Conchoid surfaces of quadrics

D. Gruber and M. Peternell


Abstract:

The conchoid surface F"d 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^3 and shows that these surfaces admit real rational parameterizations. We present an algorithm to compute these parameterizations and discuss several configurations of the position of O with respect to F where the computation simplifies significantly.
