Abstract
A graphics processing system maintains a fragment tracking record that stores metadata relating to one or more previously received primitives. The metadata can indicate that the one or more previously received primitives are suitably covered by a subsequently received primitive such that one or more fragment processing operations need not be performed in respect of those one or more previously received primitives. The metadata stored for the one or more previously received primitives can then later be queried by one or more later stages of the graphics processing system to determine whether one or more fragments for the one or more previously received primitives can be at least partially discarded or 'killed'.
