# STLReader

VTKExamples/Python/IO/STLReader

### Description

This code snippet reads an STL file and creates a PolyData output

### Code

STLReader.py

    #!/usr/bin/env python

    import vtk

    filename = "myfile.stl"

    reader = vtk.vtkSTLReader()
    reader.SetFileName(filename)

    mapper = vtk.vtkPolyDataMapper()
    if vtk.VTK_MAJOR_VERSION <= 5:
        mapper.SetInput(reader.GetOutput())
    else:
        mapper.SetInputConnection(reader.GetOutputPort())

    actor = vtk.vtkActor()
    actor.SetMapper(mapper)

    # Create a rendering window and renderer
    ren = vtk.vtkRenderer()
    renWin = vtk.vtkRenderWindow()
    renWin.AddRenderer(ren)

    # Create a renderwindowinteractor
    iren = vtk.vtkRenderWindowInteractor()
    iren.SetRenderWindow(renWin)

    # Assign actor to the renderer
    ren.AddActor(actor)

    # Enable user interface interactor
    iren.Initialize()
    renWin.Render()
    iren.Start()
