By domain-modeling techniques, we mean those operations on datasets that modify the sampling domain representation (e.g., the grid) but not the sampled data. As we shall see, domain-modeling techniques can modify the actual values of the data attributes stored on a given grid, for example in the case of resampling the data on a different grid. However, this modification does not change the reconstructed function, so the meaning of the data attributes stays the same, even though their internal representation may change.
