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

Visual Basic (Declaration)
C#

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

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

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
  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);
}
