In PG(3,p^h), ovoids and cones projecting an oval from a point are characterized as three character sets with respect to lines and planes, respectively.
In PG(3,q), q=p^h a prime power and h having no odd factor, any (q^2+1)-set of class [0,m,n]_1 is an ovoid and any (q^2+q+1)-set of class [1,m,n]_2 containing at least two lines is either a plane or a cone projecting an oval from a point
