This is not explicitly documented (or at least I could not find any mention of it), but from looking at the plots it seems to me that with ListDensityPlot (and related functions), an InterpolationOrder higher than 1 only work with data that lies on a regular grid. So for example the following data cannot be plotted with InterpolationOrder higher than 1: data = {#1, #2, Sin[#1] Sin[#2]} & @@@ RandomReal[2 Pi, {100, 2}]; Is this correct?
