SetToConstrainedDelaunay Method

In This Topic

Sets the triangulation method to constrained Delaunay from this point forward. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void SetToConstrainedDelaunay()

Public Sub SetToConstrainedDelaunay()

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method must be called on the MCT. Use QueuedTask.Run.
ArcGIS.Core.Data.Exceptions.TinException	The editor is not in edit mode.

Remarks

Once this has been set, breaklines will no longer be densified with Steiner points in order to ensure the triangulation conforms to Delaunay criteria. The benefit of having it constrained is you get a best fit match between input and output surface without the need to add densification points. The drawback is the natural neighbors interpolator can't be used on a constrained TIN.

Once a TIN has been placed in this mode it cannot be changed back by any means other than not saving the edit session used to call this method.

Example

Set to constrained Delaunay

// Set the triangulation method to constrained Delaunay from this point forward
tinEditor.SetToConstrainedDelaunay();

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.5 or higher.
