8.1.3 Fog (MGL)

MGL command: fog val [dz=0.25]

Command imitate a fog in the plot. Fog start from relative distance dz from view point and its density growths exponentially in depth. So that the fog influence is determined by law ~1-exp(-d*z). Here z is normalized to 1 depth of the plot. If value val=0 then the fog is absent. See section Surface in fog sample, for sample code and picture.
