1. A method comprising: determining a distance between each of a plurality of texture block texels in a texture block and each of a plurality of points, wherein the plurality of points are selected from at least an edge of the texture block, and wherein the plurality of points comprise radial basis function (RBF) center points; determining a set of texel color values sampled over the texture block; generating a set of approximation coefficients to compress the texture block using the distance between each of the plurality of texture block texels and each of the plurality of points and the set of texel color values sampled over the texture block; and applying texture data to an image using the set of approximation coefficients.
