MultipatchBuilderEx Constructor(MultipatchConstructType,MapPoint,Double,Double,SpatialReference)

In This Topic

Initializes a new instance of the MultipatchBuilderEx class. Use this constructor to create a cylinder, sphere, sphere frame or cone centered around the of the specified and .

Syntax

Visual Basic (Declaration)
C#

Public Function New( _
   ByVal constructType As MultipatchConstructType, _
   ByVal centerPt As MapPoint, _
   ByVal size As Double, _
   ByVal quality As Double, _
   Optional ByVal spatialReference As SpatialReference _
)

public MultipatchBuilderEx( 
   MultipatchConstructType constructType,
   MapPoint centerPt,
   double size,
   double quality,
   SpatialReference spatialReference
)

Parameters

constructType: The type of multipatch to be constructed.
centerPt: The center point of the Multipatch.
size: The size of the shape (height, length, width). It must be greater than 0.
quality: A value between 0 and 1 inclusive. A higher quality number means more verticies for the shape resulting in a smoother shape.
spatialReference: (Optional)The spatial reference of the Multipatch.

Return Value

A Multipatch.

Exceptions

Exception	Description
System.ArgumentNullException	The centerPt is empty or null.
System.ArgumentException	The size is invalid. It must be greater than 0.
System.ArgumentException	The quality is invalid. It must be between 0 and 1 inclusive.
System.ArgumentException	The constructType is invalid for this constructor.

Example

Construct 3D special Multipatch shapes

{
  var sr = MapView.Active.Map.SpatialReference;

  var extent = MapView.Active.Extent;
  var center = extent.Center;
  var centerZ = MapPointBuilderEx.CreateMapPoint(center.X, center.Y, 500, sr);

  // cube
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Cube, centerZ, 200, sr);
  // tetrahedron
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Tetrahedron, centerZ, 200, sr);
  // diamond
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Diamond, centerZ, 200, sr);
  // hexagon
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Hexagon, centerZ, 200, sr);

  // sphere frame
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.SphereFrame, centerZ, 200, 0.8, sr);
  // sphere
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Sphere, centerZ, 200, 0.8, sr);
  // cylinder
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Cylinder, centerZ, 200, 0.8, sr);
  // cone
  multipatch = ArcGIS.Core.Geometry.MultipatchBuilderEx.CreateMultipatch(MultipatchConstructType.Cone, centerZ, 200, 0.8, sr);

  // use the builder to add materials or textures
  // create the multipatchBuilderEx object
  var builder = new ArcGIS.Core.Geometry.MultipatchBuilderEx(multipatch);
  //   - create a cone with a material
  builder = new MultipatchBuilderEx(MultipatchConstructType.Cone, centerZ, 200, 0.8, sr);

  BasicMaterial faceMaterial = new BasicMaterial();
  faceMaterial.Color = System.Windows.Media.Color.FromRgb(255, 0, 0);
  faceMaterial.Shininess = 150;
  faceMaterial.TransparencyPercent = 50;
  faceMaterial.EdgeWidth = 20;

  foreach (var patch in builder.Patches)
    patch.Material = faceMaterial;

  multipatch = builder.ToGeometry() as Multipatch;
}
