Method, device and computer storage medium for improving graphics rendering efficiency

Abstract

The embodiment of the invention discloses a method and device for improving graphic rendering efficiency and a computer storage medium. The device comprises a clipping test unit, a depth template testunit, a color mixing unit and a color jittering unit, wherein the clipping test unit is configured to respectively transmit fragment data subjected to clipping test into the depth template test unitand the color mixing unit; the depth template test unit is configured to test the visibility of the fragment data currently transmitted by the clipping test unit and generate a first test result; thecolor mixing unit is configured to perform color mixing on the fragment data currently transmitted by the clipping test unit and transmit the fragment data after color mixing to the color jittering unit, and monitor a first test result in the color mixing process; and, if the first test result is that the test is not passed, color mixing is stopped and the next transmitted fragment data of the clipping test unit is read for color mixing.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of graphics processing units (GPUs), and in particular, to a method, a device, and a computer storage medium for improving graphics rendering efficiency. Background technique [0002] For the current conventional GPU, the graphics rendering pipeline will perform a series of serial operations for each fragment after the fragment shading is completed and before the frame buffer is finally updated, such as tailoring test, depth mask test, and transparency in turn (Alpha) test, etc., and when the clip passes the above test, the color mixing operation will be performed, and the color dithering operation may be performed even after the color mixing operation. The above serial operations process the fragments in sequence, which will cause the graphics rendering pipeline to become longer, and when complex calculations are required, the pipeline will be blocked, which will reduce the efficiency o...

Problems solved by technology

The above serial operations process the fragments sequentially, which will cause the graphics rendering pipeline to become longer. When complex calculations are required, the pipeline will be blocked, which will reduce the efficiency of GPU processing.
