[vtkusers] HowTo move vtkVectorText to viewers direction.

[kitknow]

Hi!

How can i move a text to viewers direction? My aim is that i want to be able
to read the text from every position of the viewer. Anyone an idea? :)

here a part of the code:

           vtkVectorText *pVectorText = vtkVectorText::New();
           pVectorText->SetText( caption.c_str() );

           vtkDataSetMapper *pTextMapper = vtkDataSetMapper::New();
           pTextMapper->SetInputConnection( pVectorText->GetOutputPort() );

           vtkFollower *pTextActor = vtkFollower::New();
           pTextActor->SetMapper( pTextMapper );
           pTextActor->SetPosition( xPos, yPos, zPos );

           pRenderer->AddActor( pTextActor );
