RADIANCE 프로그램과 인터넷 환경을 이용한 조명시뮬레이션 시스템 개발 = Developing a Lighting Simulation System using the RADIANCE Program and Internet Environment

다국어 초록 (Multilingual Abstract)

The prediction of illuminances from daylight and artificial lighting has been an important issue in the field of architecture. Architects traditionally have used scale models or various computer programs as tools for predicting the available illuminance in a building and for visualizing the overall lighting quality of the environment. The program requires accurate modeling of the geometric and photometric properties of a designed environment.
RADIANCE is a program developed to aid lighting designers and architects by predicting the lighting levels and appearance of a space prior to construction of a building. The modeling of geometric property is usually conducted by commercially available CAD softwares. The modeling of photometric properties includes material color, texture and/or transmittance, daylight availability, and luminous intensity distribution of artificial light sources. The simulation itself uses backward ray-tracing technique to compute radiance values, which are typically arranged to form a photographic quality image.
The purpose of this study is to develop a Radiance rendering system that operates automatically on the WWW environment.
