Support function - Wikipedia

    https://en.wikipedia.org/wiki/Support_function
    The support function is a convex function on . Any non-empty closed convex set A is uniquely determined by h A . Furthermore, the support function, as a function of the set A is compatible with many natural geometric operations, like scaling, translation, rotation and Minkowski addition .

    scheme for convex bodies is the support function representation [3, 13, 29]. It was introduced by Minkowski in 1903, and has been extensively studied by mathematicians thereafter. The representation scheme goes as follows. Let A‰Rd be a convex body (i.e., nonempty compact convex set) in the real Euclidean d-dimensional spaceRd. The support ...
