This article is completely, utterly wrong as soon as it starts talking about anything plenoptic. Please disregard after that point as there are serious factual errors, particularly regarding what Google did or didn't do with Lytro. (So

Sadly not; the lens in the eye is somewhat adaptive, but the 'blooming' effect of bright, short-wavelength lights at night mean your eye is incapable of focusing all of the rays onto a single small spot. Unless, that is, the brigh

This is due to dispersion, or ACA (axial chromatic aberration): your eye actually focuses at different depths for different colors. This will be most noticeable for large apertures (so at night, when your pupils are dilated), and for extrem

You're comparing VR to being in the car. The correct comparison is VR to a 2D screen, which is what this is replacing/augmenting. It doesn't need to be the Holodeck to be useful.

The problem is focal conjugates; you can't darken something close to the eye and have it look like a dark region at a distance without focus blurring ruining the effect.

Pettis writes extensively about China and its internal debt problem. The best primer, though lengthy, is to slog through his posts dating back to the mid-2000s. Briefly, though: China has had artificially cheap credit in its corporate secto

With all due respect, interpolating light fields is far less trivial than you make it out to be. It's a 4D field, and naive interpolation leads to loss of detail, and often edge doubling (itself a form of aliasing). Furthermore, if you

If you can drive the underlying display, you can drive the Looking Glass. The pixels you're lighting up just get distributed across views.

The videos are pretty accurate to the experience, having seen them in person a couple times. I don't think there's any cinematic trickery going on.

That's an awfully crude test, that derives its power from its appeal to emotion. Which is not to say it's prima facie wrong, but to point out that its correctness should be separated from its emotional impact, which is very tough

That assumes your pixel distribution has much higher potential addressable resolution than the signal you care about... in which case, why not just display the full raster? Rendering for 2D and display are two different beasts -- but I&#x27

If you don't display the full raster, you're aliasing the signal and will see a lot of view-dependent artifacts (twinkling). Source: I work in light fields.

I skimmed the repo. Setting aside its (probably repugnant, charitably just juvenile) politics, it is objectively not funny. Like, seriously. I'm annoyed I spent 30s scrolling through it. And it reinforces my belief that conservative th

I used to dismiss those obvious Hollywood cliches, but the more I looked into the space professionally, the less silly it sounds. Images-as-data are far richer than images-as-images, it turns out, and clever algorithms can extract a lot mor

This is traditionally called a histogram in video. It allows you to see brightness by region, though it's typically stacked vertically.

Personally, I doubt it barring exceptional circumstance: previous achievement in another field, metrics that can't be ignored (tough to get via bootstrapping, though)... I have heard from some seed stage investors that they will do pri

Hi Justin, Thanks for the article, and putting on a workshop on fundraising. Regarding the workshop -- it seems like the application's only substantial question is "what business metrics do you have to support your beliefs?"

I don't think your analysis is sophisticated enough to capture the actual underlying dynamics. Rating of debt is largely a question of future ability to repay. The concerns of the rating agency, I imagine, is that much of the debt in C

This explains why there aren't external forces that can check the growth in credit. But there has been an explosion in debt within China, financing ultimately non-productive investment. Even with a positive external debt outlook, you c

Excellent, as an American I wish them all the luck in setting up an alternative currency standard. The US has been hurt by the 'exorbitant privilege' of having its currency be an international reserve standard. Dollars that pile u

For a lot of these transactions, the mortgage isn't for the full price of the home. Partially because buyers have other assets (like stock, or cash that needs to be parked somewhere). But also because the mortgage interest deduction to

For all the comments about listing shenanigans, we're overlooking a basic game theory issue here: when you set a price that looks to be near the value of the home, you're saying you're willing to accept reasonable offers. You

I assume that's last "spring," and not that your team is doing agile real estate sprints. But I'd be happy, and rather curious, to be wrong....

Not on a 13k square foot lot! But yeah, that has happened elsewhere in the Bay Area. (Zoning tends to prevent it, though, so there's an element of regulatory arbitrage.)

I doubt that's the "usual" case -- yes, cash-only transactions occur, and foreign investment buyers are in the market, but I don't see a ton of vacant homes. I recall hearing from a real estate agent that foreign purchas

Don't forget Daqri: https://daqri.com/ Enterprise is the one vertical that's still pretty strong in VR/AR, perhaps because sky-high unit costs and dev investment can be amortized more easily.

Open source doesn't mean royalty free (though I have no idea if this format would be royalty-bearing). There are open source implementations of various MPEG and JPEG codecs, but they still carry a licensing fee to use them. Most people
