Comment Re:ATW FTW (Score 1) 159

Yes, very quickly -- even more quickly than with other approaches, because your eye saccades really fast. (Although you probably don't have to render intermediate frames during the saccade, because IIRC your brain sort of ignores incoming detail during the movement itself.)

The win is that you have to render a much smaller patch of high-resolution detail, which saves computation in some parts of the pipeline. You've still got to do all the intersection, bounding-pyramid, depth-sorting and whatnot for your whole model (I assume -- it's been close to thirty years since I've done much in 3D graphics), but you don't have to crank out as many pixels. To get "retina" resolution, you'd need a foveal patch no more than maybe 500 pixels in diameter, and the rest of the visual field could probably get by with another 500 pixels on a side. That's a lot less painting than the stack of 3840x2160 screens you'd need to fill the whole visual field at that resolution -- probably between one and two orders of magnitude smaller.

As far as the rest of the pipeline, I guess you win because those rapid saccades don't significantly change the viewpoint (head location), so there won't be a lot of changes to object order or occlusion. (Your pupil does shift its position, since the eye's center of rotation is obviously near the center of the eyeball, but any virtual object that close to your eye ought to be blurred anyhow, unless you're playing the final levels of Quest for Nearsightedness.)

Comment OMG, its orbit is ELLIPTICAL? (Score 1) 119

Now, there's a shocker!

Since the summary stated a period for the orbit, we can assume it isn't hyperbolic. A truly circular or parabolic orbit would be news, since exact numbers like that are hard to come by. And if it were a radial (i.e. intersecting) orbit, well, that would be big news.

Maybe they were looking for "highly eccentric"?

Comment Some diseases stand out more than others. (Score 2) 34

There was a bit of news coverage a while back about childhood eye cancers being diagnosed from snapshots taken with on-camera flash. I have no doubt that detailed scans, processed against a very large dataset, could reveal other diseases that doctors currently don't catch early.

I know, I know, OMG GOOGLE BIG BROTHER, but I'd rather save my privacy outrage for proposals that don't offer a chance to substantially reduce human suffering.

Imagine that -- a brand-new and effective treatment for a formerly-intractable disease is kind of expensive, and doesn't offer a one-shot cure. The evil doctors who came up with this diabolical scheme should be stripped of their medical credentials, if not summarily executed.

If you'd rather just stare at your feet and hope really hard that nothing's wrong, that's still free, and nobody's stopping you.

Comment How are we not all on pay-as-you-go by now? (Score 2) 145

I don't know about anybody else, but my data usage fluctuates pretty widely based on unpredictable travel and other circumstances. For my family, Ting (mentioned above) works out well -- I'm sure my son would love to be able to stream all the time over cellular data, but he's bearing up well under the strain of his deprivation. If we have to spend a week or two on the road, we'll bump up into another data bucket, and pay an extra $10 or so at the end of the month. If not, we get the usual low rate we expect. Same for minutes and messages.

I was on Verizon years ago, and clung to a very old plan with very old flip-phones because I knew pay-as-you-go had to be coming soon. It took a bit longer than I expected, but it eventually arrived, and I couldn't have been happier to kiss Verizon goodbye.
