IPolycurve3D.Generalize3D Method

Generalizes this polycurve using the Douglas-Peucker algorithm.

[Visual Basic .NET]
Public Sub Generalize3D ( _
    ByVal maxAllowableOffset As Double _
)
[C#]
public void Generalize3D (
    double maxAllowableOffset
);

Description

Generalizes each part of a Polycurve into a generalized collection of Line segments.  Generalize3D performs a Douglas-Peucker Generalization algorithm, extended to operate in 3D space, with a specified maximum offset tolerance, given in 3D, as input. For Line segments, the generalized output is a subset of the original input vertices.  For non-linear segments, the generalized output contains points along all parts of the curve, not necessarily only the vertices.

[C#]

 

 

        public static void Generalize3D()

        {

               const double GeneralizeMaxAllowableOffset = 2.229; 

 

               IGeometry polylineGeometry = GetPolylineGeometry();

               IPolycurve3D polycurve3D = polylineGeometry as IPolycurve3D;

               polycurve3D.Generalize3D(GeneralizeMaxAllowableOffset);


               ITopologicalOperator topologicalOperator = polylineGeometry as ITopologicalOperator;

               topologicalOperator.Simplify();

        }
