[Insight-users] Multiple vtk3DSImporter importers in a render window

[Dora Szasz]

Hello itk users,



How can I integrate in a render window multiple vtk3DS importers?
I have tried the following code in Tcl, but I have received the following error: "Object named importer could not find requested method: GetOutputPort", so the importer is not behaving like a reader.

How can I do this? 


Thank you a lot,
Dora Szasz
