I wouldn't call it ham fist It's really no different than mapping an array except the array is is 2D instead of 1D. You supply data in one or more 2D arrays (textures). You then execute a function (fragment shader) which outputs the values for the result referencing the data in the input arrays (textures). The result is written to another 2D array which just happens to be called a texture instead of "2D array"
