B-spline curve extension is an important operation in computer aided design systems. In this paper, we present a new extension algorithm for B-spline curves. The algorithm uses curve unclamping to generate a uniform B-spline curve segment from the original curve and gradually extends the segment to pass through every target point. Algorithms of uni...

... 1,2 A given B-spline curve c(t) usually needs to be smoothly extended to a target point R or a group of target points {R i } while also maintaining its shape invariance. In general, the ideas for implementing B-spline curve extension can be classified into two types: curve unclamping 3,4 and minimal strain energy. 5,6 The curve unclamping method directly constructs a resulting curve that contains all the curve points of c(t) and passes through every target point. ...
