| Abstract |
Many architects choose to begin projects using paper and pencil only to transfer that material to a computational environment for final polishing and presentation. This phenomenon can be credited to a prevalent misconception about the inherent nature of computer graphics: that digital tools inherently demand a high level of precision and a lack of ambiguity. The motivation behind this study is a desire to bridge the gap between initial sketching and digital design environment. This study presents a process exploring four methods for generating three-dimensional coordinates and digital model. The first method is digital image processing techniques by which the skeleton of feature is extracted. The second method makes use of an old machine vision algorithm, the Kanade labeling scheme. The third method is neural network recognizing edge point types and the last one is Active X control which enable mined data from previous steps to be manipulated in various ways. This study tends to present progressed vector conversion model of sketch and tries to find the meaning of CAAD system as design media in architectural concept. |
