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.

Initializes the framework. 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

IsDone()

bool GeomLProp_CurAndInf2d::IsDone

(

)

const

True if the solutions are found.

Perform()

void GeomLProp_CurAndInf2d::Perform

(

const occ::handle< Geom2d_Curve > &

C

)

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

PerformCurExt()

void GeomLProp_CurAndInf2d::PerformCurExt

(

const occ::handle< Geom2d_Curve > &

C

)

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

PerformInf()

void GeomLProp_CurAndInf2d::PerformInf

(

const occ::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.
