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.

- Although, as mentioned earlier, Radiance can be a difficult system to
use, I believe that it is a very powerful tool which will reward those
that persist in coming to grips with it. If you, like me, find the
illumination models used by the majority of rendering applications
unsatisfactory then I strongly suggest giving Radiance a close look,
especially for architectural modeling since its radiosity/ray-tracing
hybrid approach is capable of producing very convincing images.
