| Popis: | 96 The combined application and presentation of digital technology and cultural field can not only integrate historical research and literature surveys and visually record the deduced results, but can also reserve the historical information of the materials, methods, colors and styles possibly used back then. This paper selects the surrounding area of Fort San Domingo, a first-grade historical site in Danshui, Taipei County, as the historical city space under study. The digitalized files of historical space are established for the message and meaning carried by this studied area, through the analysis and compilation of textual and graphic data. The Virtual Fort San Domingo: Virtual Reality CAVE, is based on the 1983 entity restoration survey report, the 2005 and 2006 digital media data analyses of historical buildings and centers, and the 2005 and 2007 Fort San Domingo historical site research reports, accompanied by Fort San Domingo related research and literature as supports. Field digital photography verifies and compares spatial context and building structure under relevant space-time transformation. The accurately measured drawing plan can meet the precision requirement by transforming it into 3D model with computer technology. Texture mapping is used to represent the entity appearance of the historical building exteriority. The experiment and testing of image processing and color calibration mechanism are necessary to verify the actuality of the image color and scenery. The digitalized and virtualized processes placed in the operation of virtual reality CAVE can become the feasible method for digitalized reservation and conservation science and management of historical building and site conservation. The essence of digitalized conservation lies in permanent preservation. In the domain of historical building and site preservation and restoration, the research evidence of authenticity evaluation is the primary requisite. As to topics related to duplication authenticity, color calibration can display the color of digitalized originals, in which the color cognition is regarded as the scope of sense expression. This paper uses quantified analysis to position the demand of authentic duplication with digital technology. During the digitalized operational process, combining the fundamental concepts of the steps in color calibration and image transformation ensures the color quality achieve considerable degree of accuracy. The testing method proposed which mainly builds upon the preservation application method in the virtual historical space environment, is different from the existing operation of a color checker. The operational processes of historical site and building digitalization and virtualization take into account the conservation concepts to simulate 3D stereo display space. 3D modeling and interactive software are used to make the presentation. In order to satisfy the requirements of authenticity criticism, the degree of refinement and interactiveness of simulation can be enhanced with immersive virtual reality space technology and real-time visual presentation effects. Compared with previous research achievements, this paper incorporates interactive, multi-media and other digital technological elements, which enables free browsing of building structure and exteriority. Joystick can also be used to zoom in the views for careful observation of every corner. This paper utilizes digitalized concepts and techniques to integrate historical site sources with technology for the purpose of conservation and information exchange. The major contributions of this paper include linking digitalization, data visualization and space virtualization with interactive techniques, using Virtual Reality CAVE as the research environment in which the cultural property is placed, and conserving the original appearance of cultures and historical remains more authentically. Accordingly, new results of cultural heritages can better facilitate interactivity production and description of the historical changes. Also, the data can be digitalized so as to support virtualized space. This greatly increases the comprehensiveness of the historical data records. |
