VBScript Example

    ' This example show how to print out the point positions and
    ' the triangle data for a polygon mesh
    set oRoot = Application.ActiveProject.ActiveScene.root
    set oCube = oRoot.AddGeometry( "Cube", "MeshSurface" )

    set oGeometry = oCube.ActivePrimitive.Geometry
    set oTriangles = oGeometry.Triangles
    aIndexArray = oTriangles.IndexArray
    aPointArray = oGeometry.Points.PositionArray

    Application.LogMessage "Object: " & oCube.Name
    Application.LogMessage "points: " & UBound( aPointArray, 2 )-LBound( aPointArray, 2 )+1

    ' print out the x,y,z positions of each point
    for i=LBound( aPointArray, 2 ) to UBound( aPointArray, 2 )
       Application.LogMessage vbTab & _
           aPointArray(0,i) & "," & _
           aPointArray(1,i) & "," & _
           aPointArray(2,i)
    next

    Application.LogMessage "triangles: " & UBound( aIndexArray, 2 )-LBound( aIndexArray, 2 )+1

    ' print out the point indices for each triangle
    for i=LBound( aIndexArray, 2 ) to UBound( aIndexArray, 2 )
       Application.LogMessage vbTab & _
           aIndexArray(0,i) & "," & _
           aIndexArray(1,i) & "," & _
