최근 야간 경관조명의 설치가 늘어나면서 조명 시뮬레이션에 Lightscape를 적용하는 사례가 증가하고 있는 추세이다. Lightscape는 현재 조명 시뮬레이션에 가장 널리 사용되고 있는 소프트웨어로서 조명설계에 따른 조도와 휘도 분포를 계산할 수 있으며, 에니메이션이 가능하다. 에니메이션은 Radiosity를 사용한 화면은 물론 photorealistic한 고화질의 Raytrace영상이 가능하다. 본 보고서에서는 최근 건축물이나 구조물의 설계입찰시에 조명 시뮬레이션은 물론이고 에니메이션 파일의 제출요구가 증가하고 있는 점을 감안하여 Lightscape의 에니메이션 기능을 Learning Lightscape를 중심으로 설명하고 상세한 설명이 요구되는 곳은 Lightscape User's Guide를 발췌하여 소개한다. 또한, 본문의 내용은 Lightscape을 사용하는 것을 전제로 하고 있으므로 "3. 에니메이션 생성" 부분부터는 컴퓨터에서 직접 실행해 볼것을 추천한다.

Computer simulation is one of the most useful techniques to predict daylighting performance and present visual image. In architectural and interior design practice, the Lightscape is commonly used often to produce persuasive images rather than physically accurate results. Therefore, this study is to validity the Lightscape as daylighting evaluation tool, in particularly performance and realistically visualization. For the purpose, an evaluation test model (12.0m$\times$7.2m$\times$3.0m) of side lighting window with lightshelf was selected. A 1:6 scale plywood physical model was made. Under clear sky condition, illuminance of 84 Interior point were measured. Lightscape was run on a 750 MHz Pentium PC running Windows 2000 under the same sky condition. And a photography image was compared to rendering image. The physical results of interior illuminance were within 8% between the scale model and Lightscape simulation. There were no differences between the photograph image and rendering image by Lightscape in the sight. Lightscape as visualization tool for daylighting performance was validated.

This report compares illuminance of formula with the one of the Lightscape which is lighting simulation system, and applied IES file to the Lightscape by angles and coordinate. As a result of correct solution in comparison, we got a satisfactory result from this study. We effectively hope to make the road lighting calculations through the collection and preparation for the lighting data in detail.

Lightscape is a visual rendering software enabling higher dimensional 3D image production using rendering as well. However, direct light simulation showed that more realistic feature of material-specific texture or color could be achieved by adjusting options. Accordingly, this study is to generate optimal values of options and achieve more realistic images by varying such values according to individual materials in order to create better quality simulation images using Lightscape.

야간 경관조명을 계획 및 평가하는데 필요한 물리량의 측정기법이나 컴퓨터 시뮬레이션의 유효성에 대한 검증이 미흡한 상황이다. 이에 본 연구 경관조명에 많이 사용되는 대표적 프로그램인 Lightscape 3.2의 유효성을 Radiant Imaging ProMetric 1400을 이용하여 검증한 것이다. 교량의 7개 부분에 대한 평균 휘도값을 비교한 결과 Radiant Imaging ProMetric 1400에 의한 물리량 측정값과 Lightscape 3.2의 컴퓨터 시뮬레이션 값 사이에는 상대오차율이 평균 8.3%로 나타나, Lightscape 3.2가 경관조명의 사전 시뮬레이션 도구로써 매우 유효한 것으로 나타났다.

This study is to generate optimal values of brightness and achieve more realistic images by varying such values according to individual materials in order to create better quality simulation images using Lightscape. Because there are discolorations of materials by adding the radiation of luminaires to that of daylight during the daytime, when low brightness values are inputted in case of daytime, the results are founded that images of materials can be seen much similar with real images. And in most of the materials, when low values in the daytime and high values in the nighttime are inputted this study verifies that the realest simulation images can be obtained using Lightscape, because the RGB data of simulation images are almost similar with that of real materials.

This report investigates the road lighting systems by using the road lighting simulation system which is the 'Lightscape', and compares the result of the simulation with criterion of the road lighting system. The solution of that is almost equal to the criterion of the road lighting system. With this simulation, we hope to accurately investigate the criterion of the road lighting systems and design the road lighting systems effectively.

This thesis is a study on the exactitude of Simulation Tool by using illuminate formula. Lightscape looks like general 3d program, but is a lighting simulation program that set up the properties of materials and light-sources about the model. This thesis calculates illuminance by a formula and simulates a light simulation using Lightscape for two luminaires data in space of ideal environment. As then each value was compared. As a result we got an error under 1% on the whole.

Simulation of daylighting by computer program is a method to avoid unnecessary efforts in manufacture of its testing models, to reduce its measuring tolerances and be able to provide variations of various weather conditions as well. Many simulation programs on daylighting have been released freely or commercialized for selling, however, a demonstration of their availability and validity as a tool for evaluating daylighting performance is required since each one has its own characteristics. The objectives of this study lie in suggesting an application method of evaluation tools and demonstration of limits and characteristics so as to more easily determine the daylightingperformance in the very initial stages of planning for an arbitrary office space in which windows with daylight access are built. We produced scale model of the general light inducing type side lighting with lightshelfand ceiling, and the luminance (at 78 measuring points) and illuminance (at 84 measuring points) were measured in a clear sky. And a comparison of the measured values and the calculated values from a computer simulation using the Lightscape program was performed.
