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