Detailed Description

This class defines an algorithm to create a set of points (with a given chordal deviation) at the positions of constant deflection of a given parametrized curve or a trimmed circle. The continuity of the curve must be at least C2.

the usage of the is the following.

class myUniformDFeflection instantiates UniformDeflection(Curve, Tool);

Curve C; // Curve inherits from Curve or Curve2d from Adaptor2d myUniformDeflection Iter1; DefPntOfmyUniformDeflection P;

for(Iter1.Initialize(C, Deflection, EPSILON, True); Iter1.More(); Iter1.Next()) { P = Iter1.Value(); ... make something with P } if(!Iter1.IsAllDone()) { ... something wrong happened }
