Comparison of lighting simulation tools with focus on lighting quality
By the rise of concerns for global warming, reducing emissions via lowering energy consumption has become a necessity in every sector and the lighting sector is no exception. However, it should not come at the cost of lighting quality and user comfort which is a common practice in today’s lighting design and energy reduction initiatives. The “energy reduction” view should change toward “value d...
متن کاملApplications of Image Based Rendering in Lighting Simulation: Development and Evaluation of Image Based Sky Models
This paper demonstrates the use of High Dynamic Range (HDR) fisheye images of the sky dome in lighting simulations. The objective is to improve the accuracy of simulations with site specific sky conditions. The luminance information stored at a pixel level in an HDR photograph is used to light the simulated environment through an Image Based Rendering (IBR) technique. The results show that imag...
متن کاملEvalution of High Dynamic Range Image-Based Sky Models in Lighting Simulation
High Dynamic Range (HDR) Photography is used to capture 180 images of the sky dome and provide data for image-based lighting in lieu of CIE sky models.
متن کاملEvaluation of High Dynamic Range Image Based Sky Models in Lighting Simulation
Daylight availability and sky luminance distributions vary spatially and temporally depending on geography, weather, and other local conditions. Substantial amount of data is accumulated from long term measurements in various parts of the world (Kitler et al. 1992) through sky scanners. These devices (such as the Krochmann sky scanner) typically measure luminance at 145 points. The accumulated ...
متن کاملMid-infrared all-sky survey with AKARI
AKARI (formerly called ASTRO-F) is the first Japanese astronomical infrared satellite and it is now in a sun-synchronous polar orbit at the altitude of 700 km. One of the major programs of AKARI observations is an all-sky survey in the midto far-infrared spectral region with 6 photometric bands. AKARI has a 685mm telescope, which is cooled down to about 6K by superfluid liquid helium and mechan...
