# This example creates a polygonal model of a cone, and then renders it to
|
||
|
|
# the screen. It will rotate the cone 360 degrees and then exit. The basic
|
||
|
|
# setup of source -> mapper -> actor -> renderer -> renderwindow is
|
||
|
|
# typical of most VTK programs.
|
||
|
|
#
|
||
|
|
|
||
|
|
#
|
||
|
|
# First we include the VTK Python packages that will make available
|
||
|
|
# all of the VTK commands to Python.

|
|

|
#
|
||
|
|
# Next we create an instance of vtkConeSource and set some of its
|
||
|
|
# properties. The instance of vtkConeSource "cone" is part of a visualization
|
||
|
|
# pipeline (it is a source process object); it produces data (output type is
|
||
|
|
# vtkPolyData) which other filters may process.
|
||
|
|
#
|
||
|
|
cone = vtk.vtkConeSource()
|
||
|
|
cone.SetHeight( 3.0 )
|
||
|
|
cone.SetRadius( 1.0 )
|
||
|
|
cone.SetResolution( 10 )
|
||
|
|
|
||
|
|
#
|
||
|
|
# In this example we terminate the pipeline with a mapper process object.
|
||
|
|
# (Intermediate filters such as vtkShrinkPolyData could be inserted in
|
||
|
|
# between the source and the mapper.) We create an instance of
|
||
|
|
# vtkPolyDataMapper to map the polygonal data into graphics primitives. We
|
||
|
|
# connect the output of the cone souece to the input of this mapper.
|

|

coneMapper = vtk.vtkPolyDataMapper()

coneMapper.SetInputConnection( cone.GetOutputPort() )

#
|
||
|
|
# Create an actor to represent the cone. The actor orchestrates rendering of
|
||
|
|
# the mapper's graphics primitives. An actor also refers to properties via a
|
||
|
|
# vtkProperty instance, and includes an internal transformation matrix. We
|
||
|
|
# set this actor's mapper to be coneMapper which we created above.

#
|
||
|
|
# Create the Renderer and assign actors to it. A renderer is like a
|
||
|
|
# viewport. It is part or all of a window on the screen and it is
|
||
|
|
# responsible for drawing the actors it has. We also set the background
|
||
|
|
# color here
|

ren1.SetBackground( 0.1, 0.2, 0.4 )
|
||
|
|
|
||
|
|
#
|
||
|
|
# Finally we create the render window which will show up on the screen
|
||
|
|
# We put our renderer into the render window using AddRenderer. We also
|
||
|
|
# set the size to be 300 pixels by 300

# now we loop over 360 degreeees and render the cone each time
