Some functions use output arguments to return multiple values in scripting languages that support them (such as VBScript). For example, the NurbsCurve.Get method returns a complete data description of the Nurbs Curve all using output arguments:
Set oSpiral = ActiveSceneRoot.AddGeometry( "Arc", "NurbsCurve" ) oSpiral.ActivePrimitive.Geometry.Curves(0).Get siSINurbs, aCtrlPts, aKnots, bClosed, lDegree, eParFactor LogMessage "INFORMATION FOR " & oSpiral & ":" LogMessage "==========================================================================" LogMessage "Control Points:" For i = 0 to UBound( aCtrlPts, 2 ) LogMessage "x = " & aCtrlPts(0,i) & _ "; y = " & aCtrlPts(1,i) & _ "; z = " & aCtrlPts(2,i) Next LogMessage "---------------------------------------------------------------" LogMessage "Knots:" For j = 0 to UBound( aKnots ) If j = 0 Then sKnotArray = aKnots(j) Else sKnotArray = sKnotArray & ", " & aKnots(j) End If Next LogMessage sKnotArray LogMessage "---------------------------------------------------------------" If bClosed Then LogMessage oSpiral & " is closed." Else LogMessage oSpiral & " is not closed." End If LogMessage "---------------------------------------------------------------" LogMessage "Degree of " & oSpiral & " is " & lDegree & "." LogMessage "---------------------------------------------------------------" Select Case eParFactor Case siUniformParameterization LogMessage oSpiral & "'s knot parameterization is uniform." Case siNonUniformParameterization LogMessage oSpiral & "'s knot parameterization is non-uniform." Case siChordLengthParameterization LogMessage oSpiral & "'s knot parameterization is chord-length." Case Else LogMessage oSpiral & "'s knot parameterization is centripetal." End Select
This example outputs the following information to the Script Editor in Softimage:
