Abstract Ray-tracing technique is an efficient method to analyse the propagation in urban and indoor environment, but there are still many questions which need to be studied while realizing. In this paper, octatree technique which was first used in computer graphics is used in ray-tracing, and the ray-tracing efficiency is improved.
