Abstract |
The curve of a roof is one of the distinctive external characteristics in traditional buildings of three far-eastern countries. Nevertheless, it has not been easy to identify and classify various roof styles. With the advance of culture technology, it becomes necessary to devise a mathematical method how to methodologically characterize the roof curve of traditional buildings. In this context, we explored, through differential geometric techniques, how a roof curve could be formulated by a discrete curvature. Discrete real data is corrected by numerical analytic method and discrete curvature is computed. The outcome of the research could be used to systematically describe and categorize roof curves to regenerate them in cyber world primarily for 3D rendering or animation of traditional oriental buildings. |
