17 class Interpolate from GeomLib
19 ---Purpose: this class is used to construct a BSpline curve by
20 -- interpolation of points at given parameters The
21 -- continuity of the curve is degree - 1 and the
22 -- method used when boundary condition are not given
23 -- is to use odd degrees and null the derivatives on
24 -- both sides from degree -1 down to (degree+1) / 2
25 -- When even degree is given the returned curve is of
26 -- degree - 1 so that the degree of the curve is odd
