    review text
    The author considers elements of the Euclidean differential geometry of shadow contours on a torus by means of an auxiliary ruled surface which contains information on first order derivatives, thereby reducing further differentiations to `elementary' operations, i.e., the construction of tangent planes.NEWLINENEWLINEFor the entire collection see [Zbl 0959.00032].
