What I've been thinking is to check the angles of the normals on the
four points of the polygon. If one angle is bigger or smaller that a
certain given angle, or deviates too much from the average, subdivide
the polygon. Problem will probably be finding the threshold when to
start subdividing / taking more samples. Especialy for more complex
surfaces like sperical harmonics.
