Abstract: Sustainable building lighting and energy modelling and control, and the associated computer graphics, including real-time dynamic lighting simulation, are concerned with: an optimized method for radiance modelling, including its application to predictive daylight harvesting; and the real-time simulation of physically-based electric lighting and daylighting for architectural, horticultural, and theatrical lighting systems visualization. In order to display and analyze in real time a photometrically accurate representation of an environment, thousands of lighting channels may have their intensity settings continually varied such that a user may interactively view the three-dimensional environment without the need for ongoing global illumination calculations. This can be accomplished utilizing texture maps as a multiplicity of canonical radiosity solutions, each representing a lighting channel for dynamic lighting simulation, and storing the solutions in the texture memory of a graphics processing unit.

Abstract: In an example, an expected sky condition is calculated for a geographic location, a time of day, and a date based on a mathematical model. A predicted distribution of direct and interreflected solar radiation within the environment is calculated based on the expected sky condition. Measurement data from one or more photosensors is obtained that provides measurements of an initial distribution of direct and interreflected radiation within the environment, including radiation from solar and electrical lighting sources. A target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting is determined, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, to achieve the target distribution of direct and interreflected radiation within the environment. Output parameters are set to one or more devices to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment, including diffusion characteristics of the materials between environments.
