1. A method of operating a graphics processor to process sets of geometry for an application in order to generate a render output for the application, the method comprising:
when processing plural sets of geometry for the render output, wherein each set of geometry is associated with respective lower level geometry data that is to be used when rendering the set of geometry, the associated lower level geometry data for a set of geometry including vertex data representing a set of vertices for the geometry in the set of geometry, and wherein each set of geometry is further associated with a higher level representation of the position of the set of geometry, the higher level representation of the position of the set of geometry being separate and in addition to the associated lower level geometry data for the set of geometry and being obtainable by the graphics processor independently of the associated lower level geometry data:
for each set of geometry to be processed:
the graphics processor obtaining the higher level representation of the position of the set of geometry; and
the graphics processor determining, using the higher level representation of the position of the set of geometry, which region or regions of a plurality of regions into which the render output has been divided, the set of geometry should be processed for, wherein each region comprises a respective area of the render output;
the graphics processor thereby generating one or more lists indicating which sets of geometry should be processed for which regions of the render output;
the method further comprising:
after the one or more lists indicating which sets of geometry should be processed for which regions of the render output have been generated:
for a region of the render output to be rendered:
determining using the respective list(s) for the region of the render output which sets of geometry should be processed for the region of the render output;
obtaining the associated lower level geometry data for each of the sets of geometry that are indicated to be processed for the region, the obtained lower level geometry data including the vertex data representing the vertices for the geometry in the sets of geometry that are indicated to be processed for the region; and
processing the obtained lower level geometry data to generate a render output.
