Radiance

Radiance is a suite of programs for the analysis and visualization of lighting in design. It employs advanced Monte Carlo ray-tracing with optimizations for complex building geometries and fenestration systems.

Radiance

Radiance is used in windows software tools for the calculation of optical properties of optically complex window products, including light-redirecting glazing and films, shading products, etc. Special module called genBSDF is used for this purpose.

Radiance is also used for rendering rooms in COMFEN and Berkeley Lab WINDOW software tools, based on the choice of window and/or shading products. It is also used for creating room luminance maps used in determining glare and daylight availability.
