Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2024/073844, filed on Jan. 24, 2024, which claims priority to Chinese Patent Application No. 202310808445.1, filed on Jun. 30, 2023. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD Embodiments of this application relate to the field of image processing technologies, and in particular, to a rendering method, apparatus, and system. BACKGROUND Currently, users can experience high-definition three-dimensional (3D) games by using terminals. To improve reality and image quality of 3D games, developers can design and add a plurality of special effects, for example, light and shadow effects for the 3D games. As a result, a large quantity of GPU computing resources are consumed when game images in the 3D games are rendered. Consequently, phenomena such as frame freezing and frame dropping occur when the 3D games are run and good game experience cannot be ensured. To resolve the frame freezing problem during 3D game running, some game vendors provide a cloud game solution, that is, a cloud server is used to complete game running logic. However, this solution has a high requirement on quality of a network between a terminal and the cloud server. Once a network problem occurs, the 3D game cannot be run normally. SUMMARY Embodiments of this application provide a rendering method, apparatus, and system to implement normal running of an application. To achieve the foregoing objective, the following technical solutions are used in embodiments of this application. According to a first aspect, an embodiment of this application provides a rendering method. The method is applied to a terminal. The method may be performed by the terminal, or may be performed by a component (for example, a chip, a chip system, or a processor of the terminal). The following uses an example in which the method is performed by the terminal for description, a first application is installed on the terminal, and the method includes: a first area in a first image of the first application is rendered, to obtain a first rendering result of the first area. The terminal sends a first rendering request to a server, and obtains a second rendering result from the server. Then, the terminal fuses the first rendering result and the second rendering result to obtain the first image, and displays the first image. The first rendering request is used to request the server to render a second area in the first image, to obtain the second rendering result, and the second area is an area other than the first area in the first image. In this application, in a running process of the first application, the terminal and the server may collaboratively process a rendering task of the first application, to avoid a performance bottleneck caused by independently processing the rendering task by the server, so that normal running of the first application can be ensured as much as possible. In a design of the first aspect, the method may further include: rendering a third area in a second image of the first application, to obtain a third rendering result of the third area;sending a second rendering request to the server, where the second rendering request is used to request the server to render a fourth area in the second image, to obtain a fourth rendering result, and the fourth area is an area other than the third area in the second image; andwhen the fourth rendering result fails to be obtained from the server, displaying the second image based on the third rendering result. In the method, the terminal renders the third area in a game image. In this way, even if quality of a network between the terminal and the server is poor, and the terminal cannot receive the rendering result of the server or cannot receive the rendering result of the server in time, that the terminal generates the game image including the third area (for example, an area in which a character is located) may not be affected. This meets a requirement for real-time generation and display of the game image including the third area, and improves smoothness of the game image. In a design of the first aspect, the method further includes: sending the rendering request to the server when the quality of the network between the terminal and the server is restored to meet a preset condition. In this way, if the quality of the network does not meet the condition, the terminal does not send the rendering request to the server, and the terminal locally performs rendering. Subsequently, when the quality of the network meets the condition, the terminal may deliver a rendering task of a subsequent frame to the server. In a design of the first aspect, the first area is a dynamic image area in the first image, and the second area is a static image area in the first image; or the first area is a low-level high-frequency area in the first i
