Convert_CompPolynomialToPoles Class Reference

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

Standard_EXPORT Convert_CompPolynomialToPoles (const Standard_Integer NumCurves, const Standard_Integer Continuity, const Standard_Integer Dimension, const Standard_Integer MaxDegree, const Handle(TColStd_HArray1OfInteger)&NumCoeffPerCurve, const Handle(TColStd_HArray1OfReal)&Coefficients, const Handle(TColStd_HArray2OfReal)&PolynomialIntervals, const Handle(TColStd_HArray1OfReal)&TrueIntervals)
 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}
