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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for road map rendering","description":"A road map rendering method and associated computing apparatus are provided.
