Daylight simulation with photon maps
2005Physically based image synthesis remains one of the most demanding tasks in the computer graphics field, whose applications have evolved along with the techniques in recent years, particularly with the decline in cost of powerful computing hardware. Physically based rendering is essentially a niche since it goes beyond the photorealistic look required ...

Electric lighting consumed approximately 8% of total electricity consumption in the US residential and commercial sectors combined in 2020, accounting for an estimated 6% of total US electricity consumption (EIA, 2021). Reducing electricity consumption while maintaining an acceptable illuminance level is critical to achieving environmental ...

Comparative Evaluation of Daylighting Simulation Programs
Applied Mechanics and Materials, 2016Daylighting simulation programs use different methods and algorithms for illuminance calculations in buildings. It is widely known that results of different lighting simulation programs does not have to be the same for two or more identical rooms. Hence CIE issued Technical Report 171: 2006 which presents test cases to assess the accuracy of lighting ...

Color scales in simulated daylight
Color Research & Application, 1981AbstractThe pigmentation plan used for production of the color cards made available by the Optical Society of America (OSA) for its Committee on Uniform Color Scales (UCS) was designed in such a manner that the color scales should, within the production tolerances, appear uniform in all phases of daylight.

Comparison of Experimental and Simulation Data for Daylighting
2018 Seventh Balkan Conference on Lighting (BalkanLight), 2018The paper detailed information about experimental results, obtained for the Daylight Factor (DF) of an educational facility. The experimental data obtained is compared to computational results, given by different software products for lighting calculations. The correlation between the measured and the simulated data is estimated.

Daylight prediction: an evaluation of daylighting simulation software for four cases
2015The use of daylighting to supplement and offset artificial lighting requirements in interior spaces is an important step in achieving California?s current and future energy goals. The analysis of daylighting is not only difficult for lighting designers, but also the results are not always accurate.

Coloration Technology, 2003
This paper discusses two methods for evaluating the quality of daylight simulators, namely the band‐value method specified in British standard BS 950 and the CIE metamerism index method. Six daylight simulators of various types and manufacturers were used for the assessment and a psychophysical experiment was conducted to evaluate the two methods.

Simulation of daylight for viewing and measuring color
Color Research & Application, 1994AbstractFor convenience and reproducibility, daylight is artificially simulated for viewing and measuring colors. Daylight has been standardized in a way that is impractical. the evaluation of fluorescent materials requires simulation of the ultraviolet component of daylight or daylight through a window.

Colorimetric evaluation of daylight simulator sources
Color Research & Application, 1995AbstractThe color shift of a sample due to a change in illuminant can be expressed either in terms of the CIE General Color Rendering Index, Ra, based on the average for eight color samples, or in terms of the CIE Metamerism Index MIvis, the average for five pairs (or couples) of samples.
