# This example demonstrates how the off-screen capabilities
|
||
|
|
# of Mesa can be used in VTK.
|
||
|
|
# Note that to be able to run this example, you need to compile
|
||
|
|
# VTK with mangled Mesa. See the README.txt file in this directory
|
||
|
|
# for instructions on how this can be done.

# Create Mesa specific render window and renderer
|

|
|
# When using Mesa, you should always create Mesa specific renderers,
|
||
|
|
# render windows, mappers, actors, lights, cameras etc...
|

|

# See the Mesa classes in the Rendering directory for a list of
|

|
|
# existing classes.
