ABSTRACT

Given a point and a rational curve in the plane, their bisector curve is rational [Farouki and Johnston 1994a]. However, in general, the bisector of two rational curves in the plane is not rational [Farouki and Johnstone 1994b]. Given a point and a rational space curve, this art icle shows that the bisector surface is a rational ruled surface. Moreover, given two rational space curves, we show that the bisector surface is rational (except for the degenerate case in which the two curves are coplanar).

REVIEW

"Paolo E. Sabella : Reviewer"

A technique is presented for obtaining the parametric representation of a surface, called the bisector surface, defined as the set of points equidistant from two rational space curves. Previous work has shown that, except in special cases, the more...
