How to visualize a texture inside in sphere

[Torlo, Marc]

Is it possible to render a texture inside a sphere (for example: to render a
sky) ? The following sample code will only render the image on the outside
surface. It worked with vtk2.2.
 
 vtkSphereSource *sphere = vtkSphereSource::New();

 vtkTextureMapToSphere *tmapper = vtkTextureMapToSphere::New();
 tmapper->SetInput(sphere->GetOutput());
 tmapper->PreventSeamOn();
 
 vtkTransformTextureCoords *xform = vtkTransformTextureCoords::New();
 xform->SetInput(tmapper->GetOutput());
 
 vtkDataSetMapper *mapper = vtkDataSetMapper::New();
 mapper->SetInput(xform->GetOutput());
 
 vtkTexture  *texture  = vtkTexture::New();
 
 vtkBMPReader *picReader = vtkBMPReader::New();
  picReader->SetFileName("something");
 
  texture->SetInput(picReader->GetOutput());
  texture->InterpolateOn();
 
  my_actor->SetMapper(mapper);
  my_actor->SetTexture(texture);
 
Thank You for your help.
