The 1080p 3D-capable Projectors and Gaming in Stereo 3D Mode

May 9th, 2011 · 6 Comments · Other S3D Tech

There are a lot of people that expect this year to finally see 1080p 3D-capable projectors on the market with more affordable prices, thinking about upgrading their current 720p 3D projectors or directly going for such a solution with gaming in stereo 3D mode as one of the main things to do on a big screen. Currently one of the most affordable 1080p 3D projector is Sharp XV-Z17000 available for about 3-4K USD, but even this is considered high for more mainstream users not looking to build a home movie theater, but instead planning to use the projector for gaming. Especially considering that there are some mainstream 3D-capable 720p projectors such as the Acer H5360 available for just about $600 USD, so paying 2-3 times that price for a projector supporting 3D and 1080p resolutions sounds reasonable, but more not so much.

Leaving the still higher price for 3D support and 1080p resolution as features available together in a projector, there are some other important things that you should consider if you are looking to buy an 3D Full HD projector for gaming. Having an industry standard such as HDMI 1.4 is good for a lot of things, but can also bring some issues because of some limitations it implies on hardware that is using it. And you can expect pretty much any 3D-capable 1080p projector for consumers that is expected this year to be based on that particular standard. For movie lovers that should not be a problem as the HDMi 1.4 standard supports high enough bandwidth to push 1080p at 24Hz in 3D mode, but for gaming in stereo 3D mode this is simply not enough and you should go back to 720p resolution where you can get 50 or 60Hz per eye in 3D mode. So what is the point in going for a 1080p 3D projector using HDMI 1.4 if you plan to use it for gaming – absolutely no point in doing that. You better stay with a much more affordable 720p model if you have one or go for such 3D projector for playing games in stereo 3D mode, and you can of course play 3D movies in 1080p resolution on it without very significant visual quality “loss”.

In 720p resolution you would have to use some Anti-Aliasing to smooth the jagged edges in games, something like 4xAA should be quite close to what you get at 1080p resolution without AA in terms of edge smoothness, although there would be still some difference in the level of details you get. But in general playing at lower resolution may also help you get by in stereo 3D mode even with not a top-end video card with a decent framerate as compared to playing with the same hardware on 1080p display for example. And having a bigger projected screen helps a lot for the immersion as compared to a much smaller 3D monitor for example that may have higher resolution, not to mention the fact that 3D DLP technology is practically crosstalk/ghosting free in 3D mode.

Having a 3D-capable projector using HDMI 1.4 has the advantage that it should be compatible with much wider range of hardware, not only PC (Nvidia’s 3D Vision and AMD’ HD3D technology), but also standalone consumer electronic devices with support for 3D such as the PlayStation 3 console, or a Blu-ray 3D player. The disadvantage when using HDMI 1.4 is that it only supports 720p 50/60Hz 3D mode and 1080p 24Hz 3D mode, the rest is only in 2D mode and you cannot use the projector at 120Hz in 2D mode like you can do with projectors using HDMI 1.3 or VGA interface for example (this can vary greatly on the specific projector).

So if you are waiting for an affordable 1080p 3D-capable projector to become available in order for you to use it for gaming in stereo 3D mode and not for 3D movies, then you should probably reconsider your decision…

Acer H5360BD is an Affordable 3D Projector with HDMI 1.4a Support

March 24th, 2011 · 14 Comments · Other S3D Tech

If you still haven’t noticed, Acer is among the top companies pushing products supporting 3D technology lately, aside from all the top CE brands such as LG, Panasonic, Samsung, Sony etc. of course. Earlier this month the company has announced the successor of their popular 3D Vision-ready Acer H5360 projector with 720p native resolution – the Acer H5360BD. The main difference between the two is that the new Acer H5360BD 3D DLP projector comes with support for the new HDMI 1.4a interface – an industry wide standard supporting stereo 3D. This is a very good news for everyone looking for an affordable widescreen HD projector that supports 3D, and that can not only be used with 3D content coming from PC, but also from consumer electronic devices such as standalone Blu-ray 3D players or game consoles like the PlayStation 3. The Acer H5360BD projector has a native resolution of 720p (1280×720) and 16:9 aspect ratio, 2500 ANSI Lumens maximum brightness and 3200:1 contrast ratio, together with up to 4000 hours of lamp life.

So far everything sounds great, but there is something very important that you should be aware regarding the new Acer H5360BD and this particular thing is the major difference between this model and the older one, aside from the addition of HDMI 1.4a support. That difference is the fact that the new Acer H5360BD projector is not 3D Vision ready, meaning that you will not be able to officially use the 3D Vision shutter glasses with it like you can with the previous Acer H5360 model. This particular thing is related to the addition of HDMI 1.4a, and as this projector features this interface for stereo 3D data transmission, although you are not able to use it with 3D Vision, you can use it with the 3DTV Play play software. Using 3DTV Play with the projector would still require to you use a pair of DLP Link glasses to actually see the projected stereo 3D image, as again the 3D Vision glasses are not going to be officially compatible with it. So when using the Acer H5360BD projector with your PC as a source of 3D content, along with the 3DTV Play software, you would be pretty much be using it like you would with a 3D HDTV that also requires its own shutter glasses and in the case with 3D DLP projectors you need a pair of glasses supporting DLP Link (no matter what the brand is). And since the projector is 720p, you would be able to get it to run with 60Hz per eye when in 3D mode, something that is supported at that resolution over the HDMI 1.4a interface, so no worries about the framerate for gaming.

The HDMI 1.4a support that the Acer H5360BD supports should also ensure compatibility with AMD’s HD3D technology, at least in theory, no guarantees about that unless this is tested. Nvidia has already confirmed that the projector is already supported in the latest 3DTV Play Update Utility v1.0.0.18, so that is for sure. Have in mind that the Acer H5360BD projector should be starting to be available on the market sometime in April with a price probably slightly higher than the current price of the previous model Acer H5360, positioning it as probably the most affordable 3D projector to feature HDMI 1.4a support on the market.

German Amateur Stereoscopic 3D Short Movie – The Shadow of Justice

February 24th, 2010 · 4 Comments · 3D Movies & Videos

Here is a new German amateur 3D short film called “Der Schatten der Gerechtigkeit” (The Shadow of Justice), probably the first German amateur short film shot in stereoscopic 3D. The movie is in German, but the version below is with embedded English subtitles in 3D, so that you’ll understand the dialogues (other versions are also available). The production was done with a custom side-by-side camera rig using Canon HV30 and HV20 HD cameras, because these cameras were already available, along with the rest of the equipment, so it was basically a no-budget production. For the post production a Zalman 3D Monitor was used and Acer H5360 3D projector for previewing the material in stereoscopic 3D, all the editing was done in Adobe Premiere Pro and the compositing in Adobe After Effects.

The length of the movie is 13:31 minutes and it is available in HD quality (1280×720) in Over/Under format with the left frame first best viewed with 3D Vision Video Player or Stereoscopic Player, but any other 3D setup should do. The movie is also available in anaglyph format, on Youtube 3D and in 2D version, but only the Over/Under version linked below has English subtitles, the rest are all available only in German for the moment. The end result is great, especially considering we are talking about an amateur short movie and not a professional production, but then again it also took over 8 months to prepare everything you’ll see in the video.
