Rendering method and apparatus

A graphics rendering apparatus, wherein the graphics rendering apparatus comprises a memory and a processor, the memory is configured to store computer-readable instructions, and the processor executes the instructions to:

• before a network jitter occurs on a network, receive, by the server, operation instructions from an electronic device through the network, generate a plurality of first rendering instruction streams based on the operation instructions, and send the plurality of first rendering instruction streams to the electronic device;
• and generate and store, by the server, one or more first rendering contexts for one or more first rendering instruction streams in the plurality of first rendering instruction streams, wherein the one or more first rendering contexts one-to-one correspond to the one or more first rendering instruction streams, and each of the one or more first rendering contexts comprises a corresponding first rendering instruction stream or information used for restoring the corresponding first rendering instruction stream;
• when the network jitter occurs, continue, by the server, to generate a second rendering instruction stream based on received operation instructions, and generate and store a second rendering context based on the second rendering instruction stream, wherein the second rendering context comprises the second rendering instruction stream or information used for restoring the second rendering instruction stream, and the second rendering instruction stream is a rendering instruction stream most recently generated before recovery from the network jitter;
• and
• after the recovery from the network jitter, send, by the server, a set of rendering context differences to the electronic device, wherein the set of rendering context differences comprises one or more rendering context differences, wherein each of the one or more rendering context differences is a difference between the second rendering context and one of the first rendering contexts, and the electronic device uses the set of rendering context differences to obtain the second rendering instruction stream.
