IPolycurve3D.Weed3D Method

Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.

[Visual Basic .NET]
Public Sub Weed3D ( _
    ByVal maxAllowableOffsetFactor As Double _
)
[C#]
public void Weed3D (
    double maxAllowableOffsetFactor
);
[C++]
HRESULT Weed3D(
  double maxAllowableOffsetFactor
);
[C++]
Parameters
maxAllowableOffsetFactor 

maxAllowableOffsetFactor is a parameter of type double

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Weed generalizes each part of a Polycurve into a generalized collection of z aware Line segments.  Weed performs a Douglas-Poiker Generalization algorithm, extended to operate in 3D space, with a specified multiple of the internal tolerance given 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 Weed3D()

        {

               const double WeedMaxAllowableOffset = 64129865400; 

 

               IGeometry polylineGeometry = GetPolylineGeometry();

               IPolycurve3D polycurve3D = polylineGeometry as IPolycurve3D;

               polycurve3D.Weed3D(WeedMaxAllowableOffset);


               ITopologicalOperator topologicalOperator = polylineGeometry as ITopologicalOperator;

               topologicalOperator.Simplify();

        }
