1. A system for texturing surfaces displayed as computer graphics images of modeled objects having defined surfaces on a display of pixels having pixel addresses comprising:

  • (a) block storage means for storing texture patterns composed of texels having texel addresses, said texture patterns being stored in blocks of texels with each block having a pre-defined block address;

    (b) processor means for computing the texel addresses associated with said pixel addresses and for processing texel data into pixel data;

    (c) address converter means coupled to said processor means for converting texel addresses into block addresses;

    (d) sort means coupled to said address converter means for sorting block addresses received from said address converter means whereby multiple address references to the same block are consolidated to a single address referencing the block to provide consolidated block address information wherein each of the consolidated block addresses references different blocks of texels; and

    (e) retrieval means coupled to said sort means and to said block storage means for retrieving texture pattern blocks based on said consolidated block address information from said block storage means and for supplying said retrieved texture pattern blocks to said processor means.
