With double-buffering and sync to vblank, your frame rate is an integer divisor of the display frame rate. If your screen displays 60fps but your device can only render 59fps, then you'll actually see 30fps and the device will be idling nearly half the time waiting for vblank so it can switch to the other buffer.
With triple-buffering, if you can render 59fps you can display 59fps. The downside is that it can cause a small increase in latency. It also has On-Live capability, but I couldn't care less about that. Why in the fuck is the Q so expensive? No way that thing will sell against Roku, AppleTV, the consoles this gen and next etc. But none of the features of the Google first-party apps that are bundled with branded Android as opposed to the Android Open Source Project , which is what most of the features highlighted in the keynote were.
I dunno. I'm a fan of the Kindle Fire, and perhaps Amazon can add the hardware features in that month I say that because I'd be surprised if they don't already have designs like that in prototype already , but they'd have issues upgrading their version of Android to be on par with Jellybean in that space of time.
Still, I hope they do. I think the KF was the best thing to happen to the tablet form factor. It was and still is the right price and right size. It focused on a specific use case, and does an. Every time I see that name I think of the Palm Tungsten I don't think anyone has done anything meaninful with Yttrium lately. Watching TV and listening to music are completely different activities. They don't even use the same chair. And the best speakers are for movies, while music is listened to on the car speakers or on headphones while working out and at work.
That said, when reading a book while sitting in the most comfortable chair, which is, of course, facing the TV, you might as well use those speakers to listen to music. People have different use cases. I'm ok with the fact that you don't hook up your awesome speakers to your TV, but there are quite a few of us who do, and apparently we are the target audience.
Yes I, and some others, do travel to places without cloud access. OK: I want to buy hours of video to keep my kids quiet on a road trip. Portable DVD players are also far worse for this.
You have to carry the DVDs, the kids will scratch them. You really can't take them out of the car, they don't offer games, on and on. A lot of Android devices do that these days, and it effectively lets you use any USB stick as external storage - just perfect for those hours of video and such. But, according to this video, flash drives don't just work out of the box. He speculates that you could root your device and get it to work or that perhaps an update will enable it.
BMX Bandit did his part! The bikers zoomed along the roof, doing flips, all streamed live. They rappelled down the side of the building to get onto the appropriate floor, then biked right up to the stage. I see huge barriers towards the mass adoption of a device like that, but you have to apreciate them having the balls to pull off that stunt, genuinely glad I got to see it live.
I'm genuinely curious - is there any independent video from outside the building? Something that shows the whole thing was indeed shot live, and happened as described e. It didn't really feel like a prerecorded video, Sergey Brin looked genuinely unnerved at times and kept reminding the audience that there was a good chance stuff could go wrong, and the way he fist pumped at the end you could tell he was genuinely relieved everything worked out.
I guess you have not tried a high end Android device. The GUI doesn't lag, it is fast and responsive. Occasionally on medium or low end devices there will be a little bit of stutter in the animation due to other tasks needing CPU time and triple buffering will help with that.
I have tried high end Android devices, I got a transformer tablet last year for example, which I ended up swapping for an iPad as it was not quite there yet. Anything using Gingerbread and below is laggy by default because there is not hardware acceleration for the UI. If you've never used an iPhone or a WebOS device you might not be aware of it, but Android, even on the highest end devices can be laggy as hell, in particular whenever the garbage collector kicks in.
When they introduced hardware acceleration in Honeycomb for tablets and then ICS for the rest of devices things improved a bit but it was not what you could call "buttery smooth", it was better by miles but still not that great compared to the experience you get in iOS for example, which is quite frankly, flawless. And this isn't me being an Apple apologist, if you go through my previous posts you'll see I'm a massive Android fanboy.
If you watch the keynote you'll see a demonstration on a Galaxy Nexus. Android has had hardware graphics acceleration from the start, and most certainly did have it in Gingerbread:.
On my Galaxy S if I turn all the animations on they seem pretty smooth, It runs 2. That i. I find it amusing that the Nexus Q you know, the incomplete device that requires hookup to another device to be of any value costs more than the Nexus 7 you know, the complete device that doesn't require anything else.
Methinks one of these devices is going to do quite well in the market and the other will do less well Market it to all the people bitching about how we now buy everything from China and have no manufacturing jobs left in the U. Yes, 3 frames of latency will the be the doom of all user experience.
Why, the latency will sky rocket from. Oh the humanity! If triple-buffered means by extension what double-buffered means in computer graphics, the additional latency will be the time to blit the extra frame from memory to the frame buffer. Way less than. Let's hope the audience didn't really swoon. It's a bit like writing jokes Well, it is a demo and therefore something well past "suspect," but of course the claim is utter smoothness, and depending on just how rigged the demo is, they at least have the visual aids to support that You obviously have no idea what triple buffering is.
There is no extra latency when triple-buffering is used. In double buffering, one renders to the back buffer while the hardware is displaying the front buffer.
When the rendering is done, a buffer swap takes place. However, this does not take place immediately because you will need to wait for the hardware to finish reading the front buffer before it can be made available to be rendered on. Triple buffering solves this wait by providing a 3rd buffer which can be rendered on while the hardware is displaying the front buffer and the previous frame is in the queue. Now, if your rendering is fast enough and you finish rendering while the hardware is still displaying the front buffer and the queued buffer has not been displayed yet, then the queued buffer will be removed and made available for the next frame.
No latency issues here. Triple buffering is required to drop frames if you render faster than they are being displayed. It's the only way to guarantee that there will be a ready buffer to render to. Umm, you don't know what triple-buffering is. It reduces latency by eliminating a bottleneck that exists in double-buffering.
Without double-buffering, drawing is done in the same buffer that is used to refresh the display. This has all sorts of nasty effects when you're changing the display contents rapidly. With double-buffering, drawing is done on a background buffer. When the frame is done, it's swapped with the display buffer and drawing can resume.
The problem is that there is often a period of time when the drawing buffer is completed, but the display buffer is still being used to update the screen, so you can't swap. This leaves the GPU idle, and can cause update latency. Triple-buffering adds a second background buffer. Drawing is done on one of the two background buffers, and when it's done it's queued up to be swapped with the display buffer as soon as possible.
Meanwhile, the GPU can continue drawing onto the other background buffer. In the event that it is completed before the first background buffer is swapped to the display, the first buffer can simply be discarded. More commonly, of course, the first back buffer is swapped in while the GPU is working on the second back buffer. The effect of triple-buffering is to reduce latency, increase framerate and improve smoothness.
More importantly, it allows display, GPU and CPU to all run full speed without any bottlenecks, reducing the chance that a delay in any one of them causes everything to back up.
The first Jellybean device, the Nexus 7 tablet, is shipping mid-July. Also, there are indications that the already-available Galaxy Nexus will be getting Jellybean directly.
The more significant argument for developing on iOS is that Apple users spend more money on apps. Regarding the comments about Android's painfully slow or nonexistent upgrade schedule for existing devices, Google is obviously trying to address this problem by making it easier for hardware manufacturers to port new Android versions for their platform using the new PDK.
However, I suspect that the Android hardware manufacturers are torn about upgrading. Their current model except for the Nexus series is that people have to buy a new device in order to get a new Android version. As a consumer, it sucks. As a manufacturer, it's a dangerous, game, as it tempts people to abandon Android for Apple, where new OS versions are rolled out pretty much across all the hardware. True, but that isn't much help if the market is already flooded with similar apps or if Apple devices to ban what you are trying to do for some arbitrary reason "duplicated functionality" is a particular favourite.
Regarding the comments about Android's painfully slow or nonexistent upgrade schedule for existing devices. There is no such thing as "Androids upgrade schedule", it depends on the manufacturer. Google devices are always up to date. Samsung seem to be pretty good now. If you care about that kind of thing get a device from a manufacturer that is good with updates. In fact since only Apple can supply iO. Ignore the parent, I read a liveblog thing that said the Nexus 7 was out today, but play.
No, its available to order now in the Google Play store, with units shipping in mid-July. See, to pick one of many sources, here [cnet. It's the Q that's shipping in July together with the Jellybean updates for existing Google supported devices. That's kind of a lie. IOS has some features that are only availible with some phones. Ie Siri on 4s only. The problem is only going to get worse with IOS 6.
