Abstract: Discussed herein is the adequate lighting of a target area as viewed from one or more vantage points to one or more specifications for one or more situations, and in a manner that addresses glare; in particular, glare perception. Various apparatuses, methods, and systems are presented herein whereby glare thresholds are visually indicated. Said glare-indicating apparatus, methods, and/or systems are readily implemented using existing lighting design tools, adaptable in accordance with advances in glare science, and either avoid or overcome limitations of existing glare models. Said apparatuses, methods, and systems can be adapted for real-time evaluation of glare so to, for example, aid a lighting designer in vetting generated (i.e., virtual) lighting designs and identify retrofit options for existing lighting systems.

Abstract: A user interface is provided whereby a user may generate a virtual target area representative of an actual target area, regardless of whether the actual target area has been constructed. Having a generated virtual target area, the user—via the user interface—may generate virtual representations of light to project onto the virtual target area. The virtual representations of light correspond to photometric data from actual light sources. In this manner, the user renders a real-time image representative of what an actual target area would look like illuminated with an actual lighting system. This, in essence, permits a user to evaluate the effectiveness of a lighting system in real time without committing to the purchase of a lighting system.
