Builds a B-Spline by a lists of Poles, Mults, Knots.
arguments: poles (sequence of Base.Vector), [mults , knots, periodic, degree, weights (sequence of Base.Vector), CheckRational]
arguments: poles (sequence of Base.Vector), [mults , knots, periodic, degree, weights (sequence of float), CheckRational]
Examples:
from FreeCAD import Base
import Part
V=Base.Vector
poles=[V(-10,-10),V(10,-10),V(10,10),V(-10,10)]
# non-periodic spline
n=Part.BSplineCurve()
n.buildFromPolesMultsKnots(poles,(3,1,3),(0,0.5,1),False,2)
Part.show(n.toShape())
# periodic spline
p=Part.BSplineCurve()
p.buildFromPolesMultsKnots(poles,(1,1,1,1,1),(0,0.25,0.5,0.75,1),True,2)
Part.show(p.toShape())
# periodic and rational spline
r=Part.BSplineCurve()
r.buildFromPolesMultsKnots(poles,(1,1,1,1,1),(0,0.25,0.5,0.75,1),True,2,(1,0.8,0.7,0.2))
