Abstract:In this paper, as a background of three-dimensional electronic map, we present a program to design and implement a three-dimensional scene manager, which can organize and manage the entire scene effectively, via optimized Octree. And then, on this basis, we reproduce the scene on the Android platform through native OpenGL ES graphics library. A new space division method, which is based on models' spatial features, will be presented later. After experiments, consequences confirm that this method can avoid unnecessary memory overhead to some extent, so it has the possibility of more conducive to application in embedded devices with the relatively limited resources.
