IMarker3DSymbol Interface

Provides access to members that control the 3D marker symbol.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires 3D Analyst Extension.

Description

The IMarker3DSymbol interface provides properties and methods to define 3D marker symbols. The CreateFromFile method enbles import of existing OpenFlight (.flt), 3ds max* (.3ds), or Virtual Reality Markup Language (VRML*) models and then symbolize point features with these models. RestrictAccessToShape restricts the access to the geometry of a 3D marker symbol. IsRestrictedAccess indicates whether the geometry of the 3D Marker Symbol is restricted. UseMaterialDraping is used to display the symbols with or without texture materials.

Members

Description
Method CreateFromFile Imports the symbol definition.
Read-only property IsRestricted Indicates if the marker restricts access to internal shape.
Read-only property MaterialCount Number of materials present.
Method RestrictAccessToShape Restricts all further access to internal shape.
Read/write property Shape Marker shape geometry.
Read/write property Thumbnail The symbol thumbnail for 2D representation.
Read/write property UseMaterialDraping Indicates if the marker uses material property for draping.

The code below shows how to symbolize a point graphic with a 3D Marker Symbol.

Public Sub Symbolize_Marker3DSymbol()
  
  Dim pSxDoc As ISxDocument
  Set pSxDoc = ThisDocument
 
  Dim pScene As IScene
  Set pScene = pSxDoc.Scene
 
  Dim pGraphicsLayer3D As ILayer
  Set pGraphicsLayer3D = pScene.BasicGraphicsLayer
 
  Dim pGraphicsContainer3D As IGraphicsContainer3D
  Set pGraphicsContainer3D =  pGraphicsLayer3D
   
' Define a point location
  Dim pPt As IPoint
  Set pPt = New Point
  pPt.PutCoords 100, 100
  pPt.Z = 0

' Define a new Marker3DSymbol
  Dim pMarkerSym As IMarker3DSymbol
  Set pMarkerSym = New Marker3DSymbol
   
  pMarkerSym.CreateFromFile "C:\marker3dsymbol.3ds"
  pMarkerSym.UseMaterialDraping = True
 
  Dim pMarker3DPlace As IMarker3DPlacement
  Set pMarker3DPlace = pMarkerSym
 
  Dim pElement As IElement
  Set pElement = New MarkerElement
  Dim pMarkerElement As IMarkerElement
  Set pMarkerElement = pElement
 
  pMarkerElement.Symbol = pMarkerSym
  pElement.Geometry = pPt
  pGraphicsContainer3D.AddElement pElement
 
  pScene.SceneGraph.ActiveViewer.Redraw False
 
End Sub
