Description

technical field [0001] The invention belongs to the technical field of graphic generation, and relates to a hardware acceleration realization method and circuit for polygon filling. Background technique [0002] Polygon filling is an important research content of computer graphics. Its function is to modify all pixel units in a given polygonal closed area on the display screen to the specified color data. The existing polygon filling algorithms are generally realized by software algorithms, such as seed filling algorithm, scanning line filling algorithm, edge mark filling algorithm and so on. Its feature is that the software calculates all the pixel color data in the polygon area that needs to be filled and writes it into the frame memory. [0003] With the development of technology, the resolution of liquid crystal displays is getting higher and higher, which involves more and more polygon filling requirements, and the content of the screen to be displayed is also becoming...
