    Abstract: The present invention relates to a method of loading 3-D image data in a navigation system. In the method, whether a vehicle enters an intersection while traveling is determined. A mask array based on a travel path of the vehicle is selected. An object to be displayed at the intersection is selected and a level-of-detail array of the object is selected according to a distance between the vehicle and the object. The level-of-detail array of the object overlaps the mask array. The object is displayed according to a level of detail of the object obtained from the level-of-detail array overlapping the mask array. According to the method, real-time 3-D image data can be loaded in a simple and efficient manner.

    Abstract translation: 本发明涉及一种在导航系统中加载3-D图像数据的方法。 在该方法中,确定车辆在行驶中是否进入十字路口。 选择基于车辆的行进路径的掩模阵列。 选择要在交叉点显示的对象,并根据车辆与物体之间的距离选择对象的细节级别。 对象的细节级别与掩码数组重叠。 根据与遮罩阵列重叠的细节级数组获得的对象的细节级别来显示对象。 根据该方法,可以以简单有效的方式加载实时3-D图像数据。
