Short Communication A note on approximation of discrete data by G1 arc splines
Computer-Aided Design 31 (1999) 911-915，-0001，（）：
Meek and Walton discussed the approximation of discrete data by G1 arc splines in 1992. For a biarc from the start point A to the end point B, they assumed that the sum of two counterclockwise angles of the two arcs was equal to the sum of the counterclockwise angle from the start tangent vector to the vector B-A and that from the vector B-A to the terminal tangent vector. In this note, we show that the relation can be relaxed by the addition or subtraction of 2π.
