public void SetU3dPath( string u3dPath )
Public Sub SetU3dPath ( u3dPath As String() )
The first string in the array is a node ID for the root view node. Each subsequent string is the node ID for a child of the view node specified by the prior string. Each view node specifies a 3D transformation matrix; the concatenation of all the matrices forms the camera-to-world matrix.
When u3dPath contains a single string, it is written as a CosString object in a PDF file.
