概要

We have established a visualization system for spatial illuminance, in order to visually recognize the three-dimensional luminous condition in a lighting space. It calculates illumination vector and mean spherical illuminance at every point on a regular grid, and displays them graphically with perspective. This paper describes the simulation and analysis of the luminous environment of a soccer ground and an interior, including the spherical presentation of mean spherical illumninance distribution, color contours of mean spherical illuminance distribution on a certain 2-D section, perspective display of pointing arrows, and isosurface of mean spherical illuminance. These readily understandable presentations enables us to lay the foundations for applying spatial illuminance to the analysis of lighting conditions.
