List of Helpful Stereoscopic 3D Related Forums You Should Follow

December 20th, 2009 · 1 Comment · Other S3D Tech

stereoscopic-3d-communities


Although still not many forums that are specific for stereoscopic 3D movies, photos or gaming, there are some that you should be aware of and follow if you are interested or even ask for help other fellow members with similar interests or hardware. Of course here I’ll also mention the support forums of the more popular hardware and software providers for stereoscopic 3D solutions that are a must if you have the respective hardware or software. Also I’d be glad if you provide links to other forums that are worth mentioning, but I’ve missed to link to…

Stereo3D Webboard
This is probably the first and still most popular place to discuss everything about stereoscopic 3D, although the forum is not being very active lately, still it is a good place to find useful information and resources related to everything S3D.

Meant to be Seen (MTBS)
One of the more recent places that covers a lot of different stereoscopic 3D technologies and initiatives that you should follow and seek help in. Created by Neil Schneider, the same guy behind the S-3D Gaming Alliance (S3DGA).

Nvidia GeForce 3D Vision
This is the official support forum for Nvidia’s GeForce 3D Vision active shutter glasses that all owners of the product should check often for interesting things. Andrew Fear the product manager of 3D Vision is also present there from time to time, so this is a way to reach the right guy with your questions.

iZ3D Monitor and Driver Forums
If you are an owner of one of the iZ3D stereoscopic 3D monitors or use their multifunctional 3D driver with other stereoscopic 3D setup you should also be aware of their support forum. You can report bugs and seek help there with some of the guys from the company monitoring the forum and providing support.

DDD’s TriDef Support Forum
The official support forum for the users of TriDef software that is lately becoming more and more popular and widely used thanks to the OEM licensing of the software by Acer in their affordable Acer Aspire 5738DG 3D laptop. A good place for user contributed TriDef game profiles for the Ignition software.

And you can of course also check out our 3D Vision Forum as well…

TriDef 3D Media Player for Video Playback and 2D to 3D Conversion

December 16th, 2009 · 10 Comments · Other S3D Tech

tridef-3d-media-player


TriDef 3D Media Player is the multimedia photo and video player that you get with Acer Aspre 3D laptops and some other 3D displays, but you can as well buy the TriDef 3D experience software separately. Besides the movie and photo player you also get the TriDef 3D Ignition software that is intended to be used to play games in Stereoscopic 3D mode, but I’ll talk about the gaming part with TriDef software in another post and now lets get back to the Media Player…

The TriDef 3D Media Player is intended to be used to play back stereoscopic 3D movies and pictures, along with normal 2D images and 2D movies that can be converted in real time to 3D. The player practically supports all popular movie and photo containers and formats, including support for the proprietary formats used by the developers of the player DDD – .TriDefMovie, .TriDefPhoto and .TriDefPOPvert. The good thing is that you just need to have the proper DirectShow splitter filter and codec in order to be able to play the video in the player and possibly convert it from 2D to 3D in real time. However prior to the just released today TriDef 3D Media Player version 6.5.5 I had some issues with playing back some video files in MOV, TS and MP4 file containers although the system had the needed support installed, but the good news is that the new version has this fixed. I was a bit disappointed by the fact that the player does not support side by side stereoscopic 3D video and I also had some trouble with above/below, although these should be working and with field sequential video too.

What is quite interesting in this player is the feature to convert in real time 2D videos into stereoscopic 3D, even DVD Video and HD clips. However you should know that the resulting 3D effect depends on a lot of factors and sometimes it can be better and sometimes it can be worse, but there are some things that you should be aware in order to get better results. Using higher resolution and better quality videos does help a lot to provide better conversion results, also using videos with steadier and not too fast paced action usually results in better depth perception. A usual problem for 2D to 3D conversions are the fast paced trailers that do have a lot of action and switch between too much different scenes very quickly, so you might want to avoid these, but it won’t hurt to try them just in case. 3D CG animation movies are usually Ok when converted in stereoscopic 3D, but working with 2D drawn or cell shaded Anime the effect of depth is not that good, but there are still exceptions.


fraps-video-capture


And since there are not a lot of stereoscopic 3D movies and even trailers available having an Ok feature that allows you to convert 2D to 3D videos, however being far from true stereoscopic 3D shot or rendered content is still nice to have. You can also do something else with the help of additional software like Fraps for instance (the video recording framerate should be set to match the source framerate and don’t forget to record audio!) – I mean that you can capture the real time video conversion into an Interlaced video format and then share it with other people that do not have TriDef compatible hardware/software to do this themselves, but still have some sort of Stereoscopic 3D setup. After grabbing the converted video stream with Fraps you should reconvert it to something smaller in size, but have in mind that you should maintain high quality of the video compression in order not to get something with bad quality 3D. An example of what you can achieve with the automatic 2D to 3D conversion with the media player is available here Avatar HD Movie Trailer in Stereoscopic 3D Format. Some videos can convert better, other can convert worse… the results depend on a lot of factors, but I’ll say again that this is still not as good as a true stereoscopic 3D content, so don’t get your hopes too high.

The player does not offer a lot of options and the conversion to 3D is almost completely automatic, however you still have control on two things that can roughly be considered to be equivalent of depth and convergence level (the two controls in the right). This allows you to tweak a bit the results in order to minimize the ghosting in the final video or to improve a bit the stereoscopic 3D effect, but still the rest is done by predefined algorithms. And no matter how good are these algorithms for conversion they are still not perfect and can do mistakes like adding depth where they are not supposed to for instance, although considering they do not require any serious setting up they still manage to do their job quite well and don’t forget that everything is being done in real time.

Upgrading your Acer Aspire 3D laptop with latest TriDef Software

December 15th, 2009 · 25 Comments · Other S3D Tech

acer-aspire-3d-as-5738dg


If you are an owner of Acer Aspire 3D AS-5738DG laptop you should know that this mobile computer uses DDD’s TriDef software to provide Stereoscopic 3D support for pictures, video and games. The laptop comes preloaded with an OEM version of the TriDef 3D software that is already not very up to date and if you use the built-in update checker you’ll get information that there is no update available for your software. But on the other hand you can download the latest TriDef 3D Software version 4.1.3 (just released today) and install it over the version that came with your laptop. The good news is that the latest software will work on your laptop and you’ll be able to take advantage of the latest features available in TriDef 3D Media Player 6.5.5 and TriDef 3D Ignition 2.4.6.

tridef-control-panel


The only thing that you need to do after updating the TriDef software this way is to select the type of display the Aspire 3D laptop has, because the software will not recognize it automatically and in the OEM version only the needed mode was available. In order to do that you need to run the TriDef 3D Control Panel and select Line Interlaced (1366×768) mode or just Line Interlaced if you are going to use other resolutions than the native one by the laptop. But if you consider doing that you’ll also have to disable the automatic scaling of the image to fill the whole screen when using lower resolutions, otherwise you’ll lose the Stereoscopic 3D usability because of the different size of the stretched pixels.
