Detailed Description

Computes a set of points on a curve from package Adaptor3d such as between two successive points P1(u1)and P2(u2) :

. ||P1P3^P3P2||/||P1P3||*||P3P2||<AngularDeflection

. ||P1P2^P1P3||/||P1P2||<CurvatureDeflection

where P3 is the point of abscissa ((u1+u2)/2), with u1 the abscissa of the point P1 and u2 the abscissa of the point P2.

^ is the cross product of two vectors, and ||P1P2|| the magnitude of the vector P1P2.

The conditions AngularDeflection > gp::Resolution() and CurvatureDeflection > gp::Resolution() must be satisfied at the construction time.

A minimum number of points can be fixed for a linear or circular element. Example:

Handle(Geom_BezierCurve) aCurve = new Geom_BezierCurve (thePoles);
GeomAdaptor_Curve aCurveAdaptor (aCurve);
double aCDeflect  = 0.01; // Curvature deflection
double anADeflect = 0.09; // Angular   deflection
 
GCPnts_TangentialDeflection aPointsOnCurve;
aPointsOnCurve.Initialize (aCurveAdaptor, anADeflect, aCDeflect);
for (int i = 1; i <= aPointsOnCurve.NbPoints(); ++i)
{
  double aU   = aPointsOnCurve.Parameter (i);
  gp_Pnt aPnt = aPointsOnCurve.Value (i);
}
