static

Builds the poles of the 1d bspline that is null on the rigth side of Knots(Index) (on the left if NulOnTheRight is false) and that is like a t*(1-t)(1-t) curve on the left side of Knots(Index) (on the rigth if NulOnTheRight is false). The result curve is C1 with a derivative equal to 1. at first parameter (-1 at last parameter if NulOnTheRight is false). Warning: Mults(Index) must greater or equal to degree-1.
