3D At Home . . . Really?

The latest development in stereoscopic technology is the 3d television. They are fairly new and haven't become common in homes. There's been a lot of buzz about these new TVs, but there's also been a lot of skepticism. I tend to lean on the side of the skeptic. I'd just feel like an idiot sitting in my living room with a pair of 3d glasses on.

Different Types of Glasses

The most familiar elements of stereoscopic 3D are the glasses issued to the viewing audience. There are different types of glasses used to achieve the same illusion of depth.

Anaglyph glasses use color filters to control the image that each eye sees.


Polarized glasses use a different type of polarizing filter for each eye.


Shutter glasses are relatively new and use battery operated shutters to control what each eye sees These glasses are becoming popular with 3D televisions.
