説明
It is much simpler and more precise to obtain a configulation factor from the illuminance of calculating points than from the area measurements of the barrel-shaped distorting figure by the orthographic projection.<BR>There are three methods for calculating the illuminance of the calculating points for the basis of the configulation factor:(a) to calculate directly from the value of the coordinates on the inclined surface, (b) to calculate the coordinates of the via-perspective figure obtained from the dimentions of the inclined skylight, (c) to convert the angles measured by the transit into the coordinates of the via-perspective figure.<BR>The operating procedure in the modified integration formula, when calculating the illuminance of the flat surface source in terms of the via-perspective figure, has been altered in accordance with its computerization.<BR>When as above-mentioned calculating to obta in with a mode of seven-figures, which is commonly used in the personal computer, there possibly happens a great miscalculation under a certain condition.<BR>Therefore, the cause and precaution against this miscalculation will be described in the basic program.
