For providers and customers of wireless communication services such as cellular phone and wireless LAN, to know high frequency electromagnetic wave propagation is concerned with two important matters : one is to know whether we can use the services or not, and another is to know whether our information may be secure or leak by the services. To keep our lives convenient and secure, techniques detecting and showing the propagation situation are useful. We have proposed a beam tracing method with adaptive subdivision, which analyzes and visualizes a propagation situation in three dimensional space. For any point in the object space, power of a propagation is calculated by beams passing through the point, which are defined by a set of three rays. In this paper, an efficient calculation of the power will be proposed, in which the power is not calculated in an area out of sight. The proposed method achieves faster visualization than the previously proposed method, with keeping quality of visualization in a user's sight.
