LIGHTING ANALYSIS
Charlotte, North Carolina
Radiance Analysis

“Radiance is intended to aid lighting designers
and architects by predicting the light levels and
appearance of a space prior to construction. The
package includes programs for modeling and
translating scene geometry, luminaire data and
material properties, all of which are needed as input
into the simulation. The lighting simulation itself
uses ray tracing techniques to compute radiance
values, which are typically arranged to form a
photographic quality image. The resulting image
may be analyzed, displayed, and manipulated within
the package, and converted to other popular image
file formats for export to other packages, facilitating
the production of hard copy output.”
