Perturbation of Quadrics
The aim of this paper is to study what happens when a slight perturbation a ects the coe cients of a quadratic equation de ning a variety a quadric in R Structurally stable quadrics are those a small perturbation on the coe cients of the equation de ning them does not give rise to a di erent in some sense set of points In particular we characterize structurally stable quadrics and give the bifu...
متن کاملConchoid surfaces of quadrics
The conchoid surface Fd of a surface F with respect to a fixed reference point O is a surface obtained by increasing the distance function with respect to O by a constant d. This contribution studies conchoid surfaces of quadrics in Euclidean R and shows that these surfaces admit real rational parameterizations. We present an algorithm to compute these parameterizations and discuss several conf...
متن کاملBirational geometry of quadrics
A central method in the theory of quadratic forms is the study of function fields of projective quadrics. In particular, it is important to ask when there is a rational map from one quadric over a field to another. This suggests the problem of determining when two quadrics are birational, which turns out to be much harder. The answer is known for quadratic forms of dimension at most 7 (thus for...
متن کاملConvex quadrics
We describe convex quadric hypersurfaces in Rn and characterize them as convex hypersurfaces with quadric sections by a continuous family of hyperplanes.
متن کاملDirect Visualization of Quadrics
Today, most of the powerful graphic systems are based on 3D-triangle display methods. However, this approach generates well-known problems, like the low quality of contours and shading, and the necessity to have large amounts of primitives to display complex scenes. A way to solve these problems is to use higher level primitives, among which a very interesting one is the quadric surface. We stu...
