Introduction

Architectures with organic surfaces or with sculptural forms are defined as Free Form in our lab. The use of computer is not the sole reason of this definition but is the new way to make the design and construction of it more and more easy and quickly. In order to discover the digital processes of constructing Free Form Architecture, Pro. Liu set up the research project supported by the Far Eastern Group. The first of our research result has been published in A+U 383, and this is the second time we dedicated in this issue. Not only the CAD-CAM technology, which was used in the first experiment, but also the membrane technology is used this time. The result of the experiment is used as an exhibition place of FEIDAD Awards.

Introduction

In this research we give up the traditional ways of simulation but use a new technology, which is commonly used in entertainment industry, called “Camera Matching”. Using camera matching can shorten the time and reduce the efforts of producing simulations. Further more, collaborative Design through digital media environment, such as VR Cave and Internet, is the other ways we explored during the research project. Using VR Cave with Internet connection can make the discussion more effective. The results of the technology are highly proved by professions. In these simulations, we not only show the concept of Digital Art City, but also push it as public policies.

Introduction

Computer simulation technologies were used well in virtual archaeology during the past five years but will be insufficient gradually in the future, just because the simulations have extended from static issues, such as implements, architectures and a whole city, to motional issues, such as cultural activities in a city. So we tried to developed a digital reconstruction procedure that integrated three main technologies including 3D scanner, motion capture and virtual reality cave (VR Cave), and implemented it to reconstruct Chang-An City that existed 1400 years ago but disappeared now. This is an interdisciplinary project, and is also my first time to lead a research team including over 15 members from 6 schools. The results of the simulations are not only realistic enough, highly approved by archeologists, architects, and scholars of art, but also able to influence the deduction processes.

Introduction

The Chi-Chi station is a very important historical antique in Taiwan that was heavily destroyed by the 921 earthquakes in 1999. In order to recover this important transportation node within a very short period of time, we adopt computer simulation techniques to assist from the late-design (3D-shop drawings) phase to the actual construction stage. During the process, we propose two research issues to discover: 1) How to represent the knowledge of reconstruction of the main craftsman by means of sequential animations? 2) How do these sequential animations actually work as an assistive media during the process? The objective of this research is to propose an effective process of retrieving sequential knowledge. Eventually, we find out that the computation enhanced construction process is definitely much more effective and efficient comparing to those of conventional design and construction tools.

Introduction

In the past, computer simulation is used in architecture field as the presentation of architects, but most common people always indicate that they don’t understand the purpose of architects showed in the pictures or animations without explanation. An issue is propose here that how can we conduct more readable computer simulations. This project attempts to apply the up-dated computer simulation techniques, called scenario scripting, into the historical area of Hsinchu and the 18-peak mountain regional park. We not only combine roles with the design strategies during the design phase, but also represent the images of roles in the computer simulation. The assumption that people will be well located by seeing the image of the roles in the simulations finally proved by the experiment. During this project, we also creat a huge digital archieve of a whole city effectively.

Introduction

In the past of Hsinchu, the management of urban planning and historical reservation was not effective, so that the urban lost its activity and potential. That is why this project is set, and two solutions which are urban renew and preservation of historical culture are proposed. In order to achieve these goals, we try to focus on two subjects: First, the renewal of historical building and street furniture in the city. Second, the lighting design of historical buildings and main streets. We use computer simulation technologies, which includes modeling in Form Z enviornment, texuring and rendering in Light Wave, and animating in 3D Max, to assist plan, design and communication.
