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, but currently require a very precise viewing angle. Consumer displays and televisions that support 3D technologies began to appear on the markets in 2010.

  • 3D video will represent a new way of teaching (both over the Internet and by face to face) in professions that leaner need to be dexterous, where learner need to be taught skills, techniques and procedures that will be imperative to the delivery of services to their clients.- Olufemi.Olubodun Olufemi.Olubodun Oct 4, 2010
  • 3d video will best be used for displaying situations where the understanding of 3D is required (think chemical structure, nanotech, engineering, art) and outside the viewers current understanding and experience - alanwolf alanwolf Oct 17, 2010.

(2) What themes are missing from the above description that you think are important?

  • - dicksonk dicksonk Oct 15, 2010 No question that 3D when it finally arrives in a scalable form will be powerful. A friend in broadcast television recently remarked that at $1m an episode, current 3D programs will not last long past the current seed money provided by 3D television set manufacturers. I have no verification for the claim, but we have slowed our own investigation of 3D a bit until the current set of claims--often promoted by the same 3D TV companies--can be demonstrated in the field with more broadly accessible equipment.
  • Humans are very good at understanding 3D from 2D representations from our experience and the perspective. 3D may not add much in commonly viewed scenes, and as noted above, the cost differential for both the content creation and viewing tools may reduce the speed of uptake. It should also be noted that some are motion-sensitive with regard to 3D video - alanwolf alanwolf Oct 17, 2010.
