# This example demonstrates how to use multiple renderers within a
|
||
|
|
# render window. It is a variation of the Cone.py example. Please
|

|
|
# refer to that example for additional documentation.

# 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.

#
|
||
|
|
# 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.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 two renderers and assign actors to them. A renderer renders into a
|
||
|
|
# viewport within the vtkRenderWindow. 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. In this example we are adding the same actor
|
||
|
|
# to two different renderers; it is okay to add different actors to
|
||
|
|
# different renderers as well.
