Abstract: The present disclosure provides a method and apparatus for processing three dimensional graphic data, a device, a storage medium and a product, relating to a field of artificial intelligence, in particular to a field of autonomous driving. The specific implementation is: receiving a data compression request for a target graphic element in a three dimensional electronic map, and obtaining at least one vertex data corresponding to the target graphic element; extracting a global coordinate matrix with a shared attribute in the at least one vertex data; extracting local coordinate data with a private attribute respectively corresponding to the at least one vertex data; and sending, in response to a graphic drawing request for the target graphic element, the global coordinate matrix and the local coordinate data respectively corresponding to the at least one vertex data to a graphic display device.
