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) C = new Geom_BezierCurve (Poles); GeomAdaptor_Curve Curve (C); Real CDeflect = 0.01; //Curvature deflection Real ADeflect = 0.09; //Angular deflection

GCPnts_TangentialDeflection PointsOnCurve; PointsOnCurve.Initialize (Curve, ADeflect, CDeflect);

Real U; gp_Pnt P; for (Integer i=1; i<=PointsOnCurve.NbPoints();i++) { U = PointsOnCurve.Parameter (i); P = PointsOnCurve.Value (i); }
