An apparatus and method are described for a non-uniform rasterizer. For example, one embodiment of an apparatus comprises: a graphics processor to process graphics data and render images using the graphics data; and a non-uniform rasterizer within the graphics processor to determine different resolutions to be used for different regions of an image, the non-uniform rasterizer to receive a plurality of polygons to be rasterized and to responsively rasterize the polygons in accordance with the different resolutions.

Apparatus and method for non-uniform frame buffer rasterization

In accordance with some embodiments, the knowledge that a capped frame time is used can be exploited to reduce power consumption. Generally a capped frame time is a pre-allocated amount of time to apply power for rendering in graphics processing. Generally the frame time involves the application of power and some down time in which only idle power is applied pending the next frame time. By making better use of that down time, power consumption reductions can be achieved in some embodiments.

Reducing power consumption during graphics rendering

In the cull pipe, positions of the vertices of a triangle have already been computed and these coordinates may be exploited by taking and sorting triangle groups based on these coordinates. As one example, all the triangles in a tile may constitute a group. The triangle groups are sorted into bins. Within each bin the triangles are sorted based on their depths.

Relaxed sorting in a position-only pipeline

Multi-view rasterization may be performed by calculating visibility over a camera line. Edge equations may be evaluated iteratively along a scanline. The edge equations may be evaluated using single instruction multiple data instruction sets.
