Abstract:
A computer-implemented method for drawing graphical objects within a graphics processing pipeline is disclosed. The method includes determining that a bypass mode for a first primitive is a no-bypass mode. The method further includes rasterizing the first primitive to generate a first set of rasterization results. The method further includes generating a first set of colors for the first set of rasterization results via a pixel shader unit. The method further includes rasterizing a second primitive to generate a second set of rasterization results. The method further includes generating a second set of colors for the second set of rasterization results without the pixel shader unit performing any processing operations on the second set of rasterization results. The method further includes transmitting the first set of pixel colors and the second set of pixel colors to a raster operations (ROP) unit for further processing.
