Collapse All
Syntax
C++
OdGeCubicSplineCurve3d(const OdGeKnotVector& knots, const OdGePoint3dArray& fitPnts, const OdGeVector3dArray& firstDerivs, bool isPeriodic = false);
Parameters
Parameters 
Description 
const OdGeKnotVector& knots 
[in] Knot vector.  
const OdGePoint3dArray& fitPnts 
[in] An array of 3D fit points.  
const OdGeVector3dArray& 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 objects of the OdGeCubicSplineCurve3d class. Constructs a cubic spline curve based on fit points, knot vectors and first derivatives at the fit points and option that specifies whether cubic spline curve should be closed. 

 

Remarks

Currently not implemented.
