Radiance is designed to assist lighting designers and architects in forecasting the illumination levels and visual characteristics of a space before it is built. This software package comprises tools for modeling and converting scene geometry, luminaire specifications, and material attributes, all essential for the simulation process. Utilizing ray tracing techniques, the lighting simulation calculates radiance values—representing the amount of light that travels through a specific point in a designated direction—and typically presents these values in a high-quality photographic image format. Users can analyze, view, and modify the resulting images within the software, as well as export them to various widely-used image file formats, thus enabling the creation of printed outputs. Of particular importance to users is the primary component of the Radiance package: the lighting simulation engine, which not only determines light levels but also generates detailed images, allowing for enhanced visualization and assessment of lighting designs. Furthermore, this capability aids in refining the design process by offering insights into potential adjustments before actual construction begins.
