Characterization of the sphere by means of congruent support cones

Let $M$ be a convex body and let $K$ be a closed convex surface $K$ both contained in the Euclidean space ${\mathbb{E}}^3$. What can we say about $M$ if $K$ encloses $M$ and if from all the points in $K$ the body $M$ looks the same? In this work we are going to present a result which claims that if for every two support cones $C_x$, $C_y$ of $M$, with apexes $x,y\in K$, respectively, there exists $\mathrm{\Phi }$ in the semi direct product of the orthogonal group $O(3)$ and ${\mathbb{E}}^3$ such that $$C_y=\mathrm{\Phi }(C_x),$$ and this can be done in a continuous way, then $M$ is a sphere.
