摘要：

A simple and fast method is discussed that allows the generation of an offset curve using a set of control knots for a uniform cubic B-spline. As the control knots lie on the curve, it is easier to visualize and modify the curve in the interactive designing stage. An inversion algorithm is applied to find the control vertices which will be used to obtain the B-spline. The offset points of the knots are computed and the corresponding offset B-spline will be generated. Knot addition can also be readily implemented.
