A Guideline for Virtual Reconstruction of Historical Facades, 3D Projection Mapping Approach

ABSTRACT: During this study historical buildings and different types of lighting on historical facades are introduced, in general, and then specifically, 3D projection mapping on the facade of historical buildings, in order to create a context for proposing a new idea to apply this technique on the historical facade. Through the study the capabilities of 3D projection mapping on historical facades in artistic exhibitions was investigated. The researcher uses capabilities such as high quality of lighting, presenting realistic images, masking capabilities, as well as high clarity of the images from the distance for suggesting an innovative method for reconstructive purposes. Visual reconstruction of the historical facade as a new suggestion contributes to the preservation of the identity of historical buildings which utilizes a 3D projection mapping to display the reconstructed image of the facade of the historical building onto the facades with high quality and 3D method. The present study seeks to introduce a new guideline for the implication of 3D projection mapping in absorbing the audience to reconstructed building virtually. 3D projection mapping has been used commonly for projecting images onto the facade of buildings by using light to revive the historical context. This technology has the ability to operate new functions as a media for creating a relation between the building and the viewers. Video projection mapping works are categorized into several types such as the methods of projecting onto buildings; the present study attempts to propose a guideline for using 3D projection mapping and categorize it in artistic or entertainment, advertising and specifically reconstruction. iv Keywords: Historical Facade, Visual Reconstruction, 3D Projection Mapping, Virtual Facadism. …………………………………………………………………………………………………………………………
