| Title |
A Study on the Application of Computers to the Architectural Design |
| Abstract |
The study examined various concepts on the CAD System.With an example of perspective generating computer program, several items, be considered in computer graphics, are introduced.An example data structure of polygon data, line data and point data; homogeneous coordinates transformation for scaling, rotation, translation and perspective distortion; back-facing ploygon removal by the calculation of polygon area for the hidden-line elimination and the final viewport transformation with clipping are mentioned. |
