Abstract
In the graphics rendering pipeline, rasterization is the core component that converts the vertex information of primitives into pixel fragments through interpolation scanning, and is an important part of the graphics processing unit (GPU). The rasterization process directly affects the rendering efficiency and rendering quality of the entire graphics processor. Against at the problem of repeated calculation of the same pixel attribute in traditional forward rendering, a deferred shading algorithm is proposed based on the gravity coordinate perspective correction algorithm and the edge function parallel scanning algorithm, reduce computational complexity and reduce the number of pixels traversed. This time, a verification scheme combining functional simulation and FPGA verification was used to write a large number of test cases. Finally, the software and hardware results were compared to complete the board-level verification. After calculation, the average is in each scene graph, the number of pixel attribute calculations is reduced by 168,000, and the performance exceeds 70%.
