This class describes a MultiBSpCurve approximating a Multiline. Just as a Multiline is a set of a given number of lines, a MultiBSpCurve is a set of a specified number of bsplines defined by:
Example of a MultiBSpCurve composed of a specified number of MultiPoints:
P1______P2_____P3______P4________........_____PNbMPoints
Q1______Q2_____Q3______Q4________........_____QNbMPoints . . . . . . R1______R2_____R3______R4________........_____RNbMPoints
Pi, Qi, ..., Ri are points of dimension 2 or 3.
(Pi, Qi, ...Ri), i= 1,...NbPoles are MultiPoints. each MultiPoint has got NbPol Poles. MultiBSpCurves are created by the SplineValue method in the ComputeLine class, and by the Value method in TheVariational class. MultiBSpCurve provides the information required to create the BSpline defined by the approximation.
