3D (3-Dimensional) technology seems to have arrive to the forefront, thanks to the blockbuster world-wide success of the movie Avatar and other releases in the 3D category. So what is 3D anyway and how does it compare to HD (High-Definition) all
Well, HD (also known as Hi-Def) is video characterize quality with considerably higher record resolution than the old-fashioned Standard-Definition (or SD) . HD generally has about 1 to 2 million pixels per frame which is probably 5 times compared to SD. Therefore, the record quality is very high quality and spirited, you can't compare the quality to SD.
3D on the other hand is another dimension altogether. When watching video in 3D format, the pictures seem to jump outside the cover giving it a real-life-like experience (as if you were experiencing it true there and then) . 3D experience is achieved through a technique called Stereoscopy.
It's based on the method the human brain and eyes work together. An individual's pupils of the see are about 6.5 cm (or 2.5 inches) apart, therefore each peruse views a scene from a different angle and generates a current image. The brain then merges the images to perform a single record. The shrimp incompatibility between the image from the accurate seek and the image from the left perceive allows the brain to deem the depth.

There are mainly three types of 3D technology and each one works differently:
The first type, anaglyph technology, is the most noted one (the red/blue paper glasses) but usually the 3D effects are not all that tremendous. This type of technology has been old numerous times in cinema theaters, mostly because the red and blue glasses are an inexpensive option.
The second type, polarized technology, is the technology you've experienced when watching 3D movies in an IMAX theater, for example, Avatar 3D, Alice in Wonderland 3D and others. To compose that 3D achieve, two images are projected onto the same cloak through different polarizing filters. The viewer wears low-cost eyeglasses which also occupy a pair of different polarizing filters.
The third type, active technology, is starting to become more mainstream and standard in terms of 3D watching for home exercise. With this technology, an HDTV will indicate one image to your left ogle and one image to your true glance. Active liquid crystal shutter glasses are then passe by the viewer and expeditiously block each glimpse in sequence to ensure that each search for only sees the corresponding image being displayed on the 3D TV status.
