Lit-appearance modeling uses ray tracing and visualization

Research output: Contribution to journalArticle


The use of ray tracing, using optical-design software, and visualization in lit-appearance modeling is discussed. The optical-design software is used to trace the rays from source in the illumination system, while visualization software is used to provide the final step for the lit-appearance. Lit-appearance modeling integrates a nonimaging illumination system and an observer to image it, and thus includes a model of the human eye with the lightpipe model. TracePro 3.2 optical-design software from Lambda Research, integrates LightWorks, the photorealistic renderer developed by LightWork Design, England, and provides a quick way to model the lit-appearance of the illumination system prior.
