Abstract: The disclosure provides image rendering methods and apparatuses. One example method includes that a foreground image is first rendered, and then a panoramic image used as a background is rendered. A pixel corresponding to the foreground image has a corresponding depth value. When the panoramic image is rendered, content corresponding to the panoramic image may be rendered at a pixel corresponding to a depth standard value based on a depth value of a pixel on a canvas. The depth reference value is a depth value of a pixel other than the pixel corresponding to the foreground image.

Abstract: Embodiments of this application provide a rendering method and apparatus, and the like. The method includes: A processor (which is usually a CPU) modifies a rendering instruction based on a relationship between a first frame buffer and a second frame buffer, so that a GPU renders a rendering job corresponding to the first frame buffer to the second frame buffer based on a new rendering instruction. In this application, render passes of one or more frame buffers are redirected to another frame buffer. In this way, memory occupation in a rendering process of an application program is effectively reduced, bandwidth of the GPU is reduced, and power consumption can be reduced.
