## Cluster.Elements

### Description

Returns a ClusterElementCollection which provides access to the mapping between the indices of the Cluster and the associated indices on the Geometry. This is important for clusters which contain only a subset of the components. For example the point at index 10 in the cluster might be point 456 on the geometry.

### C# Syntax

    // get accessor
    ClusterElementCollection rtn = Cluster.Elements;

### Examples

#### VBScript Example

    ' This example demonstrates how Cluster indices are mapped to indices of the points
    ' on the Geometry via the Cluster.Elements property
    NewScene ,false
    set oSphere = ActiveSceneRoot.AddGeometry( "Sphere", "MeshSurface" )
    ' Create a cluster that only contains some of the points.
    set oCluster = oSphere.ActivePrimitive.Geometry.AddCluster( _
                                    siVertexCluster, "MyFrontPoints", Array( 5,10,12 ) )
    set oClusterElements = oCluster.Elements
    aElements  = oClusterElements.Array
    for iElement=lbound(aElements,1) to ubound(aElements,1)
            logmessage "Cluster item " & iElement & _
                         " refers to point " & aElements(iElement) & " on the Geometry"
    next
    'Output of this script is:
    'INFO : "Cluster item 0 refers to point 5 on the Geometry"
    'INFO : "Cluster item 1 refers to point 10 on the Geometry"
    'INFO : "Cluster item 2 refers to point 12 on the Geometry"//
