If you have a scene that you want to render in VTK, the easiest would be to
build a vtkDataset (vtkPolyData most likely) and then
render that in VTK. You don't need to worry about the OpenGL transform or
interaction as VTK does this for you.
Take a look at
Cxx / GeometricObjects
for examples of how to do this.
