We live in a 3 dimensional world, as we see and hear form, shape and depth all around us.  The universe itself is not limited even to 3 dimensions, but for the average person, it is the substance and depth that distinguishes our surroundings. 

Pictures, movies, television programs and art are displayed in two dimensions.  The difference between 2 dimension and 3 dimension is comparable to the difference between a square and a cube.  Length, width and height are found in both, but the 3^rd dimension adds depth. 

3D is a natural form of human perception.  Our ears can each pick up a different sound or tone and our brain will naturally merge these individual sounds together to create a single, flowing auditory sensation.  This is the very dimension that popularized stereo sound, surround sound and so on. 

Adding a third dimension to the sounds we hear proved relatively uncomplicated, and movies, television and recorded music often sounds as good (if not better) coming through speakers as it would if it were being heard live.  For the most part, 3D sound relies on establishing the right balance of space, frequency and distance that sound travels to reach each ear, so it will combine to sound natural, rather than manufactured. 

Converting visual elements to a 3^rd dimension, however, has proven much more difficult.  The same way each ear picks up pitch and audio components which the brain can smoothly interpret and relay as a single sound, so too are the functions of the eyes.  Each eye picks up a distinct visual signal, which is why you need both of them to see properly.

Turning manufactured images into something with depth has been a challenge for many decades.  Using red and blue plastic glasses on a broken prismatic image was only the first step to bringing the visual arts to life with 3D. 

At long last, science and technology have penetrated the barriers that made 3D images so difficult, and we are finally on the cusp of a revolutionary change in the way we view movies, pictures and videos. 

The 3D technology used to view movies on the large screens in theatres, is making its way to homes around the world.  Using IR transmitters and specialty shutter glasses brings the once flat, 2 dimensional images into the third dimension. 

We are just now seeing this technology trickle out into the consumer marketplace, but make no mistake, just as with cell phones, gps and other advances, once the technology has been consumer tested and tweaked, it will be everywhere.  Life in 3D.  Just as it should be.
