Abstract

In graphics processing data is received representing one or more vertices for a scene in a virtual space. A projection of the vertices onto a screen space of a display device is performed. The projection approximates a projection of the vertices onto a curved viewport. Primitive assembly is performed on the vertices to generate a one or more primitives in screen space from the projection of the vertices onto the screen space. Scan conversion is performed on the one or more primitives to determine which pixel or pixels of the plurality of pixels are part of corresponding primitives of the one or more primitives. A finished frame is then generated by performing pixel processing to assign pixel values to the pixel or pixels that are part of the corresponding primitives. In some implementations, the finished frame can be stored in the memory or displayed on the display device.
