RENDERING AN IMAGE ON A DISPLAY SCREEN

摘要

Systems and methods for compositing image layers using a GPU shader module. Image layers may be mapped to a destination surface and tiled such that each tile has the same number and kind of mapped image layers. The mapped image layers of a tile may be provided to a shader module, such as a pixel shader, to composite the image layers into display data.

1. A computerized method for rendering an image on a display screen of an electronic display comprising:
receiving, at a processing circuit, a plurality of image layers; mapping the image layers to a destination surface corresponding to pixels of the display screen; determining, by the processing circuit, one or more tiles for the destination surface, wherein each pixel of a respective tile is mapped to a number of image layers, each image layer containing the same kind of image information; utilizing different shader modules configured to receive and merge respective image layers mapped to respective tiles into display data, each different shader module being utilized for tiles associated with a same respective number of image layers that contain the same kind of image information; and providing the display data to the display screen.
