PlayStation 3's 3D implementation explained, may require upscaling and reduction in detail to work
It was only a couple of days ago that Sony flicked the switch on 3D compatibility for the PS3 -- albeit without retail games that can yet exploit it -- so what better time to dig into the nitty gritty details of the company's implementation of the third dimension? Digital Foundry have done just that, starting off with a discussion of how Sony translated WipEout HD from 2D into 3D. Noting that the original version ran at 1080p, Sony's senior development manager Simon Benson explains that notching resolution down to 720p opened up some pixel processing overhead (one 1080p stream requires nearly 2.1 million pixels, whereas a duo of 720p images is around 1.85 million in total), while reducing the refresh rate to 30Hz allowed the devs the breathing room to complete the extra geometric calculations required by 3D. That's certainly not the 1080p video at 100Hz per eye that we were hearing about at IDF last year, but at least it shows that games that haven't been coded for 3D can be translated, albeit at more demure settings. In the case of Motorstorm: Pacific Rift, the game already ran at a 720p / 30fps clip, so the solution was to generate it at a lower resolution and to use hardware upscaling and a few optimizations to make 3D work. Lest you think the transition was all bad news on the graphical immersion front, the SCEE devs also mention that quite a few field-of-view and motion-illustrating effects could simply be disabled in 3D, as in that mode "you get [them] for free." Of course, we're still only talking about retrofitting 3D, and Sony's big hope is that developers will code for the new format right from the start, resulting in visually richer and technically more efficient implementations.

PS3 3D video output turns up in 3.20 debug firmware
We'd already heard that the PS3 wouldn't need anything more than a simple firmware update to make the jump to 3D, and it looks like we now have the first evidence of that very firmware update. It's obviously not ready for public consumption just yet, but a debug build of the 3.20 firmware is apparently now making the rounds among developers, and it quite clearly includes a "3D Video Output" option in the settings -- as evidenced by this image courtesy of VG247. Still no word of an exact release date for the firmware, unfortunately, although it should be out sometime this summer. [Thanks, Richard]
PS3's new 3D mode captured on video, coming in 2010 to all existing games
You know what's absolutely useless? A video of Wipeout HD being played in 3D, with some schmuck wearing 3D glasses and babbling on about how much fun he's having. Well, that schmuck is this Engadget editor, the video can be found after the break, and we've gotta say: we loved it. Especially for something like Wipeout HD, whose neon-infused tracks make for an almost too convenient example of rapidly approaching vanishing points, we'd say 3D could really be a quasi-"killer app" for consoles going forward -- especially if those fancy new motion controllers don't catch on for Microsoft and Sony. In many ways, 3D just seems to make more sense in a video game than for a movie, and the whole problem of finding content to deliver in the format has already been solved: a software update for the PS3 sometime in 2010 will enable it to provide a 3D viewing experience to "all" existing games on the system. We're sure there will be some exceptions, but it sounds very promising. The console itself pumps out a quite regular signal over HDMI, which the TV syncs up with your 3D glasses. A 200Hz TV, for instance, alternates 1080p frames, with 100Hz for each eye. Of course, you'll need a brand new TV, but at least it won't be restricted to just Sony televisions. Start saving those pennies!
