Abstract: A method of rendering, in a rendering space, a scene formed by primitives in a graphics processing system. A geometry processing phase includes the step of storing fragment shading rate data representing a first fragment shading rate value and associating data identifying a primitive with the fragment shading rate data. A rendering phase includes the steps of retrieving the stored fragment shading rate data and associated data identifying the primitive, obtaining an attachment specifying one or more attachment fragment shading rate values for the rendering space; processing the primitive to derive primitive fragments to be shaded; and for each primitive fragment, combining the first fragment shading rate value for the primitive from which the primitive fragment is derived with an attachment fragment shading rate value from the attachment to produce a resolved combined fragment shading rate value for the respective fragment.

Abstract: A method of rendering a scene formed by primitives in a graphics processing system. For a sequence of primitives, a pipeline fragment shading rate value and a primitive fragment shading rate value for a primitive are combined to produce a combined fragment shading rate value for the primitive. Fragment shading rate data representing the combined fragment shading rate value for the primitive is stored and data identifying the primitive is associated with the fragment shading rate data. For a subsequent primitive, it is determined whether or not a combined fragment shading rate value for the subsequent primitive is the same as for the preceding primitive. If it is the same, data identifying the subsequent primitive is associated with the fragment shading rate data that the data identifying the preceding primitive is associated with.

Abstract: A method of rendering, in a rendering space, a scene formed by primitives in a graphics processing system. A rendering phase receives data describing one or more primitives and one or more associated fragment shading rates to be used during rendering. Fragments for the one or more primitives corresponding to sample positions of the one or more primitives within a region of the rendering space are stored in a buffer sampler. The buffer is parsed to produce microtiles, each microtile corresponding to an array of sample positions within the region and containing sampler fragments from the one or more primitives, the microtiles are analysed to identify shader fragment task instances to be shaded, and the shader fragment task instances are arranged into blocks, wherein at least one block of shader fragment task instances comprises shader fragment task instances from more than one microtile. The blocks of shader fragment task instances are shaded.
