Retrieves the triangles in the TIN that satisfy the criteria set in the . If no filter is set, all triangles will be retrieved. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public TinTriangleCursor SearchTriangles( 
   TinTriangleFilter filter
)

Public Function SearchTriangles( _
   ByVal filter As TinTriangleFilter _
) As TinTriangleCursor

Parameters

filter: Filter by parameters. See TinTriangleFilter. If null, then all triangles will be retrieved.

Return Value

A TinTriangleCursor.

Exceptions

Example

Search for TIN Triangles

// search all triangles
using (ArcGIS.Core.Data.Analyst3D.TinTriangleCursor triangleCursor = tinDataset.SearchTriangles(null))
{
  while (triangleCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinTriangle triangle = triangleCursor.Current)
    {

    }
  }
}

// search within an extent
ArcGIS.Core.Data.Analyst3D.TinTriangleFilter triangleFilter = new ArcGIS.Core.Data.Analyst3D.TinTriangleFilter();
triangleFilter.FilterEnvelope = envelope;
using (ArcGIS.Core.Data.Analyst3D.TinTriangleCursor triangleCursor = tinDataset.SearchTriangles(triangleFilter))
{
  while (triangleCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinTriangle triangle = triangleCursor.Current)
    {

    }
  }
}

// search all "inside" triangles
triangleFilter = new ArcGIS.Core.Data.Analyst3D.TinTriangleFilter();
triangleFilter.FilterType = ArcGIS.Core.Data.Analyst3D.TinFilterType.InsideDataArea;
using (ArcGIS.Core.Data.Analyst3D.TinTriangleCursor triangleCursor = tinDataset.SearchTriangles(triangleFilter))
{
  while (triangleCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.TinTriangle triangle = triangleCursor.Current)
    {

    }
  }
}
