A spatiotemporal-frequency analysis helps one to understand this as well, because a continuous and a sampled stimulus share a great deal of spatiotemporal energy, even if they do not share it all. We can expect the two stimuli to look similar insofar as there are visual mechanisms that respond to the shared energy.
