광선추적 기법을 이용한 가시영역 분석에 관한 연구

Abstract

The purpose of this study was to get over limit from the way of two dimensional vector analysis and to establish intuitive analysis method considering 3D environment in the analysis of space experience as movement and visibility. First, this study suggested the way of calculating the visible area which extracts shadow from a light by using 3D modeling and Raytracing. It is possible to analyze qualitatively through the form of M-map, IV-map, OV-map images and to analyze quantitatively as extracting the pixel information each map has. The study can predict both the possibility of horizontal movement and vertical movement at the same time through the information which M-map, IV-map, OV-map have. Also, the study allow to analyze the visible area according to the opening's size and shape in the analysis of visibility and the change of the visible area according to the material's transparency and refractive index. This method will be helpful to analyze the informal form buildings which have many curves and the space of modern buildings which use a variety of shape's glass.
