3D Gaming*

GT5 supports 3D? Does it have a "real" 3D implementation...in the sense of 2 images computed seperately?

Yes. The game is running at (max) 1280x1080 at 60fps per second with 2xAA or 1280x720 at 60fps with 4xAA, so they could do a 1280x720 at 30fps per eye relatively easily, the way I understand it.

-it has worse ghosting than active shutter, because of the silverscreen, no screen is perfect, it depolarizes light to a degree, this in turn gives worse dynamic range than what the active shutterglasses achieve easily and painless.

BTW, ghosting is more of a problem of PC gaming, because you don't have locked stereo parameters there, but dial in just about any depth/pop out.

DOCOMO has announced the Sharp LYNX 3D SH-03C, a smartphone with Android 2.1 and a 3D touchscreen, among its new models for winter 2010 and spring 2011.

This model has a 3.8-inch 3D LCD with a vertically zoned parallax barrier, enabling naked-eye 3D viewing.

"The LYNX 3D comes with photo, video, and game applications, including a Hatsune Miku promotional video. So you can enjoy a variety of apps and content as soon as you purchase the LYNX 3D. In addition, you can convert your own photos to 3D, and watch mobile TV in 3D as well."

The LYNX 3D converts 2D pictures to 3D by software processing. It can switch between 2D and 3D display with one touch. From now on, 3D content for the LYNX 3D will also be available from DOCOMO Market, which provides application downloads for smartphones.

Passive 3DTV may appear in hotels and hospitals:

3D sets with passive technology could be hitting a hotel room near you.

If you're staying at a hotel with an HDTV, chances are you'll be watching an LG. They're the number one provider to both the lodging industry and the hospitality industry, which means you're likely to find them at hospitals too.

The company has just unveiled two new product lines designed specifically for these industries, but it's the LD950C that's particularly interesting. It's a 3D set, designed for placement in hotel lobbies, restaurants and sports lounges. It's 47 inches diagonally and uses passive 3D tech, so there's no need for expensive active shutter glasses.

… and now for something completely different !

Whoa. While you can't actually buy this i3DG peripheral for your iPhone yet, I'm already imagining playing 3D games created especially for it. You can kiss the 3DS buh-bye.

It figures it's Japan-originated, where creator Jitsuro Mase collaborated with Directions, Inc for an Austrian expo. I desperately hope Mase manages to put it into production, because it looks far better than any other form of "3D" I've seen on something that small, including Sharp's parallax barrier panels that are used in Nintendo's 3DS.

It's quite neat. Need to try it myself to see if it works well under different lighting condition. I wouldn't mind this + PSP2's under-belly track pad.

Sarcasm I hope.

 

[patsu]

Yap, this form of 3D is very limited although the effect is cute.

I do want to see the Sharp screen though. Have heard conflicting opinion about it so far. The show goers in TGS seem to love it though. So I'm hopeful.

Sony is assembling an arsenal of over fifty 3D games in its new assault on the home console market – with over twenty of those titles being built internally.

“We’re actively talking to developers and publishers, and we’re also offering training to them to help them get up to speed with 3D,” he said.

“3D isn’t just about adding depth to a picture – developers need to know how to get the very best out of the technology on PS3 and we’ll ensure that they do.”

Sony’s consultation with external and internal studios, said Hocking, goes beyond training on adding depth. He said there’s also scope to train developers on being playful with the tech.

“Not only make it technically correct,” he said, “but also to be more inventive with it, how to get the most creatively from it for their particular type of game.

“One great example is in Killzone 3, when you're playing in 3D, where the player has to plant an explosive charge on the wall.

“When they do, the charge comes out of the screen and looks like it’s in the room with you, and honestly it feels like an explosive charge has been placed on your TV. It’s
amazing!”

Sony says 3D adds 2% on time and budget:
http://www.develop-online.net/news/36440/3D-adds-just-2-on-time-and-budget-Sony

In fact, SCEE’s Mick Hocking told Develop that converting games to 3D – if the right techniques are used – can add little more than two per cent on costs and time.

...

“So it still works out as quite cheap. The likes of Killzone 3 and Motorstorm are pushing the system as hard as they can go and both of them were converted within a matter of weeks.

“It obviously depends on your particular game and the method that you choose for conversion but done right, great 3D can be added for a very low investment.”

On the issue of how much processing power will be guzzled by stereoscopic 3D technology, Hocking said the results were varied and have yet to show a trend.

“It all depends how a game is converted, if a technique like reprojection is used then is can be as low as 3ms of GPU time,” he said.

“But it all depends how a game converts to 3D. If a game draws two entire frames with split-screen then its developers will find it easier to convert. There are also a lot of new techniques that can drive processor usage down.

“We’ve seen the whole range, really,” he added.

“Games that have implemented it with little impact at all, and more complex games like Motorstorm which is 720p at 30hz and pushes the PS3 to its limits, which was converted in a few weeks.”

...

I think it means they sacrifice resolution or 3D quality.

 

[Billy Idol]

briefly tested 3D mode in GT5

there was an option to setup "parallax" and "convergence" or something like this...what the!
what are those options? can someone please tell me what I can setup with them?

 

[ShadowRunner]

I believe parallax is the seperation of the two images, increase it for more depth but you may find it hard to dial your eyes in on the effect if it is too high. Convergence allows you to control the focal point i believe, in a racing game i guess you would want it set so the focal point is a little way down the track ahead of you, where your eyes will naturally want to focus, but not so far that the seperation on objects in the foreground is so large that you struggle to focus on them. Id imagine the default convergence setting is fine, just increase the parallax until u find the best fit between comfort and effect. People handle 3d differently, my eyes have no problem with absolutely huge seperation but some would find it impossible to focus or get headaches and eye fatigue at the same settings. Also depending on the tv crosstalk may be an issue, in this case even if your eyes are fine with ramping up the seperation the crosstalk may make it look plain fugly. If your TV is LCD your probably going to suffer major crosstalk, if its a decent plasma you probably will have very little, and if its DLP you shouldnt have any at all i think.

thank you for the explanation sir!
I will test to increase parallax...

 

[Gitaroo]

quick question, does 3D mode in GT5 turn off PCM audio like the PS3 does with 3d bluray?

 

[tabs]

@Billy Idol
When setting convergence, you will generally want the closest objects at about screen depth. It's easy to see this if you take the glasses off. The rear bumper will appear to be one image, rather than two, for example. In some racing games the camera angle is such that you can have the bumper 'hanging out of the screen', but typcally this makes the road come out too and it looks a bit odd because it crosses the screen edge.

thanks a lot for the info!
I will test it out!!
but I think the settings Quaz posted fit very well...

 

[jlippo]

Is there any reason why the games haven't got the fov/parallax/converge calculator within them?
I would really love proper 3D with the monitor acting as a window to the game world and not some silly 'human > hammerhead shark' converter.

It would require screen size, distance of player to the screen for it to work, but the effect would be very convincing.
Especially with proper webcamera tracking of eye locations to fix normal problems of head movement and rotations in stereo 3D.
I would be more than willing to keep silly led hat and play right next to the tv to get this immension.

This might be incredible for screen savers as well, Imagine a scenery within the TV which would just be there when you walk by your tv.
Your favorite GT5 car on 'your' driveway just outdoor of your aparment with autumn leaves falling from the trees, perhaps time of day rotating correctly with the clock..
I really wouldn't mind this at all.

At how many frames per second, runs the GT5 in 3D mode?

 

[Quaz51]

At how many frames per second, runs the GT5 in 3D mode?

around 60% of 2D mode

 

[Clerigo]

around 60% of 2D mode

Thanks for the info :smile:

Italy is the First to Broadcast Backwards Compatible 3D:
http://www.highdefdigest.com/news/s...rst_to_Broadcast_Backwards_Compatible_3D/5919

Italian viewers will be able to enjoy the free over-the-air content in 2D or 3D.

…

there's a distinct possibility that owners of 2D televisions will miss out on content created only in 3D. A new format created by a partnership of both private and public parties in Italy aims to solve that.
Rather than side-by-side or top-and-bottom, the group used a new format they're calling 3D Tile. It integrates a pair of 720p frames into a single 1080p frame, which allows reconstructed images to maintain their original resolution. More importantly, it lets viewers with traditional 2D televisions watch 3D content.
