs?

I'd say if it's proof of concept just to follow the process that Nanite does, then other optimizations are out of scope. However if it's supposed to achieve the same GOAL as Nanite, which I think is provide rich detail at reasonable frame rate then 1) add mode with full LOD to compare performance gains & visual impact 2) do low hanging fruit kind of optimizations as well to match whatever Unreal probably does as well.

Because it's a deeply integrated part of virtualized geometry.

You could just cull an entire object, but the larger the associated geometry, the more unnecessary geometry you keep out of the viewport. This defeats a large selling point of virtualized geometry. It's not just about clustering and simplifying meshes from an extremely high detailed source, but also rendering the portions that are actually important.

That being said, this implementation is very cool as it stands. It addresses arguably the most important actual parts of virtualized geometry, I think.


At least part is probably due to the main news stories that were happening on 1/24/2025. That was the day that ICE started their "Nationwide Deportation Operation" on immigrants and it was the same day that a judge blocked the order for ending "Birthright Citizenship." Here's the summaries from Democracy Now and NYTimes.

Whether it was the SEO folks changing stories to jump to the top of results based on the news, or whether it was the administration trying to get PR support for the activity, it was likely a response.

At least from a personal perspective, there's a chance that it's not especially "nefarious" on the part of the administration, and that it's mostly SEO folks just changing content to try to manipulate search results and jump themselves back into relevance.


SEO folks working for whom?

Hadn't heard of it either until up-thread so I looked. The two primary articles that were found on a search were from Reuters and the San Antonio Express News. Most other seem to just be referencing the Reuters article and using the same quotes. Tend to think the opinion up-thread is probably close, and SpaceX is basically not paying because they can, because people want the work, and because they can make more holding the money and delaying as long as possible, while eating relatively small fees.

SAEN, Feb, 2025: "Contractors say they're owed more than $5.5 million" https://www.expressnews.com/business/article/spacex-unpaid-c...

There's also a "somewhat" unique one from MySanAntonio that goes over the general range of lawsuits that are being filed against Musk in Texas over a range of issues. It happens to include the Reuters article lawsuits and liens as one of the many listed.

Checks out:

Store: Rochester NY and Buffalo NY -> 365 by Whole Foods Market, Large Brown Grade A Eggs, 12 Count, 24 oz, $4.19

Notably, if I put in Downtown LA as the store location, I actually get even cheaper eggs offered. Not sure where this market's getting their prices from:

Store: Downtown Los Angeles, 788 S Grand Ave, Los Angeles, CA -> 365 by Whole Foods Market, Grade A Eggs Cage-Free Plus Large Brown (12 Count), 24 oz, $3.79

It's apparently an API, although it's both difficult to find, and apparently only available through an email request to Albertsons. The website is here:

https://www.albertsonscompanies.com/amc/

The email request is at the bottom. mediacollective at albertsons


I was actually just looking at the calls the web site makes to a back end and using that.

This really been the day of people having great comparisons for companies.

> Is Google dying or dead in this sense now too? I can't think of any company they've bullied recently ...

Such a great summary for judging corporate America.

The European research budget is not insignificant. Horizon Europe 2021-2027 is the current vehicle that much of the funding is going through (European Research Council [ERC] being one of the most well known parts). It has a budget for the time-frame (all years) of EUR 96,899,000,000. [1] Of that, the ERC has EUR 16B [2], Digital, Industry and Space has ~EUR 15B, Climate, Energy and Mobility has ~EUR 15B, and several other sub-groups have smaller amounts.

Those then work with the country level organizations of Science Europe, and those together each spend about EUR 25B each year. [3] It's not insignificant. I tend to pay attention to space, and lately almost all there's been is European achievements in telescopes and astronomy.

Thanks for the numbers!

For comparison, the NSF budget is about $8 billion. DOE Office of Science is about the same. NIH is $45 billion

(Also, compare that with the profit of large tech companies)


That isn’t going to be anything even close to accurate before the week is over and that is kind of the entire point here.

If the sentiment upthread holds, and large numbers of US academics move overseas, then relatively shortly, Europe may shift towards being more willing to make big research bets.

The population shift introduces new ideas, new perspectives, new ways of operating research, new connections towards funding and money, new views on what big bets even means.

The influx of foreign scientists and academics into America over the last century caused significant shifts in how America operated and viewed the idea of research and academia. Post-war Europeans (Von Braun's crowd being an obvious example) caused a large shift in the way America funded "big bet" projects. Saturn V perhaps. Same may happen in Europe.

Those academics can use HN from the opposite side of the Atlantic. VC money especially has the possibility of being territorially bound, yet its often far less constrained by the those types of lines in the dirt than many funding opportunities.


This theory presumes there is shortage of talented researchers in other countries, which is not the case.

There aren't countries with unfilled academic positions awaiting people from the US. If anything, the landscape is even more competitive outside the US.


The sentiments that you see online are meaningless. Ignore what people say and look at what they actually do. I guarantee you that very few US academics will move to Europe. The US has long had positive net migration from Europe, and some temporary changes to federal government funding policies won't significantly change that trend.
