What is 3D Video?

3D video is not an entirely new technology, having been around in the film industry for many decades. However, the technologies that deliver this immersive form of video viewing are improving. New cameras, better viewing glasses, projection systems, software, and displays are starting to bring 3D video into its own at the consumer level, enabling new forms of creative expression and imaging. 3D video requires the capture of two images simultaneously, the same way our eyes do. Once captured, this dual imagery must be displayed or projected in a way our eyes and brain can resolve enough to be believable with the assistance of specialized eyewear. New LED-based systems that do not require special glasses show considerable promise, and consumer displays and televisions with 3D technologies began to appear on the markets in 2010; they have become popularized through more affordable models by companies such as LG and Toshiba. Contemporary applications and software are enabling people of all ages to produce their own 3D videos.

(1) How might this technology be relevant to the educational sector you know best?
  • In time, will allow us to display virtual 3D objects. This will be good for sharing objects that can't be easily displayed for various reasons, or objects we don't own. For instance, maybe it's a recreation of an object that no longer exists. In the near future some of this technology will have a "wow" factor with the public, and in time people will expect that we use 3D video for some content, although not everything. - ortiz ortiz Feb 16, 2016
  • We are looking to add 3D video to enhance audience engagement with our Period Rooms and larger design objects (e.g. http://collections.artsmia.org/art/98653/tatra-t87-four-door-sedan-hans-ledwinka ). Our experiments so far have been minorly-successful. With the near-horizon delivery of improved viewing devices, this holds promise - as written above - for audiences to experience places and things that are inaccessible or off-limits. - dhegley dhegley Feb 26, 2016- jludden jludden Mar 2, 2016

  • Seconding comments above, though I'm feel like the "in time" part of this is important-- could be something with impact, but until the devices are improved, it still feels like something with promise, but not here yet. - jfoley jfoley Feb 29, 2016

(2) What themes are missing from the above description that you think are important?
  • I'm struggling to see the clear distinction between 3D video and VR. If the dividing line is intended to be the difference between video delivered as VR and "renderings" delivered as VR I feel that this is a bit of a false dichotomy. Thoughts? - njohnson njohnson Feb 27, 2016
  • And a clear distinction between stereoscopy (illusion) and geometric modeling (used in VR - which can also be made stereoscopically). Due to a mass media advertising of 3D movies, 3D glasses...there is still a lot of missunderstanding among the users what 3D means. - kaja kaja Feb 27, 2016
  • The difference as I see it is that 3D video is simply a technology for adding 3D to traditional forms of cinema and moviemaking. VR, as it is being proposed (still too early to know how it pans out), would offer a more interactive, less linear environment, even when deployed as a filmmaking platform. Another way to look at this is the 3D video remains a "passive viewer" technology, while VR proposes an "active viewer" platform. We'll see if that happens.- weberj weberj Feb 28, 2016
  • I like the idea of a potential distinction point between active/passive viewing. If 3D video is, indeed constrained in a passive construct then I see a more clear line between it and traditional notions of VR. - njohnson njohnson Feb 29, 2016- jludden jludden Mar 2, 2016

(3) What do you see as the potential impact of this technology on education and interpretation in museums?
  • There will be a great opportunity to present virtual 3D objects or environments, or to show videos that have a certain immersive quality. This can be useful in science and technology museums, but will have applications in other types of museums as well. 3D video's current use in Hollywood is not as applicable to current museum strategies, but in time there will be opportunities to utilize it effectively based on the museum's content. - ortiz ortiz Feb 16, 2016- jludden jludden Mar 2, 2016
