1. A graphics processor for processing vertices of a polygon, the graphics processor comprising:

  • an input for receiving an instruction for processing a given vertex;

    memory for storing a first lookup table and a second lookup table, each of the first and second lookup tables corresponding to a selected function and containing table output as a function of an input value, the input value corresponding to data relating to the given vertex; and

    an interpolation engine, responsive to receipt of the instruction from the input, selects one of the lookup tables, determines table output from the one of the lookup tables, and produces an output value based upon the table output and data relating to the given vertex.
