What is Radiance?
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.
Radiance is free. Supported Platforms are: SGI, SUN
