Abstract:
When performing conservative rasterisation in a graphics processing pipeline, modified edge information that accounts for an error in the dimensions of a primitive is determined by a primitive set-up stage. That modified edge information is then used by a rasterisation stage to determine whether the primitive covers one or more sampling points associated with pixels to be displayed. The same modified edge information can also be used to determine if the pixels are fully covered by the primitive irrespective of any rounding effects (errors) in the position of the (vertices of the) primitive.

Claim (Index 11):
A graphics processor comprising:\n primitive set-up circuitry configured to:\n receive information representing vertices defining a primitive to be rendered by the graphics processing pipeline and to determine therefrom edge information representing the position of the edges of the primitive; and \n use the determined edge information to determine, for the primitive, modified edge information representing modified positions for the edge or edges of the primitive; and \n rasterisation circuitry configured to: use the modified edge information for the primitive to determine, for at least one region of a graphics render output being generated, whether the primitive covers the region of the render output by:\n determining using the modified edge information for the primitive whether the primitive covers at least one sampling point of a group of one or more sampling points from a sampling point grid representing the render output being generated that represents the region of the render output.
