The present invention relates to a method for guaranteeing real-time by providing an optimal speed in rendering the three-dimensional terrain on the screen, in the three-dimensional terrain rendering, the distance from the viewpoint at the time of rendering after the terrain storage in the intermediate level of detail According to the present invention, the first rendering step is to divide and render polygons when the terrain is close to the viewpoint, and the second rendering step to reduce and render polygons when the terrain is far from the viewpoint. By controlling the number of textures without burdening the CPU, the rendering performance is maximized, and the texture improvement for the distant terrain is maximized for the performance improvement. |
