Extending the well-known characteristic property of solid ellipsoids as convex bodies with hyperplanar shadow-boundaries, we describe all n-dimensional closed convex sets in Rn whose shadow-boundaries satisfy certain conditions of hyperplanarity.
Keywords: Convex, body, ellipsoid, hypersurface, sharp shadow-boundary, solid, quadric.
