The huge availability of high-resolution geographical data using the space/air borne platforms has made it possible to create and visualize the three-dimensional (3D) model of any part on the Earth. The seamless visualization of the adjacent data in a mosaic manner not only requires the specialized techniques for data representation but also require sophisticated techniques of rendering to meet the requirements of certain applications like flight simulator, missile path animation. The high speed rendering of the 3D frames is the key requirement in such applications where each frame rendering time is bounded. This paper presents a novel technique for efficient representation of the geographical data covering the complete globe and a new methodology of rendering of 3D frames that guarantees each frame construction within the desired time bound.
