All 3D Glasses Block a Bit of the Light, but How Much Exactly

January 20th, 2010 · 9 Comments · Other S3D Tech


Everyone is talking about their 3D glasses not blocking as much light as the competitors or not stopping any light at all etc., but does anyone know how much light gets actually blocked when you wear a certain type of 3D glasses? I did a little quick and dirty test to check just that by placing a light meter at a distance of 20 inch (about 51 centimeters) away from display in a completely dark room with no other light sources. Then on the display (120Hz ViewSonic VX2268WM) was shown a completely white image (jps) displayed on the whole screen and I’ve taken out measurements of the light reaching to the sensor of the light meter directly and through a few different types of glasses. The light was measured in Lux units as this way I could measure the intensity of light that reaches your eye without any glasses and when wearing a certain type of 3D glasses based on different technologies…

And here are the results:
– 22″ ViewSonic white, no glasses – 47.2 lux
– 3D Vision active shutter glasses – 41.3 lux (shutters constantly open)
– 3D Vision active shutter glasses – 5.9 lux (per eye with switching shutters)
– Passive circular polarized glasses – 32.1 lux (the glasses from Acer Aspire 3D)
– Anaglyph anachrome red-cyan glasses – 21.9 lux (for red), 22.3 lux (for cyan)
– And a with pair of plain black sunglasses – 15.4 lux

And a little update with more:
– Plain paper anaglyph glasses red-cyan – 7.4 lux (red), 21.3 lux (cyan)
– 3D Vision Discover (anaglyp red-cyan) – 6.3 lux (red), 17.8 lux (cyan)
– Pulfrich paper glasses (clear-black) – 3.5 lux (black lens)

As you can see there is a significant difference in terms of the amount of light that reaches the eye of a person when using different kind of glasses for viewing 3D content with 3D Vision getting the least amount of light passing through. This is normal because of the switch on/off cycle of the shutters in these type of glasses, this however dos not mean that the technology is bad or something like that… it means that just like with other tech you need to compensate with more brightness of the image coming from the screen. But with a passive polarized glasses like the ones from the Acer Aspire 3D you can get more light to the eyes of the user and this is quite important as usually the screens of the laptops are offering less brightness than their desktop counterparts. The comparison with the plain sunglasses is also important, so that you can get a general idea on how things look through the different types of 3D glasses by just taking a look over through your sunglasses and taking into consideration the numbers above. Another thing to note is the difference between the light passing through both color filters on a normal pair or paper anaglyph glasses compared to plastic anachrome glasses (the later have better color reproduction).

CES 2010: Video Interview with Richard Laberge from Sensio

January 14th, 2010 · No Comments · Other S3D Tech

Neil Schneider from MTBS3D.com is here with another video interview from CES 2010, with Richard Laberge, Executive Vice-President and Co-Founder of Sensio. Richard explains how Sensio fits into the scheme of all things S3D, talks about their relationship to S-3D gaming, some of the new partnership announcements etc. It is interesting to hear that Sensio is trying to provide solutions for existing infrastructure to be able to handle stereoscopic 3D content, provided that you have 3D capable hardware for visualization of course. Sensio has announced partnership with VIZIO for including Sensio’s decoder in their 3D-capable TV’s expected to hit the market in the second half of 2010. Besides that Sensio is also targeting digital download and cable distribution services for example where there are significant bandwidth limitations and a solution that does not require to replace or upgrade existing distribution infrastructure to provide 3D content is more than welcome. Another interesting thing about Sensio is their partnership with ViewSonic and the upcoming integration of Sensio 3D technologies in some of the ViewSonic’s products. THX and Sensio also announced partnership for THX Media Director technology that is designed to simplify the home entertainment experience by auto-detecting if you are feeding the TV with 2D or 3D content and switching to the respective mode. But lets see how will things develop further, as there seems to be a lot of competition coming in that field this year…

Intreview with NEXT3D at CES 2010 about Their NEXT3DTV Services

January 12th, 2010 · 1 Comment · Other S3D Tech

Neil Schneider from MTBS3D.com did another video interview at CES 2010, this one features David Cole and DJ Roller, Co-Founders of NEXT3D. What is interesting here is that the company plans to launch its Next3DTV service – a broadband-delivered stereoscopic 3D HD video download beginning in the first quarter of 2010, so this means pretty soon and even before Blu-ray 3D titles start to appear. Next3DTV is supposed to offer a variety of stereoscopic 3D content, including theatrical 3D movies, films originally created for 3D IMAX theaters, movie trailers, sports, news, documentaries, live 3D weather maps, and games. Additionally it will offer user-created content channels for stereo 3D enthusiasts to post and share stereoscopic videos and still images. Movies, special events, games and other premium content will be offered on a rental basis (you’ll not own the content), while some of content will be free for everyone. One of the first announced big content providers for Next3DTV is Turner Broadcasting System with others probably soon to follow.

Next3D has Stereoscopic 3D Full high definition encoding and player technology for nearly every platform: PCs, Mac, Xbox 360, PS3, Blu-ray disc and television set top boxes. Content encoded with Next3D’s enabling technology delivers full stereoscopic 3D in 1080P high-definition to the home over a broadband, cable or satellite TV connection. Next3DTV will be initially available for PC’s, with support for Mac, game consoles and select set top boxes to follow. For PC users, Next3DTV will support 3D Laptops, most NetTop PCs, and modern PC’s with NVIDIA or ATI video cards. During CES 2010 the technology has been demonstrated on NVIDIA 3D Vision System. So far in theory everything sound very good, but the gaming part is still not very clear as well as the international availability of the content and of course the pricing, because of the content rental and you not actually purchasing and owning the 3D content. An affordable monthly subscription plan, just like a cable TV, with access to all the content along with good and always fresh stereoscopic 3D content might make things very interesting for everyone.
