Abstract
This is an attempt from our part to present the future of internet which would be in 3D.In the time when 3D televisions and 3D movies are a reality, 3D Internet should be the topic of discussion.

Introduction
In today’s ever-shifting media landscape, it can be a complex task to find effective ways to reach your desired audience. As traditional media such as television continue to lose audience share, one venue in particular stands out for its ability to attract highly motivated audiences and for its
tremendous growth potential — the 3D Internet.

Also known as virtual worlds, the 3D Internet is a powerful new way to reach consumers,
business customers, co-workers, partners, and . students. It combines the immediacy of television, the versatile content of the Web, and the relationship-building strengths of social
networking sites like Face book. Yet unlike the passive experience of television, the 3D Internet
is inherently interactive and engaging. Virtual worlds provide immersive 3D experiences that
replicate (and in some cases exceed) real life.

People who take part in virtual worlds stay online longer with a heightened level of interest.
To take advantage of that interest, diverse businesses and organizations have claimed an early stake in this fast-growing market. They include technology leaders such as IBM, Microsoft, and Cisco, companies such as BMW, Toyota, Circuit City, Coca Cola, and Calvin Klein, and scores of universities, including Harvard, Stanford and Penn State.

Augmented reality
The Augmented Reality (AR) technology is a field of computer research, which functions by enhancing one’s current perception of reality by the combination of real-world and computer- generated data. The elements of a physical real- world environment are augmented by virtual
computer-generated imagery. Real or fictitious information are ‘mapped’ on to the real world to create new experiences. Currently, most AR research is concerned with the use of live video imagery which is digitally processed and ‘augmented’ by the addition of computer generated graphics.

In 1990 TOM CAUDELL ,a researcher at aircraft manufacturer Boeing, coined the term “augmented reality “ .He applied the term to a head –mounted digital display that guided workers through assembling electrical wires in aircrafts.

Augmented reality is a term for a live direct or an indirect view of a physical real –world environment whose elements are augmented by computer generated imagery. It is related to a more general concept called mediated reality in which a view of reality is modified (possibly diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.

In the case of AR, the augmentation is conventionally in real time and in semantic context with environmental elements, such as sports scores on TV during a match .With the help of advanced AR technology(e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally able. Artificial information about the environment and the objects in it can be stored and retrieved as an information layer on top of the real world view.

The early definition for augmented reality, was an intersection between virtual and physical reality, where digital visuals are blended in to the real world to enhance our perception.
Augmented reality research explores the application of computer –generated imagery in live –video streams as a way to expand the real world. Advanced research includes use of head mounted displays and virtual retinal displays for visualization purpose, and construction of controlled environments containing any number of sensors and actuators.
