In This Topic

Syntax

public int GetOutsideTriangleCount()

Public Function GetOutsideTriangleCount() As Integer

Return Value

The number of outside triangles in this TIN.

Exceptions

Exception	Description
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.

Remarks

TIN elements can exist "inside" or "outside" the TIN's data area. When TINs are initially built the only elements that are "outside" are the four super nodes and their incident edges and triangles. If clip or erase polygons are added to a TIN, they further modify what is considered to be "inside" or "outside".

Example

Element Counts

var nodeCount = tinDataset.GetNodeCount();
var outsideNodeCount = tinDataset.GetOutsideNodeCount();
var edgeCount = tinDataset.GetEdgeCount();
var outsideEdgecount = tinDataset.GetOutsideEdgeCount();
var triCount = tinDataset.GetTriangleCount();
var outsideTriCount = tinDataset.GetOutsideTriangleCount();

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.2 or higher.
