Using Tegra 3 Devices for Stereo 3D Output on External 3D Displays

March 10th, 2012 · 4 Comments · Other S3D Tech

Lately Nvidia has been talking a lot about their new Tegra 3 platform and during MWC 2012 together with their partners they were demonstrating a lot of new products based on it that should soon be coming on the market. Meanwhile the only Tegra 3-based tablet that is already on the market – Asus Transformer Prime is getting a lot of attention, but one of the features of the latest Tegra platform, also supported on the Transformer Prime, is kind of overlooked. While there is still no Tegra-based tablet or smartphone with a built-in stereoscopic 3D display, you are able to actually use these devices with a 3D-capable monitor or a 3D HDTV in 3D mode. The Tegra 3 platform officially supports stereoscopic 3D output over the HDMI 1.4 interface, so if you connect it to an external 3D-capable display you can actually use a device such as the Transformer Prime to play 3D videos, watch 3D photos and of course play games in stereoscopic 3D format…

Actually the most interesting part is that the Tegra 3 uses a very similar technology like 3D Vision on PC to enable the stereoscopic 3D rendering of some games. Thanks to the increased performance of the Tegra 3 you are able to automatically, and in real-time, convert some OpenGL based games and apps into stereo 3D and play them on a big 3D-capable display. And the nice thing is that you also have an easy access to controlling the level of depth on a Tegra 3-based device similar to the way that the depth slider works on the 3D Vision.

Here is what you need to do to activate the 3D mode on a Tegra 3-based device:

– Connect your Tegra 3 mobile device to a 3D-capable monitor to 3D HDTV with HDMI 1.4 support.
– Look for Tegra Zone games that support the “3D Stereoscopic” feature, you can easily spot them on the Tegra Zone app or at Tegra Zone web site, use the “3D Stereoscopic” category filter.
– Start the game, the game will automatically be rendered in stereoscopic 3D mode on the 3D-capable external display as the screen of the Asus Transformer Prime or another new compatible tablet or smartphone based on Tegra 3.
– To adjust the 3D depth in game, pull up the quick settings menu (from the lower right corner of screen) and adjust the 3D depth slider left/right to decrease or increase the level of depth you are getting.

Currently there are 16 game titles optimized for Tegra that are supporting the real-time stereoscopic 3D conversion if you connect your compatible Tegra 3 device to a 3D-capable display and thanks to the ability to also use a console game controller together with your tablet you can get something that is quite close to a 3D-capable console. And thanks to the hardware accelerated video decoding and playback features one Tegra 3-based tablet could easily become a portable stereo 3D video player that would allow you to play 3D HD video clips on your big screen 3D HDTV for example. The last thing would of course need some work to make things work the way you want them to, but since there are still not a lot of options available for portable HD video players supporting stereo 3D video playback it is definitely something to dig a bit into. So maybe I should consider getting a Tegra 3-based Transformer Prime tablet to play a bit with and test and experiment with its 3D-capabilities. If you already own one of these devices and have tried the stereo 3D capabilities together with an external stereo 3D display feel free to share your feedback below…

Will Stereo 3D Support be the Highlight at the Mobile World Congress

February 8th, 2011 · No Comments · Stereo 3D Events

The Mobile World Congress in Barcelona will be taking place next week and this year mobile stereo 3D support for different device such as smartphones and tablets could be the main or among the main topics. The 2011 Mobile World Congress will be held 14-17 February, in Barcelona, Spain. It is an event that brings all the big names in the mobile devices industry in one place, all displaying their cutting-edge products and technology that will define the mobile future. And we expect stereo 3D support to be one of the key topics for the new generation of more powerful smart devices such as smartphones and tablets, but will it turn out to be like this is not yet sure. Most companies are keeping their plans secret up until the very last moment, but there are already some information on what will be announced with information about some 3D-capable products set to make their appearance.

And when talking about personal mobile devices in regards to stereo 3D support, we can safely assume that these will feature autostereoscopic 3D displays that do not require you to wear a pair of glasses to see the depth effect. Of course this does not mean that some less known company will not try to offer you a phone or a tabled with 3D support that will require you to wear glasses, but that doesn’t seem practical at all. And especially considering the fact that you don’t need to so many views for the autostereoscopic display on a mobile device and due to the smaller size in general the overall price of the display should not be much higher than that of a traditional non-3D-capable screen. Of course in order to be able to show stereoscopic 3D content, including playing games in S3D mode, the processor inside the device should be quite capable and powerful in terms of performance. So there should be a lot of interesting products and technologies to see during the MWC and we are most likely going to see a lot of the products shown there later this year also hitting the market.

One of the interesting announcements to expect is the new LG 3D-capable tablet featuring 8.9-inch, 3D capable multi-touch display, and ability to record 3D video. This device will most likely be called LG Optimus Pad in Europe, but for different regions it may as well have another name, especially if available exclusively for specific operator. LG will most likely also announce the LG Optimus 3D smartphone, that will most likely feature an autostereoscopic 3D display and a 3D camera. Nvidia is expected to officially to announce their Tegra 2 3D solution designed to power the next-gen portable devices such as tablets and super phones (as they call the Tegra powered smartphones) that will offer stereo 3D support to the user. But you can surely expect that other big names among the phone and tablet makers will be showing their new 3D-capable products too, not leaving all the fame and glory to LG and Nvidia…
