GetSuperNodeExtent Method

In This Topic

Gets the full extent of the TIN based on the super nodes. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public Envelope GetSuperNodeExtent()

Public Function GetSuperNodeExtent() As Envelope

Return Value

An ArcGIS.Core.Geometry.Envelope.

Exceptions

ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Remarks

When a TIN is initially constructed it contains four generated points that reside far outside the declared data extent. These are connected into two triangles and this initial triangulation is what the data is added to. The four generated points are referred to as super nodes. The super node extent is the minimum bounding rectangle that surrounds these points.

Example

Get Super Node Extent

var superNodeExtent = tinDataset.GetSuperNodeExtent();
