Architects create their architectures. As the way of architectural presentations, there are drawings (plans, elevations, sections...), perspectives, models, and etc. In the past, these drawings are made by humans with handwriting, but recently we can get the most part of them by using computer. Computer graphics techniques can generate architectural perspectives. Useful examples of computer perspectives are followings : (1) idea sketches (2) optical emvironmental simulations (3) finish material simulations (4) design and color simulations for interiors and furnitures (5) exterior simulations (6) architectural environmental simulations (7) presentations Many display devices and algorithms are developped for Computer graphics. CRT is the most important device for display perspectives. Typical examples of CRT are random scan refresh CRT, storage tube CRT, and raster refresh CRT. About softoware, important algorithms are depth sort algorithm, z-buffer algorithm, scan line algorithm, and ray tracing algorithm. Halftonig techniques for using display with a limited range of output values are halftone patterns, dither method, PSET 4 subroutine, and etc. Precise image communication isn't procecuted using only handwriting drawings. As desigin goes, the architectural image sets shape. Thers is a limit to the drawing presentations. In order to communicate the architect's image precisely we need perspectives or models. Therefore the perspectives must present the image as real as possible. The perspectives generated by computer are sutable for such use very match. Especially the ray tracing method can generate the most real image.
