[vtk-developers] Tcl wrapping and output array arguments

[David Gobbi]

No, neither the Tcl wrappers or the the Java wrappers can wrap
vtkBoundingBox as an "object".  But they could convert it into an
array of six floats.  For example, if a method takes an argument
of type "vtkBoundingBox" in C++, it could be wrapped as a Tcl
method that takes six floats.  If a method returns a vtkBoundingBox
in C++, it could be wrapped as a Tcl method that returns six floats.
