Abstract: This application relates to the field of graphics rendering technologies, and specifically discloses a graphics rendering method and a related apparatus. A central processing unit CPU captures an instruction stream of a graphics processing unit GPU to obtain vertex data required by the GPU for graphics rendering; the CPU performs primitive processing such as coordinate transformation and clipping on the obtained vertex data to obtain vertex data within a field of view of a user; and the CPU sends the vertex data within the field of view of the user to the graphics processing unit GPU, so that the GPU performs graphics rendering processing based on the vertex data processed by the CPU. In technical solutions provided in this application, load of the GPU can be reduced during graphics rendering.

Abstract: An image rendering method and a related device thereof are disclosed. The method includes: performing ray tracing based on rendering information of a reflecting object, and storing an obtained image of a reflection in the reflecting object in a first frame buffer, where the first frame buffer is used for storing an image that does not need to be displayed temporarily; performing rasterization separately based on the rendering information of the reflecting object and rendering information of a reflected object, and storing an obtained image of the reflecting object and an obtained image of the reflected object in a second frame buffer, where the second frame buffer is used for storing an image to be displayed; and obtaining, from the first frame buffer, the image of the reflection in the reflecting object, and storing the image of the reflection in the reflecting object in the second frame buffer.

Abstract: Embodiments of this application disclose a projection data processing method, to reduce a delay in a wireless projection process. In the embodiments of this application, the method includes: A projection transmit end obtains network status information, and determines a target resolution of an image to be projected based on the network status information; and then determines a to-be-synthesized layer based on whether the image is in a full-screen scenario. Therefore, an amount of data to be sent during projection can be reduced, and a projection delay can be reduced. In addition, a projection receive end can perform super-resolution on the image, to avoid image quality damage caused by reducing the amount of data sent by the transmit end. This solution reduces the projection delay and ensures projection image quality to improve user experience.
