Conics and Quadrics
Conics and quadrics are frequently used in various parts of shapes in engineering products. Though they are only one degree higher than lines and planes, their expressive capability is far greater than the latter. Since their geometric and algebraic properties have been fully investigated theoretically, we can use them with confidence. Knowledge of them is necessary not only for their appropriate use, but also for estimating characteristics of the shape around a point on a free- form surface and understanding various techniques of analyzing surface problems.
