Abstract

This paper presents an efficient visibility method based on OpenGL in large-scale urban environment. Due to the full 3- D environment of macro cell, visibility judge will contain huge amount of buildings and environment information, which means extremely high computation time for traditional method. The model established by accurate digital map, depth test and color buffer is used here to assist in visibility judge, which the location and the height of antenna are of great important. This method is suitable for three-dimensional simulations.
