1、Perspective on virtual reality,Presented By:Ali Sedki,By: Architecture Week,Web Address:,Topic Number: 127,Date: 11 September 2002,10/9/2022,1,Perspective on virtual reality,INTRODUCTION,From the 15th century through the 20th, architects worked with evolving techniques for presenting their designs t
2、o their clients. In the 1990s, this evolution seemed to quicken its pace with advances in computer modeling, animation, and virtual reality. In their book, Artists Impressions in Architectural Design, authors Giddings and Horne trace these developments, ending with a survey of the work of leading ar
3、chitects using computer-based technologies.,10/9/2022,2,INTRODUCTIONFrom the 15th cent,Modeling,Throughout the 1990s, a type of animation that attracted much attention was the pre-recorded architectural walkthrough. This technique involved building scenes using geometric objects and enabling users t

This simulated the effect of walking around a building or area and experiencing the feel of the environment.,The exterior images of Old Town Hall, North Shield,10/9/2022,3,Modeling Throughout the 1990s,Animation,The exterior and interior images of Old Town Hall, North

A technique that proved interesting to architectural practice was one that allowed inte

The method involved taking a 360-degree photomontage and mapping it to the interior of an imaginary sphere.,10/9/2022,5,Virtual Reality By the early 1,Virtual Reality,Combinations of photographs and 3D models could be used, and the view of a person standing inside t
8、he sphere was a surrounding display of a real or virtual environment.The Apple QuickTime VR system became established in this area and allowed the creation of 3D virtual worlds and interactive presentations on Macintosh computersSurround Video software was the Microsoft Windows equivalent.,10/9/2022

A significant development for architects was Virtual Re
10、ality Modeling Language (VRML), a programming language for the definition of Web-based 3D worlds. Software was developed specifically to model and display VRML worlds.At the beginning of the 21st century architects increasingly used Web technology to display their projects. Through a Web site, clien
