Originator of Virtual Reality - VRML (directory)


I. What is VRML

We can imagine such a scenario: When you wear a special helmet and gloves, you find yourself in the midst of a museum, when you walk forward or turned around, you saw the picture will changeYou can cross the hall, opened the front door; and when you see a beautiful exhibition, you can even up and down, inside and watch carefully this is virtual reality .......--- bring you to all the real feeling of near-perfect.

Second, VRML history

May 1994, in Geneva, Switzerland World Wide Web (www) meeting, Mark Pesce and Tony Parisi gave a presentation on their development can be run on the World Wide Web Virtual Reality interface.At this time, who by the Association BOF a fun companion for a strong response right away, decided to develop a scene description language, which can be connected Web Network.The term VRML BOF meeting is made out of.(BOF from an English proverb: Birds of a feather.)

Third, VRML syntax

The concept at the highest level, VRML is a description of the virtual object file format.In principle, objects could include anything - three-dimensional geometry, MIDI data, MPEG image and so on.VRML defines a set of objects used to implement three-dimensional scene, multimedia and interactivity.These objects are called "nodes" (Node), the node contains the basic elements of a "domain" (Field) and the "event" (Event), the domain is the node that contains the parameters, events for the parameters of the transfer.

Fourth, VRML visualization tools

For VRML enthusiasts, the current lack of a good writer VRML virtual reality is a big problem in itself need only three-dimensional modeling and abstract artistic creativity, but because of the current computer software in this regard the lack of technical support, making virtual realityMaking VRML prepared to face dry, take those numbers and three-dimensional model of link is a very difficult task.

So in the end there is no visualization of VRML editing tool?

V., VRML application and development prospects

With the popularity of the Internet, network technology and the rapid development of hardware, virtual reality technology will become the mainstream of networked multimedia development.VRML as an ISO International Standard will be more widely used.
