VIRTUAL ENVIRONMENT (VE)

A computer generated world with which the user can interact

Interaction can vary from looking around to interactively modifying theworld.

WHAT IS IMMERSIVE VR?

Atype ofVR in which the user becomes immersed (deeply

involved) in a virtual world. it is also a form ofV

R that usescomputer related components.


12/33

Text-basedVR:when a reader of a certain text form a mental model of thisvirtual world in their head from the description of people , places andthings.

AugmentedVR:the idea of taking what is real and adding to it in some wayso that user obtains more information from their environment.

ARCHITECTURE


15/33

ARCHITECTURE

An area in which virtual reality has tremendous potential is inarchitectural design.Already being created are architectural"walkthroughs that allow designers and clients to examine

homes and office buildings, inside and out, before they'rebuilt. With virtual reality, designers can interactively test abuilding before construction begins.


16/33

MEDICAL

The medical application ofVR was stimulated initially by the need ofmedical staff to visualize complex medical data, particularly duringsurgery and for surgery planning, and for medical education and training.

Teach new skills in a safe, controlledenvironment

TRAINING


18/33

TRAINING

United States: The military used it as flight simulatorsto train pilots.

National Aeronautics and Space Administration (NASA)use VR technology to construct a model of the HubbleSpace Telescope (HST) .in September, 199 ,approximately 100 members of the NASA HST flightteam received over 200 hours of training using the

VR...

DEVICES

Head Mounted Displays (

HMD):

was the first device providing itswearer with an immersiveexperience. Evans and Sutherlanddemonstrated a head-mounted

stereo display already in 1965.

BINOCULAR OMNI-ORIENTATION MONITOR

(BOOM)

BOOM is a head coupledstereoscopic display device.Screens and optical system are

housed in a box that is attached toa multi-link arm.

CAVE AUTOMATIC VIRTUAL

ENVIRONMENT (CAVE)

y Aroom with projections on all walls, floorand ceiling

y The users wear shutter glasses to get a Dview of the world.

y The users are able to move and control theenvironment with some kind of inputmechanism

y Camera

VIRTUAL REALITY MODELING LANGUAGE

(VRML)

Most exciting is the ongoing development ofVRML on theWorld Wide Web. In addition to HTML (Hypertext MarkupLanguage), that has become a standard authoring tool forthe creation of home pages, VRML provides three-

dimensional worlds with integrated hyperlinks on the Web.Home pages become home spaces.


23/33

BAM AND ITS CULTURAL LANDSCAPE

After the earthquake of the 26th December 200 andthe immense destruction of the Bam heritage in Iran,the reconstruction of the ruins especially of the citadelof Bam has become an important task for experts.

first phase of the project were to develop theDimensional models


24/33

CONT.

The team of drawing the Dmodels consisting of in Japan from WasedaUniversity and the team of RaazAhangarchitectural firm in Iran fromUniversity of Tehran has made a tremendous effort to build the D

models.

FUTURE

1999 10% of the world's computing power was non-human

2029 99% of the worlds computing capacitywill be non-human

In the past, computing power has doubledapproximately every 18 months, a trend that is known asMoores Law. If this is the case then we should have a

computer powerful enough to run immersive VRprograms in our own homes by the year 20 7.
