C](2)) > 2, A is not the complete intersection of 2 quadrics and hence deg(A) = 3.
It includes natural quadrics (cylinder, cone and sphere), revolute quadrics, tori, pipes and Dupin cyclide.
In fact, the intersection of two quadrics is a question that has been studied extensively in various contexts because of its usefulness in computer aided design, solid modeling, and design of mechanical parts (see [1] and the references therein for detailed discussions of the relevant issues).
