Abstract: The value of the time average Poynting vector P_{ave} in resolving some direct
and inverse electromagnetic problems at
optical frequencies is claimed. The noticed analogy between
P_{ave} and electrostatic field on the surface of a
rough object, assumed as a perfect conductor, is fruitfully exploited and the
usual Lambert law governing diffuse scattering is re-examined. The given
theoretical support is especially recommended to unambiguously resolve, in
computer graphics, the direct object-rendering problem and to deal
appropriately, in computer vision, with the inverse object-recovering
problem.
