1. A map rendering method, performed by a terminal having a processor and memory storing a plurality of computer programs to be executed by the processor, wherein the plurality of computer programs include a three-dimensional display engine, a native map module, and a target map interface, the method comprising:
transmitting, when the three-dimensional display engine receives a mesh update instruction, a block request to the native map module through the three-dimensional display engine, the block request carrying a block identifier corresponding to a target field of view area;
obtaining a block data address based on the block identifier through the native map module, and returning the block data address to the three-dimensional display engine;
obtaining block data in the target field of view area based on the block data address through the three-dimensional display engine;
invoking the target map interface through the native map module, to parse the block data, and generating map mesh data based on data obtained through parsing, the map mesh data comprising road data and building data; and
performing map rendering based on the road data and the building data in the map mesh data.
