It is used in the package -- AppParCurves. -- The points of the same range for the approximation are -- organised in MultiPointConstraints. These MultiPointConstraints -- -- are organized in a MultiLine. -- The corresponding result of a MultiLine approximation is -- a MultiCurve (set of Bezier curves) which has the same -- structure as a MultiLine: The MultiCurve is a set of -- MultiPoint. -- A point of a MultiLine can have many significations: the approximation curve -- can go through this point or not, can have a given tangency, or can -- have a given curvature. -- Note: a CurvaturePoint is also a PassPoint and a TangencyPoint. -- A TangencyPoint is also a PassPoint. uses AppParCurves, Approx, gp, TColgp, TCollection, Standard, MMgt, math, FEmTool, TColStd, GeomAbs, PLib is class MultiPointConstraint; class MultiLine; class MyLineTool; deferred class SmoothCriterion; class LinearCriteria; class Variational; --- Classes instanciees: class TheLeastSquares instantiates LeastSquare from AppParCurves (MultiLine from AppDef, MyLineTool from AppDef); class TheResol instantiates ResolConstraint from AppParCurves (MultiLine from AppDef, MyLineTool from AppDef); class TheFunction instantiates Function from AppParCurves (MultiLine from AppDef, MyLineTool from AppDef, TheLeastSquares from AppDef, TheResol from AppDef); class TheGradient instantiates Gradient from AppParCurves (MultiLine from AppDef, MyLineTool from AppDef); class Compute instantiates ComputeLine from Approx (MultiLine from AppDef, MyLineTool from AppDef); class BSplineCompute instantiates BSplComputeLine from Approx (MultiLine from AppDef, MyLineTool from AppDef); class Array1OfMultiPointConstraint instantiates Array1 from TCollection (MultiPointConstraint); class HArray1OfMultiPointConstraint instantiates HArray1 from TCollection( MultiPointConstraint,Array1OfMultiPointConstraint); end AppDef;
