◆ Geom2dLProp_CurAndInf2d()

Member Function Documentation

◆ IsDone()

Standard_Boolean Geom2dLProp_CurAndInf2d::IsDone ( ) const

True if the solutions are found.

◆ Perform()

void Geom2dLProp_CurAndInf2d::Perform ( const Handle< Geom2d_Curve > &  C)

For the curve C, Computes both the inflection points and the maximum and minimum curvatures.

◆ PerformCurExt()

void Geom2dLProp_CurAndInf2d::PerformCurExt ( const Handle< Geom2d_Curve > &  C)

For the curve C, Computes the locals extremas of curvature.

◆ PerformInf()

void Geom2dLProp_CurAndInf2d::PerformInf ( const Handle< Geom2d_Curve > &  C)

For the curve C, Computes the inflections. After computation, the following functions can be used:

  • IsDone to check if the computation was successful
  • NbPoints to obtain the number of computed particular points
  • Parameter to obtain the parameter on the curve for each particular point
  • Type to check if the point is an inflection point or an extremum of curvature of the curve C. Warning These functions can be used to analyze a series of curves, however it is necessary to clear the table of results between each computation.
