[vtkusers] Creating a Lego Brick out of vtk primitives

[Daniel Zuidinga]

Hello vtk users,

i try building a lego brick with vtk primitives and addinputconnection. 
Is inputconnection the wrong method to add geometry-data to a mapper?
Nothing is shown when i add a inputconnection.

my code (java):

         vtkCubeSource cube = new vtkCubeSource();
         vtkPolyDataMapper mapper = new vtkPolyDataMapper();
         mapper.SetInputConnection(cube.GetOutputPort());

         vtkCylinderSource src2 = new vtkCylinderSource();
         vtkPolyDataMapper mapper2 = new vtkPolyDataMapper();
         mapper.AddInputConnection(src2.GetOutputPort());


regards
