History and Future of Three Dimensional Television, 3D Media, and Safety Part 3
This requirement and perpetuation of the forced wearing of eyeglasses paved the way to modern day’s revival of trying to bring 3D to the majority of Americans. Engineering 3D. Projecting true to life three dimensional viewing was a much more difficult task then simply opening our eyes and perceiving lifelike 3D.
The versions of three dimensional viewing with the help of lenses are alanaglyphic 3D (with red and cyan lenses), polarization 3D (with passive lenses), alternate frame sequencing (with active lenses), and independent eye focusing head-mounted display. These technologies cause each eye to overlap the stagnant images.
Computer software and manipulation technology like computer-generated holograms “produces a sensation of depth” and also can “generate light form the objects themselves” (Manoli, 205). Computer imagery is becoming cheaper and more people are learning the coding languages to edit three dimensional video. Creating a viable means for end consumers to shoot and edit 3D would greatly help the desire to own the technology for recording and playback. Computer monitors would also need to be redesigned.
The projection of 3D technology has come in a few main methods. The previously mentioned patent of William Friese-Greene and the stereoscopic approach to 3dTV is the most produced method to date. The main competition is between the ideas of wearing glasses or developing better technology that does not require assisting eye wear. Just about every major three dimensional use in the public eye has come with some sort of passive or active lens requirement.
There is also technology that allows the projection of three dimensional images without glasses. This technology is referred to as auto stereoscopic display. This exciting technology is arguably a more adaptable model because it brings something new to the market that was not available before. It also reduces the need to purchase additional equipment for families and visitors in the form if additional pairs of 3D capable technology. Concerns over this media suggest that it reduces the viewing area to spaces right in front of the screen which also creates viewing issues for the screen.
Flip Video camcorders are going three dimensional and home camcorders now feature 3D capabilities. Mobile DVD players are also able to play back field of depth images These engineering accomplishments are critical to the ultimate sales of big screen three dimensional TVs by forcing consumers to create their own content and thus a vehicle to play their own 3D home movies. This is among the major obstacles of creating the feeling of need for 3DTVs in the home. Online video streaming service Youtube has plans to produce a 3D channel for hosting and streaming.
