What is RADIANCE?

RADIANCE is a highly accurate ray-tracing software system for UNIX computers that is licensed at no cost to users for non-commercial use; commercial use licenses including distribution rights are available for a fee. Radiance was developed with primary support from the U.S. Department Of Energy and additional support from the Swiss Federal Government. It is copyrighted by the Regents of the University of California.

Short description

Radiance is a suite of programs for the analysis and visualization of lighting in design.

Input files specify the scene geometry, materials, luminaires,time, date and sky conditions (for daylight calculations). Calculated values include spectral radiance (ie. luminance + color), irradiance (illuminance + color) and glare indices. Simulation results may be displayed as color images, numerical values and contour plots.

The primary advantage of Radiance over simpler lighting calculation and rendering tools is that there are no limitations on the geometry or the materials that may be simulated. Radiance is used by architects and engineers to predict illumination, visual quality and appearance of innovative design spaces, and by researchers to evaluate new lighting and daylighting technologies.
