Syntax
C++
OdGeCubicSplineCurve2d(const OdGeKnotVector& knots, const OdGePoint2dArray& fitPnts, const OdGeVector2dArray& firstDerivs, bool isPeriodic = false);
Parameters
Parameters 
Description 
const OdGeKnotVector& knots 
[in] Knot vector.  
const OdGePoint2dArray& fitPnts 
[in] An array of 2D fit points.  
const OdGeVector2dArray& firstDerivs 
[in] Array of first derivatives at the fit points.  
bool isPeriodic = false 
[in] True if the cubic spline curve should be periodic (closed). 
Description

Constructor for the OdGeCubicSplineCurve2d class. Constructs a cubic spline curve from the passed fit points, knots vector, array of first derivatives at the fit points and option that cubic spline curve should be closed. Currently not implemented.
