Trackball

from panda3d.core import Trackball
class Trackball

Bases: MouseInterfaceNode

Trackball acts like Performer in trackball mode. It can either spin around a piece of geometry directly, or it can spin around a camera with the inverse transform to make it appear that the whole world is spinning.

The Trackball object actually just places a transform in the data graph; parent a Transform2SG node under it to actually transform objects (or cameras) in the world.
