Phoronix: Intel Linux Support For HDMI Stereoscopic 3D

New patches have emerged today for supporting Stereoscopic 3D, as part of the HDMI 1.4a specification, with the open-source Intel Linux graphics driver...

Gallium3D

Maybe Stereoscopic 3D would be something that could be put in Gallium3D?

respect! .

And nvidia?

I always wondered why the hell on windows every card has support for stereo 3d, but on linux you need a quadro.
Yes, something about quad buffered visuals, but i don't think intel cards provide that.

Shame on you nvidia!

[CrystalCowboy]

Great. Is Stereo 3D also going to be supported on DispalyPort 1.2?

So some time has passed and I'm sitting at a hd 3d projector with shutter glasses right now.

First I have tried using windows 7. It was VERY disappointing. There is nearly no hdmi 3d support anywhere. The only thing that did somehow work was tridef 3d with the AMD HD3D HDMI 1.4 output setting. It set the projector to the 3d mode which is needed for it to activate the shutter glasses. Dirt 3 worked well, in Trackmania Nations I had very visible ghosting, but at least it was 3d, for skyrim I had the enb mod installed and this mod does makes tridef3d not work. I have to wonder why the only way for playing most games in 3d is some quite expensive (I wouldn't use it very often anyway) 3rd party software while nvidia has their own solution.

Come on, companies. 3D is in a really sucking state right now with all those different ways... Side by side, side by side half size, top bottom, top bottom half size, checkerboard, line interlaced, column interlaced, native hdmi 3d/frame packing, etc, etc. Why do you want to make it even more error prone by each one doing their own solution? Why?

I also tried to play a 3d video I downloaded from youtube as 3d. I tried several players like bino, arcsoft tmt6, 3dtv.at's "Stereoscopic Player", etc. but none of them does seem to use the hdmi 3d mode. Only the tridef 3d movie player set the 3d mode but it crashed instantly.

I have found references to a nvidia 3d vision player but as I do have an intel chip with a radeon using amd enduro in my notebook I could not try it. But I now understand why nvidia is so successful in pushing their proprietary stereoscopy solution: The competition is somewhere in extremely weak to nonexistent.
Try it yourself: Type "3d video player" in google. I have spent some time there and found almost nothing useful there.

The only thing that works is making the player output the video side by side and then setting the projector/tv to interpret the side by side picture as one 3d picture. That works, but has the obvious drawbacks of having all 2d gui stuff displayed very bad, always having to enable/disable it by hand and only having half the horizontal/vertical resolution on the screen.

So now I am on linux again and I also have found next to nothing how to use this stuff.

There was this article:
http://www.phoronix.com/scan.php?pag...item&px=OTkwMA
So unigine heaven has this now:

But there is no hdmi 1.4 3d. Why?

lastly there's a new "testdisplay" addition to the intel-gpu-tools package for testing the Top Bottom and Frame Packaging modes.

How do I use it? I don't see a man page and the mailing list message doesn't tell me much. I assume at now everything is in upstream linux 3.8 rc and git master. So how do I interpret the output? Is any of those a 3d mode? From what I have read a 3d mode should have twice the width so that two full hd images can be transmitted at the same time. Do I need to add a modeline to randr myself?

[Hi-Angel]

There was this article:
http://www.phoronix.com/scan.php?pag...item&px=OTkwMA
So unigine heaven has this now:

But there is no hdmi 1.4 3d. Why?

I'm just trying to get an info of how it everything works too. As I understood, probably when you're choosing some 3D option in a soft, it should switch your monitor into 3D mode via HDMI. I didn't get yet more information, though.
