Claim 10:
11. A graphics processing system configured to render a scene formed by primitives, wherein the graphics processing system comprises geometry processing logic configured to:
combine a pipeline fragment shading rate value and a primitive fragment shading rate value for a primitive in a sequence of primitives to produce a combined fragment shading rate value for the primitive;
store fragment shading rate data representing the combined fragment shading rate value for the primitive and associating vertex data of the primitive with the fragment shading rate data;
determine, for a subsequent primitive, if a combined fragment shading rate value for the subsequent primitive is the same as for the preceding primitive, and
if the combined fragment shading rate value for the subsequent primitive is the same as for the preceding primitive, associate vertex data of the subsequent primitive with the fragment shading rate data that the vertex data of the preceding primitive is associated with, and repeat the determining step for a next subsequent primitive, if there is one; and
if the combined fragment shading rate value for the subsequent primitive is not the same as for the preceding primitive, store further fragment shading rate data representing the combined fragment shading rate value for the subsequent primitive and associate vertex data of the subsequent primitive with the further fragment shading rate data; and repeat the determining step for a next subsequent primitive, if there is one.
