Rendering method and apparatus, device, computer readable storage medium and product

An electronic device, comprising:

• a processor and a memory, wherein:
• the memory stores therein computer executable instructions;
• the computer executable instructions stored in the memory, when executed by the processor, cause the processor to:
• obtain a first context associated with a plurality of preset windows to be rendered, wherein the first context is used for managing a rendering resource and an interface status associated with respective preset windows;
• perform, based on the first context, off-screen content rendering on an extended surface associated with each preset window, to obtain a rendered content corresponding to each preset window;
• and
• render, based on a second context associated with each preset window, the rendered content corresponding to the preset window onto the preset window, the second context being used for managing the extended surface corresponding to each preset window, and the first context sharing a rendering resource with the second context associated with the preset window.

A non-transitory computer readable storage medium, wherein the computer readable storage medium stores therein computer executable instructions that, when executed by a processor, cause a computer to:

• obtain a first context associated with a plurality of preset windows to be rendered, wherein the first context is used for managing a rendering resource and an interface status associated with respective preset windows;
• perform, based on the first context, off-screen content rendering on an extended surface associated with each preset window, to obtain a rendered content corresponding to each preset window;
• and
• render, based on a second context associated with each preset window, the rendered content corresponding to the preset window onto the preset window, the second context being used for managing the extended surface corresponding to each preset window, and the first context sharing a rendering resource with the second context associated with the preset window.
