manipulating viewpoint

[jaylocco]

Just wana share

I have just discovered the way to make the viewpoint move like roller coaster.
First we need to animate the path using control points then set the move mode as Cubic Bezier. in order to get the view moves as well, link pos the view with the car

link = viz.link(car, viz.MainView)
link.setMask(viz.LINK_POS)

for reference check the animatepath.py in the Help section

BUT does anyone have any idea how to do the Tank turret problem I sent earlier?
