Convert a serie of Polynomial N-Dimensional Curves that are have continuity CM to an N-Dimensional Bspline Curve that has continuity CM. (to convert an function (curve) polynomial by span in a BSpline) This class uses the following arguments : NumCurves : the number of Polynomial Curves Continuity: the requested continuity for the n-dimensional Spline Dimension : the dimension of the Spline MaxDegree : maximum allowed degree for each composite polynomial segment. NumCoeffPerCurve : the number of coefficient per segments = degree - 1 Coefficients : the coefficients organized in the following way [1..<myNumPolynomials>][1..myMaxDegree +1][1..myDimension] that is : index [n,d,i] is at slot (n-1) * (myMaxDegree + 1) * myDimension + (d-1) * myDimension + i PolynomialIntervals : nth polynomial represents a polynomial between myPolynomialIntervals->Value(n,0) and myPolynomialIntervals->Value(n,1) TrueIntervals : the nth polynomial has to be mapped linearly to be defined on the following interval : myTrueIntervals->Value(n) and myTrueIntervals->Value(n+1) so that it represent adequatly the function with the required continuity.

Warning! Continuity can be at MOST the maximum degree of the polynomial functions TrueIntervals : this is the true parameterisation for the composite curve that is : the curve has myContinuity if the nth curve is parameterized between myTrueIntervals(n) and myTrueIntervals(n+1)
Coefficients have to be the implicit "c form": Coefficients[Numcurves][MaxDegree+1][Dimension]
Warning! The NumberOfCoefficient of an polynome is his degree + 1 Example: To convert the linear function f(x) = 2*x + 1 on the domaine [2,5] to BSpline with the bound [-1,1]. Arguments are : NumCurves = 1; Continuity = 1; Dimension = 1; MaxDegree = 1; NumCoeffPerCurve [1] = {2}; Coefficients[2] = {1, 2}; PolynomialIntervals[1,2] = {{2,5}} TrueIntervals[2] = {-1, 1}
