Detailed Description

This class describes a MultiCurve approximating a Multiline. As a Multiline is a set of n lines, a MultiCurve is a set of n curves. These curves are Bezier curves. A MultiCurve is composed of m MultiPoint. The approximating degree of these n curves is the same for each one.

Example of a MultiCurve composed 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.
