    • A road map rendering method and associated computing apparatus are provided. The method includes: receiving data representing a road broken line, the data including multiple line segments and a road traffic condition; expanding the road broken line into a polygon based on the multiple line segments and creating a geometric-topological structure for the polygon using the received data, the geometric-topological structure including a vertex list and an index list; selecting texture coordinates that correspond to the road traffic condition; and filling the polygon using the selected texture coordinates that correspond to the road traffic condition. In the road map rendering method and associated computing apparatus provided in the embodiments of the present application, a road traffic condition is rendered by invoking a texture, so that performance of a graphics processing unit of a mobile terminal can be exploited and a good rendering effect can be achieved, thereby clearly indicating the road traffic condition.
    • 提供路线图绘制方法和相关联的计算装置。 该方法包括:接收表示道路虚线的数据,所述数据包括多个线段和道路交通状况; 基于所述多个线段将所述道路虚线扩展为多边形,并且使用所接收的数据为所述多边形创建几何拓扑结构,所述几何拓扑结构包括顶点列表和索引列表; 选择与道路交通状况相对应的纹理坐标; 并使用与道路交通状况对应的所选择的纹理坐标来填充多边形。 在本申请的实施例中提供的道路地图绘制方法和相关联的计算装置中,通过调用纹理来呈现道路交通状况,从而可以利用移动终端的图形处理单元的性能和良好的渲染效果 可以实现,从而清楚地表明道路交通状况。

    • In one aspect, a request to generate an automated tour based on a set of panoramic images is received. Each particular panoramic image is associated with geographic location information and linking information linking the particular panoramic image with one or more other panoramic images in the set. A starting panoramic image and a second panoramic image are determined based at least in part on the starting panoramic image and the linking information associated with the starting and second panoramic images. A first transition between the starting panoramic image and the second panoramic image is also determined based at least in part on the linking information for these panoramic images. Additional panoramic images as well as a second transition for between the additional panoramic images are also determined. The determined panoramic images and transitions are added to the tour according to an order of the tour.
    • 一方面,接收基于一组全景图像生成自动巡视的请求。 每个特定的全景图像与地理位置信息和链接特定全景图像与集合中的一个或多个其他全景图像的链接信息相关联。 至少部分地基于起始全景图像和与起始和第二全景图像相关联的链接信息确定起始全景图像和第二全景图像。 至少部分地基于这些全景图像的链接信息来确定起始全景图像和第二全景图像之间的第一过渡。 还确定附加全景图像以及附加全景图像之间的第二转换。 确定的全景图像和过渡将根据巡视的顺序添加到巡视。
