# This example demonstrates the use of vtkSTLReader to load data into VTK from
# a file. This example also uses vtkLODActor which changes its graphical
# representation of the data to maintain interactive performance.
#
# First we include the VTK Tcl packages which will make available
# all of the vtk commands to Tcl
#
package require vtk
package require vtkinteraction
# Create the reader and read a data file. Connect the mapper and actor.
vtkSTLReader sr
sr SetFileName $VTK_DATA_ROOT/Data/42400-IDGH.stl
vtkPolyDataMapper stlMapper

# Create the Renderer, RenderWindow, and RenderWindowInteractor
