1. A method of rendering an item of geometry within a plurality of first regions of a rendering space, each of the first regions being subdivided into a plurality of second regions, the method comprising:
for each first region of the plurality of first regions,
based on a coverage of the item of geometry within the first region, selecting whether to add the item of geometry to a first control list for the first region or to one or more second control lists for a respective one or more second regions of the plurality of second regions; and
rendering the item of geometry using the first control list or the respective one or more second control lists.
