                         or affine constraints. In this method, the constraints and the 
                         user editing actions are combined using weighted and constrained 
                         least squares instead of the usual finite element approach. We use 
                         exact integer arithmetic in order to detect and eliminate 
                         redundancies in the set of constraints and to avoid failures due 
                         to rounding. We are using this technique for the user-friendly 
                         editing of C1-continuous deformations of the plane, defined by 
                         splines of degree 5 on an arbitrary triangular mesh.",
