1. A method for assigning coefficients to a texel of a parametric texture map (PTM) texture, comprising: (a) generating a random PTM matrix of a desired size, said random PTM matrix comprising texels possessing random valued coefficients; (b) selecting a texel from said random PTM matrix; (c) determining a first neighborhood of said texel from said random PTM matrix; (d) comparing said first neighborhood to neighborhoods of a sample PTM textire to determine an optimal texel of said sample PTM texture; and (e) assignindg PTM coefficients of said optimal texel to said texel from said random PTM matrix.
