1. An apparatus for use in a graphics system, said apparatus producing output values corresponding to input pixels, each input pixel having n color components, where n is >

  • =1, each output value representing the result of an n-dimensional lookup of said color components, said apparatus comprising;

    a bus which provides said color components;

    a coordinate translation circuit coupled to said bus for receiving said color components, said coordinate translation circuit configured to perform coordinate translation from said color components to corresponding texture coordinates that collectively determine a texture address; and

    a texture map memory coupled to said coordinate translation circuit, said texture map memory having stored therein a lookup table (LUT).
