US 12,008,675 B2 · Method and apparatus for isolating 3D draw calls for selective upscaling

Abstract

A system and a method are disclosed for separating 3D content from 2D UI content for selectively upscaling 3D draw calls. A controller, coupled to a graphics pipeline, determines whether an application supports upscaling and, if so, creates a full-resolution framebuffer for rendering 2D drawcalls bound to the graphics pipeline and a reduced-resolution framebuffer for rendering 3D drawcalls bound to the graphics pipeline. A drawcall is then determined to be a 2D or a 3D drawcall. The controller stores the drawcall in the full-resolution framebuffer if the draw call is a 2D drawcall and stores the drawcall in the reduced-resolution framebuffer if the draw call is a 3D drawcall. The draw stored in the reduced-resolution framebuffer is upscaled to be a full-resolution drawcall, and the 2D draw in the full-resolution framebuffer and the upscaled 3D draw are combined to form a final output.

Dependent claims

A method to render two-dimensional (2D) content and three-dimensional (3D) content of an application by a graphics processing unit (GPU), the method comprising:

creating, by the GPU, a full-resolution frame buffer for rendering 2D draw calls and a reduced-resolution frame buffer for rendering 3D draw calls based on upscaling being supported;
receiving, by the GPU, a draw call;
determining, by the GPU, that the draw call comprises both a 2D draw call and a 3D draw call based on determining rendering quadrants of the draw call, and, in response, separating the 2D draw call from the 3D draw call by:
storing the 2D draw call in the full-resolution frame buffer, and
storing the 3D draw call in the reduced-resolution frame buffer;
upscaling, by the GPU, the draw call stored in the reduced-resolution frame buffer from a reduced-resolution to a full-resolution draw call;
and
combining, by the GPU, the 2D draw call in the full-resolution frame buffer and the 3D draw call upscaled to the full-resolution draw call to form a final output.
