I have drawn a Bezier Curve or BSpline curve.
How can i draw a tangent to Bezier curve or BSpline curve?
For BSpline Curve : I have used method GeomAPI_Interpolate::Load(initialTangent,finalTangent); method but nothing happens.
For Bezier Curve : I have used LProp_CLProps::Tangent(gp_Dir) but I get compiler error as - 'LProp_CLProps' : undeclared identifier
Thanks in advance.
