| Abstract: | The geometric features modification of NURBS curves are discussed in this paper.By means of constrained optimization,this paper uses the LSM(Least Square Method) to modify the geometric features such as tangency and curvature of the selected point on a NURBS curve.This method is very convenient for interactive,and can realize design and various shape modification effects. |
