摘要

The monotone curvature condition for rational quadratic B-spline curves is studied by using Bernstein base transformation. At first, we present the necessary and sufficient conditions of monotone curvature for the uniform rational quadratic B-spline segment. Then, we give the sufficient condition of monotone curvature for the nonuniform rational quadratic B-spline segment. At last, we obtain the condition of monotone curvature for general rational quadratic B-spline curves with any number of control points.
