# Create the "Hello" text that will follow the camera.
text_mesh = pv.Text3D('Hello', depth=0.1)

# Create mapper and follower actor for the text.
text_mapper = pv.DataSetMapper(text_mesh)

# Create a transparent cube that doesn't follow the camera.

)

# Set the follower's camera and show the scene.
