However, most architects limit the use of computers to drafting and documentation purposes. This study demonstrates the use of computer graphics as a viable alternative to traditional visualization and communication methods in architecture. The thesis is presented in two parts. The first part comprises of case-studies which demonstrate how architects have successfully used computers as a tool for visualization and communication. It also reviews the underlying concepts and components of visualization, providing readers with the necessary background. The second part of the thesis demonstrates with the help of an example, the construction of a 3D model and how to render and animate the model. In doing so, this study reviews the tools associated with the given discipline. Today’s technology brings the promise of incredible communication powers to virtually anyone interested in presenting a message. This study helps architects and designers in understanding what the technology can do. It assists them to choose the right tools for the job. And most importantly, it guides them in using the technology and the tools for effective communication and visualization in architecture. ACKNOWLEDGMENTS This achievement is dedicated to my parents, and Parul, whose invaluable love, support and encouragement have made this project possible. I would like to give my special thanks to my committee chair Dominique Bonnamour Lloyd, without whose support, guidance and expertise it would not have been possible to complete this project I would like to thank my committee members. Professor Robert Dvorak, for his knowledge, and understanding, and for helping me throughout. Professor Oscar Blazquez for his suggestions, and interest. I would also like to thank Fred Matter for his cooperation. Finally special thanks are due to Ashish, Shefali and other friends in the graduate studio who have given me courage, comfort and unforgetable memories. TABLE OF CONTENTS Chapters Page 1.

INTRODUCTION For centuries, architects have carried out shape computations by hand, using informal procedures and the simplest of tools. Over the last two decades, though, they have made increasing use of more formal procedures executed by computers (Mitchell, 1991). It is still too early to be sure of the gains and losses that result from this development, but undoubtedly this raises some challenging questions of architectural theory and some perplexing issues for those concerned with the future of architectural education. If multimedia can be defined as communication through more than one medium, then architects have been multimedia experts for centuries (Jeff Burger, 1993). Buildings structures are complex, visually, technically, and functionally, so designers have always described them through a variety of drawings, scale models, and writings. These traditional methods of communication have several drawbacks. With the advent of computing technology, new tools have been developed for communication and visualization in architecture. Preference should be made for computer graphics in architecture as an active tool
