Can I show a VTK scence in 3d view?

I created a scence with some meshes(2 layer,such as 1st:cube,2nd:cylinder) and pictures by import vtk in slicer, I want to show it in 3D view of slicer. Can I do it with python. Thanks!

You can load and display a mesh file in Slicer by calling:

slicer.modules.models.logic().AddModel("path/to/modelfile.stl")
