Abstract: In order to solve the problem of B-spline curve modeling based on physically deforming with geometry constraints,a method of freedom degree transformation is presented.For certain geometry constraints,by transforming the constrained degrees of freedom,the solution of the reduced unconstrained degrees of freedom finite element is obtained.Examples are presented to show the efficiency of this method.

Key words: deformable curve； geometry constraint； B-spline； finite element；
