GetPointsBetweenZs Method

In This Topic

Gets the set of coordinates for this TIN triangle that falls within the specified Z values. Use these coordinates to build a 3D polygonal definition for the area of the triangle that falls within the specified Z values. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public IReadOnlyList<Coordinate3D> GetPointsBetweenZs( 
   double minZ,
   double maxZ
)

Public Function GetPointsBetweenZs( _
   ByVal minZ As Double, _
   ByVal maxZ As Double _
) As IReadOnlyList(Of Coordinate3D)

Parameters

minZ: The minimum Z value.
maxZ: The maximum Z value.

Return Value

An IReadOnlyList of ArcGIS.Core.Geometry.Coordinate3D.

Exceptions

Exception	Description
System.ArgumentException	minZ and maxZ cannot be NaN values.
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Example

TIN Triangles

// nodes, edges of the triangle
var triNnodes = triangle.Nodes;
var triEdges = triangle.Edges;

// triangle geometry
var polygon = triangle.ToPolygon();
// triangle length
var triLength = triangle.Length;
// triangle area 
var triArea = triangle.Area;
// is the triangle "inside"
var isInsideTriangle = triangle.IsInsideDataArea;

// triangle aspect and slope  (radians)
var aspect = triangle.Aspect;
var slope = triangle.Slope;

// get centroid
var centroid = triangle.GetCentroid();

// get normal
var normal = triangle.GetNormal();

// get adjacent triangles
var adjTriangles = triangle.GetAdjacentTriangles();

// get area of triangle that falls between the z values
double minZ = 1.0;
double maxZ = 3.0;
IReadOnlyList<Coordinate3D> coords = triangle.GetPointsBetweenZs(minZ, maxZ);
