[vtkusers] Mix Tcl and C++

[Johanna]

Thank you for your help.

What I have is a number of tcl scripts that read and process image data (The Visible Human dataset), and create a number of actors. 

Now I would like to display these images in a VR environment consisting of three displays. For this purpose I will use Performer, and I have found a class called vtkActorToPF who can translate the vtkActor into a node in Performer and then use Performer to render the scene. 

The Performer file will be written in C++ and this is the file in which I would like to use vtkActorToPF, i.e. make the translation from vtk to pf. Therefore I have to access the actors created in the tcl script from a c++ file, to be able to use vtkActorToPF.

F, i.e. make the translation from vtk to pf. Therefore I have to access the actors created in the tcl script from a c++ file, to be able to use vtkActorToPF.
