Why not have a separate chat request to apology-check the responses? Not my original idea, there was a link from HN where the dev did just that.

Can anyone who has seen these demos confirm if they are 6 DoF (the perspective changes with viewer position) or merely stereo? The latter is boring and easy to implement, the former much more compelling and technically difficult.

That’s not how parallax works. The wider field of view of the ultra wide camera will show some of the scene that the other camera doesn’t see, but over overlapping parts of the scene the parallax is a strict function of the location of the

The results cited in the article suggest that either the answer is yes, or in fact "marginal students" are perfectly capable students who were being passed over. The text of the article further suggests that many of the students w

Yeah the article is a little muddled; it’s better to understand Anchor as the oldest existing brewery that makes what we think of as craft beer. When it started there were many small, local brewers making a variety of beers. Prohibition and

I read an article in a craft brewing mag (might’ve been “Celebrator” circa 2003) that pointed out how the craft brewers association kept revising upward the number of barrels/year production that still qualified as “craft” so that it c

For the pedantic record, "regulatory capture" typically refers to a situation where an entity responsible for regulating another entity is controlled or influenced by the body it is meant to regulate. Like if the SEC was influence

This is a very good guess, and I believe it's precisely how it's done. Doing anything diff-ing the color channels still requires a lossy transformation step, so it's not quite as "raw." And you're right, that t

I think it had more to do with the requirement that three chip camera lenses be telecentric (see my earlier comment). Tends to make worse lenses that are more expensive.
131.
by ryandamm 4y ago
Yeah, they used telecentric lenses; for the prism block to work properly, you have to have each principal ray across the lens perpendicular to the filter. This puts very rough optical constraints on the lens; a typical video camera lens wou

Yeah this is all accurate... there is a lot of marketing at that company, which is unsurprising given that it was founded by Jim Jannard, who made his money selling consumer fashion goods at Oakley.

But they are collecting royalties from Apple and others...

We actually have had major patent reform! Look into IPR review, the Alice Supreme Court decision, and the patent reform act of ... was it 2012? 2013? The IP landscape is wildly different than it was when these patents were first filed. That

I do find myself wondering what fraction of Red's revenue is IP vs camera sales. No particular reason, just curious -- these patents sound rather profitable.

The F900s that Lucas shot Episode 1 on recorded at sub-1080p resolution, _before_ being letterboxed. That was a long time ago.

Red isn't a consumer company. How are they anti-consumer? I'm not defending their IP practices, but this is not as stupid as it seems. Nikon knew about the patents when they designed their cameras. The patents were not dumb in 200

by ryandamm 4y ago
Well... yeah, that's the crux of it. But the patented part is treating each channel separately; the actual compression algorithm isn't at issue (which, in Red's case, is JPEG2000). That said, as soon as you get into colorspac

Again, the patent to compress Bayer pattern data before de-Bayering is the pivotal one. There's a reason Apple is still paying royalties, and it ain't because they don't have good lawyers.

by ryandamm 4y ago
Keep in mind that video cameras of that era were mostly not bayer pattern sensors, at least for professional television cameras. They were three, full raster sensors, typically with an interference-based prism block shunting blue, green, an

I don't think so -- I think it's a reference to Gollum, the apes in "Planet of the Apes," the de-aged Moss Tarkin (sp?)... basically CG people. That work is almost entirely at the high end, because it takes a lot of digi

I think this is straightforward technical language being translated into patent language. But you should always read the claims; the language is usually more precise there. I believe the technique at issue is a way to compress the data -- u

by ryandamm 4y ago
I haven't pulled the patents, but they probably have to do with compressing the pre-debayered image. Apple sends Red a big check every year for the same patents; I believe they're part of ProRes but not sure. Essentially, by compr

Do you have any background in movie production? There is more to that industry than VFX tech. Yes, virtual production etc are ascendent, and growing fast -- but most of the production spending is still using fancy optics and traditional pro

It’s a combination of surface tension and buoyancy; the resulting minimum energy surface can be designed to whatever freeform shape you want by controlling the liquid density and the geometry of the frame.

Can anyone offer insights to how reliable this article is? I don’t know the field and am reduced to looking at superficial signals, like: I see business school bylines and the “see additional publications by this author” links don’t turn up

In case you're not being facetious: It just means that Color Star's advertisements are no longer visible in the 76ers' arena (because the partnership was terminated).

I'm genuinely not sure whether this statement is pro-crypto or anti-crypto... I assume it's anti- based on the reference to it being better for the planet? Or is the "designed for hyper consumption" a reference to inflat

Centralize it and implement something like M-Pesa, or build it on top of the existing mobile networks. The solution is selling standardized contracts to small hold farmers that pay out automatically; the problem has nothing to do with decen
