Detailed Description

An algorithm for computing local properties of a curve.
These properties include:

• the maximum and minimum curvatures
  
• the inflection points.
  A CurAndInf2d object provides the framework for:
  
• defining the curve to be analyzed
  
• implementing the computation algorithms
  
• consulting the results.
  

Constructor & Destructor Documentation

Geom2dLProp_CurAndInf2d::Geom2dLProp_CurAndInf2d

(

)

 Initializes the framework. <br>

Note: The curve on which the local properties are
computed is defined using one of the following
functions: Perform, PerformCurExt or PerformInf.

Member Function Documentation

Standard_Boolean Geom2dLProp_CurAndInf2d::IsDone

(

)

const

True if the solutions are found.

void Geom2dLProp_CurAndInf2d::Perform

(

const Handle< Geom2d_Curve > &

C

)

For the curve C, Computes both the <br>

inflection points and the maximum and minimum curvatures.

void Geom2dLProp_CurAndInf2d::PerformCurExt

(

const Handle< Geom2d_Curve > &

C

)

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

void Geom2dLProp_CurAndInf2d::PerformInf

(

const Handle< Geom2d_Curve > &

C

)

 For the curve C, Computes the inflections. <br>

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.
