Transcript of History Of 3-D

What Is 3-D To Us? Everybody knows what 3-D is: images that pop out at you when you wear some type of headgear, but do any of you know how the technology slowly developed over time to give us what we see today?
In this presentation, I will show you the ups and downs of 3-D. (cinema and gaming) Stereoscopy (better known as 3-D) is a technique for creating the illusion of depth when your eyes, aided with some form of eyewear, are used together to view an image from two different perspectives. The two perspectives are created by a regular motion picture camera by filming from two points of view. These images are then placed closely to each other so they just overlap. Most stereoscopic methods present the two images separately to the left and right eye of the viewer. Because our eyes see different images, once our brain processes the images, they are combined to give the perception of 3D depth. What 3-D Actually Is How It All Began The stereoscope was first invented by Sir Charles Wheatstone in 1838. When pictures were viewed with the stereoscope, it showed that the two images were combined by the brain to produce 3D depth. The stereoscope was improved by Louis Jules Duboscq who made stereoscopes and stereoscopic daguerreotypes,which were plates used with the stereoscope to view the 3-D image. (Just like a DVD player needs a DVD to play) Almost overnight a 3D industry developed and 250,000 stereoscopes were produced. Different Forms of 3-D As everybody knows that there are different forms of 3-D available to us e.g. Anaglyph, Glasses-Free and those random plastic glasses used in the cinema. In the next few slides, I will show you how they work and previous attempts of 3D. In 1982, an arcade machine called SubRoc-3D was released by Sega.
The game itself wasn't 3D, but the special cabinet that housed the game gave it a 3D effect.
To play SubRoc-3D you had to look through a special eye-piece that featured a spinning disk that would alternate slightly offset left and right images to give the impression of a 3D depth of field. Subroc-3D LCD Shutter Glasses 3D LCD shutter glasses for the Sega Master System. Each lens of the glasses contains liquid crystals that darken when a charge is passed through it. These flicker in time with the refresh rate of the screen to show a slightly different perspective out of each eye, giving the impression of depth.
Nintendo also released a pair of LCD shutter glasses for the NES at around the same time. Games such as Zaxxon 3D, Worldrunner 3D, Outrun 3D and Rad Racer made the 3D glasses for both manufacturers quite popular, but because of the cost, noticeable flickering, the fact that all games looked like you were playing them wearing sunglasses and limited catalogue of games - eight for the Mega Drive and seven for the Nintendo's console - saw both sets of glasses being discontinued in 1989. Anaglyph 3D

Anaglyph 3D uses two slightly offset images tinted chromatically
opposite colours - usually red and blue. While the 3D effect of Anaglyph
isn't as effective as shutter glasses, it's far more cheaper as it doesn't
require special technology to make it work, meaning that game developers still use it today, with games such as
Assassin's Creed: Brotherhood, Minecraft and Skate 2 featuring anaglyph
modes. Virtual Boy The Virtual Boy was released and discontinued in 1995. Although the system was considered a failure, because of the uncomfortable, neck straining way you had to look at the screen, and the headache inducing red graphics it's an important piece of technology due to the fact that it was the first console built solely around the concept of 3D. Cinema 3D The 3D Cinema Glasses are basically the same as the LCD shutter glasses but instead using flickering lenses, it uses polarised lenses.These lenses block out the wavelengths of light so each eye sees a different image and you know the rest.In recent years, Sony and the PS3 have started championing the cause of 3D, with many well-known titles, such as Motorstorm: Apocalypse, Gran Turismo 5 and Call of Duty: Black Ops featuring 3D modes. Modern 3D gaming uses the same technology as 3D films. Glasses-Free 3D This sounds like a cool idea but it probably won't happen unless you want to get burnt with lava in Mario or fired at with an AK-47 in Call Of Duty. 4D Film and Gaming? Just like all 3D the Glasses-Free 3D make your eyes see two different perspectives. (again) Half the pixels angle slightly to the left, the other half slightly to the right. When you stand a certain distance from the screen they angle into your right eye only or your left eye only. This type of 3D does not require any sort of eyewear so that is why they call it Glasses-Free 3D...(Not that you don't know that. 4D Gaming and Film? This sounds like a cool idea but it probably
isn't going to happen unless you want to get burnt
with lava in Mario and fired at with an AK-47 in Call
of Duty. Thanks For Watching! XD
