Quadric surface free pdf notes download, Computer Aided Design pdf notes
In computer graphics all surfaces can be represented as in their quadratic form with the help of mathematical equations.these are described with second degree equations.
Quadric surfaces: The zero set of a polynomial P(X) = P (X1. . . Xn) ∈Q[X1, . . . ,Xn] is a hyper surface in n-dimensional affine space (either real or complex). When P(X) is homogeneous, it is called a form and defines a hypersurface in (n − 1)-dimensional projective space. When deg(P) = 2, the polynomial is quadratic and the corresponding hypersurface is quadric. We shall reserve the term “surface” for 3-dimensional affine or projective hypersurface.
