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.

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.
