INTRODUCTION

3D Internet makes virtual communities and collaboration being and

doing together possible. 3D Internet is the next wave after the

current 2D web. 3D Internet consists of interconnected services,

presented as virtual worlds. Virtual worlds are 3D environments user

enters with his avatar. Virtual worlds may be considered as advanced

web sites and avatars as user profiles. The difference lays in

collaborative content creating where user is part of building his virtualexperience together with other users avatars and service provider.

Imagine a set-up of interconnected virtual worlds inhabited by users

who can visit and consume services through teleporting from one

world to another.

3D Internet will rely on the same basic technology and components as

that of a traditional browser, and it will interact with the same search

engines and servers. Aside from the use of 3D computer graphics and

personalized avatars, the important difference lies in a much more

social experience compared to the 2D internet of today.

3D internet is incredibly social. If you are reading a document, you

can see other people reading the same document. You connect

organically with other people that share your interest and consume the

same services that you do.

3D WEB TECHNOLOGIES

VRML(also known as the Virtual Reality Markup Language) is

a standard file format for representing 3D interactive vector

graphics, designed particularly with the World Wide Web in mind.

X3D - features extensions to VRML (e.g. CAD , Geospatial

, Humanoid animation, NURBS etc.), the ability to encode the

scene using an XML syntax as well as the Open Inventor-like

syntax of VRML97, or binary formatting, and enhanced

application programming interfaces (APIs). X3D extension

supports multi-stage and multi-texture render; it also supports

shader with light map and normal map.

WebGL - (Web Graphics Library) is a JavaScript API for

rendering interactive 3D graphics and 2D graphics within any

compatible web browser without the use of plug-ins. WebGL is

integrated completely into all the web standards of the browser

allowing GPU accelerated usage of physics and image processing

and effects as part of the web page canvas. WebGL elements can

be mixed with other HTML elements and composited with otherparts of the page or page background.

WebGL programs consist of

control code written in JavaScript and shader code that is executed

on a computer's Graphics Processing Unit (GPU).

COLLADA - defines an open standard XML schema for

exchanging digital assets among various graphics software

applications that might otherwise store their assets in incompatible

file formats. COLLADA documents that describe digital assets are

XML files, usually identified with a .dae (digital asset

exchange) filename extension.

APPLICATIONS

E-commerce - is a type of industry where the buying and selling

of products or services is conducted over electronic systems such

as the Internet and other computer networks. Electronic commerce

draws on technologies such as mobile commerce, electronic funds

transfer, supply chain management, Internet marketing, online

transaction processing, electronic data interchange, inventory

management systems, and automated data collection systems.

Education - virtual field trips

- distance education as well as on-campus

- virtual experiments for physical sciences

- historical recreations for social sciences

- 3D data visualization for various fields

Gamesmulti-player, fully 3D (eg. Sony Everquest)

Social Interaction3DChat Spaces

Entertainment - streaming 3D animation (much lower bandwidth

than video, can run full-screen, can have interactivity).

ADVANTAGES

Participants have control throughout Virtual Space.

Content is easily available.

Participants have choice whether to interact with an offering.

Combines the immediacy of television, the versatile content of the

Web, and the relationship-building strengths of social networking

sites likeFace book.

Interactive and engaging, falling costs.

CHALLENGES

Advertisers, marketers and organizations have yet to capitalize on the

vast potential of the 3D Internet. The limited effectiveness of

traditional media techniques such as fixed-location billboards when

applied to virtual worlds. In the 3D Internet, participants have

complete control over where they go and what they do and can

move their avatars instantly through virtual space. What is required is

a means for making content readily available to people not only at

specific points, but throughout virtual worlds. Lack of an effective

way for enabling people in virtual worlds to encounter commercial

content that enhances their virtual experience. Because participants

have a choice in whether to interact with an offering, it is essential


7/7

that it be viewed as relevant and valuable to their particular goals in

the 3D Internet. An inconsistent means for enabling in-world

participants to easily interact with and access video, rich multimedia,

and Web content. The lack of a cohesive means for advertisers and

content providers to receive the detailed metrics required to measure

success.

CONCLUSION

3D Internet is a step ahead to the future which could serve for not

only as fictional virtual world but will change the way we perceive

internet of today.
