If the function f takes a long time to compute, it's not always practical to sample it sufficiently finely to generate good-quality plots. Would it be possible to interpolate the data, maybe even in a very simple fashion, to get sufficient resolution images from sparsely sampled (eg 100x100) source data, like most plotting packages do?
